In this guide I explain how to disassemble a HP Pavilion dv4 laptop. I’ll be removing the display panel and top cover assembly.
Before you start, make sure the laptop is turned off and battery removed.
STEP 1.
Remove hard drive, memory and CMOS battery covers from the bottom of the laptop.
On the following picture you can see all covers removed.
Now you can get access to both memory modules, hard drive, wireless card and CMOS battery.
I believe HP Pavilion dv4 can handle up to 8GB RAM maximum. It means you can install up to 4GB memory module into each memory slot.
This laptop uses DDR2 PC2-6400 SODIMM memory modules.
For the purpose of my guide it’s not necessary to remove memory modules. I’ll leave them connected.
STEP 2.
Remove three screws securing the hard drive.
Slide the hard drive assemble to the left in order to disconnect it from the motherboard.
Now you can remove the hard drive.
If you are replacing the hard drive, you’ll have to transfer mounting brackets to the new drive.
HP Pavilion dv4 laptop uses a regular 2.5″ SATA hard drive. Any large SATA hard drive should work fine in this laptop.
STEP 3.
Disconnect both antenna cables from the wireless card.
For the purpose of my guide it’s not necessary to remove the wireless card, so I’ll leave it connected to the motherboard.
STEP 4.
Unlock the DVD drive and pull it from the laptop.
STEP 5.
Disconnect and remove the CMOS battery.
In the following 7 steps I explain how to disconnect and remove the keyboard. It’s not necessary go though all previous steps (except removing CMOS battery cover) in order to remove the keyboard.
STEP 6.
Remove three screws securing keyboard on the bottom of the laptop.
STEP 6.
Carefully lift up the top part of the keyboard with a sharp object. Continue removing keyboard with your fingers.
WARNING! It’s possible the keyboard is glued to the top cover with double sticky tape. Remove it slowly.
STEP 7.
Lift up the keyboard and slide it towards the LCD screen so you can access the cable underneath.
STEP 8.
Before you can remove the keyboard it’s necessary to unlock the connector.
STEP 9.
On the following picture the cable connector shown in the locked position.
In order to unlock the connector you’ll have to move the brown clip about 2 millimeters towards the display.
Be careful, the brown clip must stay attached to the white base. Don’t move it more that 2 millimeters.
On the next picture the connector shown in the unlocked state.
Now you can pull keyboard cable from the connector.
STEP 10.
Finally, remove the keyboard.
New keyboards for HP Pavilion dv4 laptops available here.
STEP 11.
Remove seven screws securing keyboard bezel. Don’t forget two screws in the DVD drive bay.
STEP 12.
Disconnect LED board cable from the motherboard.
Remove two screws securing keyboard bezel to the top cover.
STEP 13.
In order to remove the bezel, slide it towards the display and lift up.
STEP 14.
Disconnect the power button board cable from the motherboard.
Remove one screw securing the board.
Remove power button board.
STEP 15.
Disconnect speaker cable from the motherboard.
Disconnect lid switch cable from the motherboard.
Remove three screws securing the speaker assembly.
STEP 16.
Lift up and remove speaker assembly.
STEP 17.
Disconnect video cable connector from the motherboard.
Pull wireless card antenna cables through the hole in the top cover. We disconnected both antenna cables from the wireless card in the step 3.
STEP 18.
Remove four screws securing display assembly hinges.
STEP 19.
Lift up and separate the display panel assembly from the laptop base.
If you would like to disassemble the display panel and remove the LCD screen, you can follow this LCD screen removal guide for HP Pavilion dv4 laptop.
By the way, it’s not necessary to separate the display panel from the laptop base in order to remove the screen.
STEP 20.
Remove six remaining screws from the bottom of the laptop.
STEP 21.
Remove four screws securing the top cover.
Disconnect touch pad cable from the motherboard (yellow arrow).
If you have finger scanner installed, disconnect it too (green arrow).
STEP 22.
It’s not necessary, but you can disconnect the USB cable.
It will be easier to remove the top cover when this cable removed.
STEP 23.
Carefully lift up and separate the top cover assembly from the laptop base.
STEP 24.
Remove top cover assembly.
On the following picture you can see the laptop base with the top cover removed.
I’m not going to remove the motherboard but you can find instructions in the official HP service manual (available from HP website).
If you would like to clean the cooling fan and heatsink (to fix overheating), you can do it without removing the motherboard. Just used canned air and blow air into the fan until all dust is gone.
By the way, in HP Pavilion dv4 laptop the DC jack is not soldered to the motherboard.
If the jack is damaged, you can replace it with a new one without soldering. Simply unplug the damaged DC jack harness and replace it with a new DC jack harness which is available here.

Thanx a lot !!!!
January 21st, 2011 at 10:53 am
I have a problem that the DVD would not eject using the latch only as described. Is there a screw that needs to be removed somewhere? Otherwise, my compliments on the great instructions.
January 23rd, 2011 at 10:42 pm
FMM,
I don’t think so. Slide the latch and wiggle the optical drive a little bit to remove it from the laptop.
There shouldn’t be any screw securing the drive.
January 28th, 2011 at 9:41 am

January 31st, 2011 at 2:16 pm
I want to thank you for the incredible, helpful site you put together!
I dropped you some change via PayPal.
It seems only right for how you helped.
There are other helpful sites, but I know when I come to you,
it will be a painless disassembly, unless of course I read to fast
Thank You again!

Joe Peach,
Thank you for your donation. I’m glad you found this guide useful.
February 17th, 2011 at 1:47 am
i got my escape key coming out of my keyboard.. tell me how to fix it again ?
i hav hp dv 4 laptop
February 17th, 2011 at 12:04 pm
James,
You can try reattaching the key back to the keyboard using this technique: http://www.laptoprepair101.com/laptop/2007/03/20/key-fell-off-keyboard/
If the key or retainers are damaged, you’ll have to replace the keyboard.

This website is awesome!
I own a HP Pavilion dv4t-1200 CTO notebook. My problem is that the screen display has started shaking. Also I can see fine lines near the bottom edge and top edge of my lcd display. The display however is nice and bright. Also, while connecting it using an HDMI cable to an external display, it has no shake and the display is perfect. Is this a loose connection problem?
I opened my laptop and reconnected the main video cable to the motherboard, thinking it may have come loose. But the problem is still there.
I did nould this be due to loose cot check the inverter connections. Connections of the cables with the inverter?
February 23rd, 2011 at 9:16 pm
Vikram,
It’s possible you have bad video cable or failing LCD screen. I would try replacing the cable first. If it doesn’t help, move to the LCD screen.
No, it’s not related to the inverter.
When you have a problem with the inverter board, the screen backlight goes off.
February 27th, 2011 at 11:18 am
got problem with my pc.,., sometimes it open.,., the power light apeears but the screen is never sometimes?? what is it what will i do
March 6th, 2011 at 9:01 am
Hi. Do I have to go through all these steps to clean the fan and heat sink? I think I do.
To assemble back, I’m guessing I’ll just read the guide again from bottom to top, right?
Also, will the system run normally after reassembly? Or will it ask me to go through some setup config first?
Thanks! Great guide!
March 10th, 2011 at 11:39 pm
carlosfsm,
Try cleaning it with compressed air. This doesn’t require laptop disassembly at all. Just blow air into the fan grill on the bottom until all dust is gone.
That’s right.
If you assemble everything correctly, it should start right away. No setup/configuration needed.
March 18th, 2011 at 2:34 pm
I have an HP G61-511WP with a broken screen. I don’t see anything on this website on how to remove the LCD screen for this particular model. Could anybody help please?
March 18th, 2011 at 4:00 pm
Michael,
I don’t have instructions for this particular model but I think it should be similar to one of the following guides:
http://www.insidemylaptop.com/replace-broken-lcd-screen-hp-pavilion-dv3-laptop/
or
http://www.insidemylaptop.com/remove-lcd-screen-from-hp-pavilion-dv5-laptop/
March 25th, 2011 at 9:58 am
Hi I have a hp dv4 1145go and i cant see anything on my screen, its on i can put contrast up n down and see it get lighter and darker. i hooked it up to an external monitor and the computer works great. what do you think the problem might be . ittok it to bb and they said it would cost 389.00 and i cant do that any help Thanks
March 27th, 2011 at 10:49 am
Michael,
I just took some pictures for replacing broken screen on a HP G62 notebook, it could be similar to your HP G61. I’ll compile a new disassembly guide soon.
March 27th, 2011 at 10:51 am
oneluv06,
It’s hard to tell what is wrong. Could be one of the following:
1. Bad connection between the video cable and motherboard. Try reconnecting the cable.
2. Defective video cable. Try replacing the cable.
3. Failed LCD screen. Try replacing the screen.
March 27th, 2011 at 5:28 pm
Hi,
I think that my computer has an issue with the DC jack. Before i take the entire computer apart is there any way to test it?
If
My battery says it needs to be replaced but I feel the computer should work with out the battery when it is plugged in to an electrical outlet. I remove the battery from the computer shouldn’t it still work with electrical power?
Thanks, Gladys
March 30th, 2011 at 8:35 pm
website was extremely helpful in disassembling my laptop. My computer was not getting power but it worked when the battery is charged. I replaced the dc jack, however, the laptop is still not getting power. Any idea what the problem can be?
March 31st, 2011 at 7:32 am
Luke,
It’s possible you have a problem with the AC adapter. Maybe the AC adapter doesn’t work correctly when loaded (laptop turned on). I’ve seen failures like that a few times before. You’ll have to find another working AC adapter to test the laptop.
If the problem still exists even after replacing the adapter, most likely this is motherboard failure.
April 7th, 2011 at 1:23 am
hey, i use a pavilion dv4 1502tu, my display cable is damaged. is there any way i can get it fixed? when i connect my laptop to the external display everything else works fine. and if i have to replace it. can u suggest me where can i get the replacement part?
April 8th, 2011 at 3:44 pm
hello my dv4t laptop keeps showing me a white screen whenever i turn it on.
could it be the video card? video cable?
When i try to run it using an external monitor.. the monitor comes up black as if though its not getting any signal
thanks!
April 8th, 2011 at 5:34 pm
Sudip,
Could be bad connection between the video cable and LCD screen. Try reconnecting the cable.
It’s possible the laptop doesn’t start with external monitor because the internal monitor still connected to the motherboard.
You can try disconnecting the video cable from the motherboard and try starting the laptop with the external monitor. Can you get external image when internal screen disconnected from the motherboard?
April 8th, 2011 at 5:52 pm
yashrestha,
Yes, it’s possible to replace the video cable but you’ll have to disassemble the display panel.
You can follow this guide for HP Pavilion dv5 laptop which should be very similar.
http://www.insidemylaptop.com/remove-lcd-screen-from-hp-pavilion-dv5-laptop/
You can search for a new cable using display cable part number listed in the service manual: http://h10032.www1.hp.com/ctg/Manual/c01597750.pdf
The display cable part number mentioned on the page 27.
It says: LCD cable for Flush Glass display assemblies 486878-001
April 16th, 2011 at 7:16 pm
Hello and thank you for the very detailed instructions.
Will you be showing instructions for removing the motherboard from the base. I’ve tried to use both your instructions for HP Pavilion DV5 and the service manual for DV4 (page 107-109) and removed the DC Jack cable, audio cable, 2 slotted screws in the expansion port, one screw in the bottom right corner of the motherboard plus another screw but it still seems pretty securely attached and didn’t want to break anything, pulling more than it seems to want to give. Also couldn’t find the modem module cable to disconnect. I want to change the broken battery latch and it’s just behind the motherboard.
Also, you mentioned in your response to a post above that problems with inverter board would result in the screen backlight not working. Does that mean that there will be no image or a dim image? I’m sorry if that’s a stupid question but this is my first time taking apart a computer. My screen comes on but either comes up pink/red or green depending on the angle that the screen is tilted. I’m guessing that it’s a bad video display cable and should replace that? I have not tested it with an external monitor as I’m not quite sure how that’s done. Would I just plug the monitor into the HDMI port? I have already taken apart the computer and put it back together again and checked to make sure the cable connections are all secure but the screen still goes pink or green.
Thank you for your assistance and I hope I was clear enough.
April 17th, 2011 at 12:14 pm
Sorry, I just found the modem module cable. It was wrapped under the modem module and I used the service manual (page 99-100) to remove module in order to access the cable itself.
And looking around the internet, realize that I won’t use the HDMI port but the VGA port to connect to external monitor?
Thank you.
April 17th, 2011 at 4:21 pm
Hello again and sorry, but I figured out that I needed to also remove the WLAN card in order to release the motherboard from the base enclosure as well as disconnecting the cable to the fan. Guess I answered my own question.
I would still like your feedback on why the screen has pink/reddish or green/bluish tones. This web page here has an image of a screen with that pinkish tone that comes up on my screen:
http://www.laptoprepair101.com/laptop/2007/09/05/troubleshooting-laptop-with-backlight-failure/
Thank you and apologize for these multiple messages. Please delete them if you feel that it’s cluttering up your comments.
April 19th, 2011 at 10:36 pm
Thùy,
When inverter fails, you still should see a very dim image on the screen.
Most likely it’s one of the following:
1. Bad connection between the video cable and motherobard. Try reconnecting the cable.
2. If it doesn’t help, this could be defective video cable. Try replacing the cable.
3. If the problem still there, most likely this is LCD screen failure. Try replacing the screen.
Yes, you can do that. Either HDMI port or VGA port. It depends on which port and cable you have.
Feels like bad cable to me.
LOL. This is my article too.
From my experience a failing backlight lamp can cause pinkish tone on the sreen BUT not green tone.
I don’t think that your problem is related to the backlight.
Try replacing the cable first.
April 24th, 2011 at 4:37 pm
Hello, I took it apart to fix the power jack. Now I have all these different type of screws. Which ones goes where?
May 1st, 2011 at 12:17 pm
I have a dv4-1225dx, everything comes on, i can hear windows start up, I use avast antivirus and i can hear it update, I can also use the keyboard to shut the laptop down. My problem is, I have no display, the LCD seems to have the back light on, but nothing else. I have tried to hook up the laptop to my flat screen tv through the VGA connector,but no display there either, havent tried the HDMI output as I have no cable. It has a ATI Radion HD 3200 video card and I am assuming it is not replaceable. Any ideas as what I can do to fix it?
May 20th, 2011 at 7:29 am
Robert,
I have the same problem with my dv4-2160us and mine would also not connect to my flat screen tv through either a VGA or an HDMI cable. I am currently having success hooking it up to a standard LCD computer monitor via VGA so that I can recover my files. I will keep you posted on my progress. If anyone has had this problem or has any suggestions, PLEASE SHARE!
May 20th, 2011 at 2:04 pm
Hank,
It’s possible you have to choose the right channel on your TV in order to get the image.
May 22nd, 2011 at 11:30 am
hello,
i have a dv4 1241 and have gone through all of your steps regarding cleaning the heat sink but in the meanwhile during assembling back i missed connecting the lid switch as in step 15 and i think it has been removed from the other end and fixed on motherboard , so please let me know if the cable is damaged or the position where it was initially attached (other then motherboard end)…..
June 4th, 2011 at 10:05 am
I disassembled my dv4-1241 tx, i mounted it back, but misplaced some of the screws here and there. i also cleaned, fan, heatsink, CPU and GPU. I reapplied thermal paste on CPU and GPU. CPU is working very fine. It hardly crosses 65C while gaming. But my GPU is working weird. When i boot the laptop, GPU temp is 75C. While gaming it crosses 100C. Please somebody help
Thanks in advance
June 4th, 2011 at 10:29 am
This is an excellent instruction tutorial on tearing down the laptop. I have a dv4 that has been running so hot, it has occasionally stopped, even with a fan cooler. I tried cleaning, no good. Finally I decided to bite the bullet and tear it down. This made it easy. Although I have built many a desktop, I’ve never torn down a lap top. Actually getting the mobo out was still pretty hard. something was caught around the video port. Probably the flexible metal bracket. I cleaned and regreased the cpu, and when I blasted some canned air on the fan (now readily accessible), it tossed out a couple of big chunks of dust bunnies that felt like, well, felt.
When I put it together the first time it didn’t work! Graphics processor error. Tore it down. taped the loose connector tightly in place (come on HP!). Voila, it works, and with crossed fingers, I hope it keeps on keepin’ on.
Thanks again for the great tutorial.
June 5th, 2011 at 8:25 am
@ Pranav,
Not sure what’s going on but let me guess.
When you removed the heat sink, do you remember if you had thermal pad covering the GPU?
Did you remove the thermal pad and applied thermal paste on the GPU instead? If you did, that’s why the GPU overheats.
If you have thermal pad before, you have to use thermal pad again.
June 19th, 2011 at 11:41 am
Quick question. For HP dv4t-1000 series, do they all share the same keyboard? So if I buy a keyboard from ebay for the 1100 series, would it work for the 1300 series?
July 4th, 2011 at 12:13 pm
Re: John Wilbur, loose graphics card connector
Hello! I disassembled my dv4 also to clean out fan (with this awesome guide) but upon putting it back together i am getting a non-start up due to the graphics card (four blinking lights).
I was wondering what connector you had to tape down when you had this problem and where to find it? Hopefully my comp i not dead
thanks.
July 7th, 2011 at 12:55 am
thank you very much for this tutorial,
I follow many instructuction before I succes disassemble my hp pavilion dv3.
July 12th, 2011 at 12:19 pm
hi! i just had trouble in taking out the bios battery. did you push it towards the main battery slot? or did you just pull it up? i tried both to no avail. thanks
July 19th, 2011 at 8:47 pm
Thank you so much for making this guide. It really helped me to properly tear down my laptop so that I could clean the dust from 3 years of use.
I should have reassembled in the same order as disassembly because I messed up by routing the USB cable below the grey plastic, causing my battery to fail to sit properly and for the battery ejector to be stuck.. I noticed it after I had already completed reassembly, of course, so I had to go back and fix it, wasting about 45 minutes. So be sure to test all moving parts before reassembly.
However, thanks to your guide, I’m finally up and running, with new thermal paste and dust-free! Thanks
August 15th, 2011 at 1:28 pm
Great documentation!!
I do have one problem with the assembly. I can’t find where the two wires coming from the display panel attach. I have followed them from the display panel down through the hole, but can’t find where they connect.
Please Help me!!
Thanks,
Mel Anderson
August 16th, 2011 at 5:57 am
In relation to not finding the place for the “two wires” coming from the display panel, I found it in step 3. The old saying, “If all else fails, read the manual certainly applies!!
Thanks very much,
Mel
August 20th, 2011 at 10:04 am
I love this site for articles such as this one! Great tutorial for those that fix laptops and also useful for anyone who is just curious. With as many HP DV4 screen issues I have seen, this article is a really good quick visual reference. Thank you for creating it!!
October 29th, 2011 at 6:50 pm
That’s a outstanding,really i want to give thanks to the owner of this website.from this i can assemble some specific laptops myself.thanks again sir…
November 16th, 2011 at 12:10 pm
Thanks guys,
I hope this disassembly guide is useful and helpful for all DIYers.
December 29th, 2011 at 11:28 am
[...] For the laptop base disassembly please read my previous HP Pavilion dv4 disassembly guide. [...]
February 3rd, 2012 at 3:03 am
Wow, you saved my life. Was desperate to do it. Thanks a lot
March 27th, 2012 at 6:43 am
Hi
Can someone please tell me exactly where the card reader cable is located on the HP pavilion DV4? I am trying to disconnect the card reader cable itself and not from the MB and I am having trouble finding out where its located.
Thank You
May 16th, 2012 at 9:49 am
Great details with great photos! Thanks so much. I’m hoping I can fix my webcam problem and get the fan really clean, so I can sell this laptop to help pay for my new one. =)
June 2nd, 2012 at 6:36 am
Hello thank you.
I’m a computer idiot and yet by following your clear and detailed instructions, I managed to bring my laptop back to life again TWICE. The first time happened a year ago with fan problem and the second time was bad connection between the video cable and LCD screen that I fixed yesterday.
Thanks again.
June 19th, 2012 at 7:16 am
Excellent tutorial! I needed to disassemble my wife’s laptop because she spilled iced tea on the touchpad and the touchpad started acting up. After removing and rinsing the touchpad with water and drying it everything is working properly.
I followed the directions exactly except for step #20. For my laptop (DV4-1283cl) I had to remove a seventh screw inside the hard drive bay to get the top cover assembly off. It is a black screw located on the left side inside the drive bay. Probably just a variation in the models.
I’d like to give a big THANK YOU to the author.
June 20th, 2012 at 3:36 pm
can you tell me what the lid switch cable connects to? not the zif end on the mobo but the other end. I just did a fan replacement job and it appeared to not connect to anything! now the customers volume buttons etc don’t work. I see they sell just that cable piece so it’s repairable but I couldn’t find any info on how to connect it on the non zif end.
June 27th, 2012 at 6:53 am
disregard my last post! different cable.
July 21st, 2012 at 1:47 pm
Hi and Thank you for you great breakdown. I took apart my DV4 thinking I had a bad DC jack on the side but when I applied a multimedia to the other end of the power cable that connects direct to the motherboard I got 19 volts. It seems the motherboard is getting power but still not turning on. I tried the electrostatic dissipation trick but still nothing(hold down the power button for 1 minute without a battery or charger plugged in. I think it’s probably a bad motherboard but I’m not sure. Is there anything else I might have missed?
July 23rd, 2012 at 10:56 am
@ wolf3345us,
It’s not turning on at all? Could be the power button board failure (shown in the step 14).
If the laptop turns on but there is no video, could be memory failure.
It’s not very clear from your description how the laptop is failing.
July 26th, 2012 at 7:56 am
Hi Thanks for the detailed description to open it. Here is a problem. I have HP dv4-1225 dx with Windows 8 OS. Recently i had a problem that while switching on, the system switches on but i dont see any video, rather seeing capslock and numlock LEDs blink, continously. If i leave it on for a while, sometimes the whole system switches on. Considering the problem with Win8 OS, i tried with Linux, but the system didnt boot up. I have no clue. But for a long time, the system was warning me about the internal battery replacement. so can it be the major cause for the present problem. I couldnt think anything else, since, while it switches on occasionally everything works well, seems my hard drive, mother board and other things are working. I would be happy to provide more info if you need. Thanks a lot for your help.
July 27th, 2012 at 2:57 pm
@ John,
Check the memory modules. Try reseating them. Test the laptop with only one module installed. This could be memory related failure.
August 1st, 2012 at 12:53 am
HI Mr. Great Guy , heres my probs , i have the same model as this Laptop youve’d shown to dis assyble method . Now heres the error codes numlock & capslocks blinks every 4 seconds , somebody told me and give me error codes for this matter . now where is video chip controller is located to this motherboard so that i can resolder it by me self. HP Service Center Saudi Arabia dont have a clue for this or never touch if it is this case. i’ll try to cross my finger even though to try to make this crap alive again . Tnx.
August 1st, 2012 at 5:39 pm
@ Diego,
First of all, remove the hard drive and try removing memory modules one by one. Will it start with only one memory module installed?
Take a look at this guide: http://www.laptoprepair101.com/laptop/2011/02/23/fix-laptop-motherboard-with-failed-nvidia-graphics-chip/
November 18th, 2012 at 10:40 am
Is there a place where I can buy the replacement clips that you lock the ribbon cables in place with? My brother lost one of the clips
November 27th, 2012 at 5:28 pm
Thanks for the pics – helpful in correctly and easily disassembly. I am going to impose on you and ask a question. I replaced the top (the diplay panel) in my dv4 1014nr but I may have made an error. The display fits and works great, but I lost the controls at the top (the touch volume, media player, and wifi on/off switches) and the battery is no longer detectable. Does it seem like I missed some reconnections somewhere?
I would appreciate any information you could give me, if you have time.
December 2nd, 2012 at 8:15 am
Hi, thanks for great breakdown. I have a dv4 that does not connect to power, I’ve already tested my AC adapter and is working. When I connect the laptop on power not even the DC jack led turn on, the only thing that happens is the front power led starts to blink if the batery is in it, but without the batery I get nothing.
December 10th, 2012 at 11:22 am
My Pavilion dv4 turns on boot will not boot. My number lock and caps lock blink at the same time, every 2 seconds? Is there a trouble shooting code chart that can help my figure this out.
Thanks!
December 15th, 2012 at 9:41 am
@ Mike,
First, I would check laptop memory. Try removing memory modules one by one and test the laptop with each module separately. If one of them failed, the laptop should start properly when you remove the failed module.
January 9th, 2013 at 1:34 am
i have a HP Pavilion DX4 2145DX. I think i have a missing module. May i ask what module that isconnected beside the remote compartment.(internal module).
January 18th, 2013 at 4:05 am
I recently upgraded my dv4 to windows 8. but after installing I am facing a lot of heating problem. I never faced it when Win7 was installed. any suggestion?
January 26th, 2013 at 3:24 am
Help!!!! I need help asap please…..
my problem is common I guess…..Thought it was battery problem because battery warning replacement shown couple months back and finally gave out….so bought new battery and adapter..tried every suggestions….no cigars….So……..heres the problem:
Blank screen, fan on, caps and nums lock blink every 3 seconds.

The brown clip that you talked about when removing the keyboard, broke. For the life of me I can’t find a replacement clip. Any ideas? HP is no help!

Great photo’s. How would i replace the SATA connector, i think i bent a pin when i removed the HD? Is there a quick way or do i need to basically remove everything. Looks like maybe screws on top side holding it down?
thanks in advance

How do I unlock the DVD Drive? I have the laptop disassembled to that point. Since there is no power, pushing the button on the DVD door does not pop open the DVD.
Thanks

Followed you procedure, any Ideas on what to do if the following keys; tab `56ty-=[], have stopped working afterwards. Should I just buy a new keyboard? or did I miss a plug somewhere? Everything else works as it should. Thanks for your help

@ Katie,
Try reconnecting the keyboard cable. Maybe the connection is bad. Make sure there is no dirt stuck in the connector.
