In this guide I explain how to disassemble a HP G62 or Compaq Presario CQ62 laptop.
I believe that HP G62 and Compaq Presario CQ62 are very similar laptops (if not completely identical). HP has same service manual for both models.
Before you start, make sure the laptop is turned off and battery removed. Let’s take it apart.
STEP 1.
Loosen five screws securing the hard drive and memory covers. Remove both covers.
STEP 2.
Remove three screws securing the hard drive assembly.
The left screw (yellow) also securing the DVD drive.
By the way, both memory modules can be accessed on the bottom of the laptop.
STEP 3.
Lift up the hard drive assembly.
Disconnect hard drive cable from the motherboard.
Remove the hard drive assembly.
STEP 4.
Pull DVD drive from the laptop and remove it.
STEP 5.
Remove six screws securing the keyboard on the bottom of the laptop.
STEP 6.
In order to remove the keyboard, you’ll have to push it through the opening near the wireless card.
You can use a pen or any other stick.
STEP 7.
While pushing on the keyboard through the opening by the wireless card, grab the top side somewhere in the middle and lift it up.
STEP 8.
Turn the keyboard over and place face down on the palm rest.
STEP 9.
Now you can access the keyboard cable connector.
Before you can remove the keyboard, you’ll have to unlock the connector and release the cable.
STEP 10.
Here’ how to unlock the keyboard connector.
Lift up the brown tab with your fingernail. The tab opens up at a 90 degree angle.
STEP 11.
On the following photo the connector shown in the unlocked position.
Now you can release the keyboard cable.
STEP 12.
Remove the keyboard.
If you need a new keyboard for HP G62 or Compaq Presario CQ62 laptop, you can find it here.
STEP 13.
Remove all marked screws from the bottom of the laptop.
These screws securing the top cover assembly.
STEP 14.
Remove one screw securing the top cover.
Disconnect four cables from the motherboard.
STEP 15.
Unlock the touch pad cable connector same you unlocked the keyboard connector.
STEP 16.
After the connector unlocked, pull the cable from the connector.
STEP 17.
Separate the top cover assembly from the bottom assembly.
Continue removing the top cover assembly with your fingers.
STEP 18.
Remove the top cover assembly.
STEP 19.
In order to remove the display panel, you’ll have to disconnect both antenna cables from the wireless card.
Also, you can remove the wireless card. Simply remove one screw securing the card and pull it from the slot.
STEP 20.
Disconnect display cables from the motherboard.
Remove four screws securing display hinges.
STEP 21.
Lift up and remove the display panel.
In the next guides I’ll explain how to take apart the display panel and remove the LCD screen.
STEP 22.
Disconnect two cables from the motherboard.
Remove three screws securing the motherboard.
STEP 23.
Start removing the motherboard as it shown on the following picture.
STEP 24.
Lift up and remove the motherboard.
STEP 25.
On the other side of the motherboard and you access the cooling module (cooling fan and heatsink) and CMOS battery.
Now you can clean up the cooling module or replace the fan if it failed.
New or used replacement fans for HP G62 and Compaq Presario CQ62 laptops available here.
STEP 26.
The DC jack is not soldered to the motherboard. It’s attached to the harness which can be unplugged from the motherboard.
If your DC jack failed, simply disconnect the failed harness and replace it with a new DC jack harness (again, it should be same part for both HP G62 and Compaq Presario CQ62 laptops).

Great article, thanks

Would you have a step-by-step images of disassembly of HP G60 series 530US Notebook? I need to change a DC jack and determine if it was or needs soddering.
May 1st, 2011 at 10:02 pm
hi i have 2 laptops, ibm g40 and hp g62 b31, if i remove the dvd for the hp and put it in ibm will it work?
May 3rd, 2011 at 1:16 pm
i have problem when i try to clean cooling fan from inside i made everything like here but when i put all together, the “i” “k” “,” and “8″ dont work, the same is with quick launch buttons… Do you know what i screwed up? Sorry for eng.
May 3rd, 2011 at 3:49 pm
Richardo,
Take a look at this guide:
http://www.insidemylaptop.com/remove-replace-damaged-lcd-screen-hp-g50-g60-g70-notebook/
The guide explains how to remove keyboard and display cover. After that it’s not hard to remove to top cover assembly.
Also, at the end of the guide you’ll find links to laptop service manuals with disassembly instructions.
May 3rd, 2011 at 3:50 pm
elie,
Most likely the drive will not work or even will not fit.
IBM laptops use preparatory parts designed for IBM laptops.
May 3rd, 2011 at 3:52 pm
angelus,
If the keyboard worked before and stopped working after disassembly, I think the problem could be related to bad connection between the keyboard cable and motherboard.
Try reconnecting the keyboard cable on the motherboard. Make sure the keyboard cable is clean and there is no dirt inside the connector.
May 4th, 2011 at 2:38 pm
i made everything again but is still don’t work, i clean cable and connector but no result, im little bit nervous because i dont wanna buy a new keyboard, any ideas?
May 9th, 2011 at 5:53 am
Such a Great Article. it solves my problem, thanks…………

June 4th, 2011 at 7:42 pm
I was given a Compaq Presario CQ62 from a friend as a gift, it’s used btw. Are there different models of this same laptop? And if I wanted to replace, say the heatsink will one that says it’s for CQ62 work for all CQ62 models if that’s the case? I’ve also been wanting to replace the processor with an AMD Phenom 2 N620 or N660. The processor that’s in this machine now is an AMD V120, so will the CQ62 be able to run a 35w processor if my current one is 25w? Also, if I just want to change the processor do I absolutely have to take off the screen? One last thing, is the graphics card for this machine changeable too?
June 5th, 2011 at 8:13 am
@ Joseph,
There are different models in CQ62 line but they are very similar. I guess the main difference will be amount of installed RAM, size and maybe speed of the hard drive, speed of the processor.
There are different fans. They are listed in this service manual for Compaq Presario CQ62 notebooks. You’ll have to figure out which model you have and which fan to use.
Don’t know. There are lots of different AMD processors listed in the same service manual on the page 23.
Yes, you’ll have to disassemble the whole thing and remove the motherboard.
I don’t think so. I believe the graphics card built into the motherboard.
June 5th, 2011 at 7:35 pm
Thank you very much for the help, I appreciate it a lot.
July 2nd, 2011 at 2:26 pm
Nice demo! Wish there was an easier way to get to the fan.
July 6th, 2011 at 10:16 am
first of all, great tutorial
is there any way to install LEDs under the keyboard and put some sort of power supply in the case
if there is a method, how much money it would cost, maybe you can make tutorial about that it would be appreciated
July 6th, 2011 at 2:39 pm
Hi tanxs for the blog. I have one question. I have hp g62 notebook and the screen turn off randomely when i touch it in the back(screen back) it turns on. pls tell me the problem. Is it the video cable problem? Thank u.
July 25th, 2011 at 5:06 am
nice , but i have cq70
August 9th, 2011 at 9:21 pm
Wow, Thanks a lot!!
This helped so much!!!
August 13th, 2011 at 11:54 am
Thanks, I’ve taken a lot of laptops apart but this one was different than most. Had to look it up to figure out how to get the keyboard out without breaking something. As usual the heat sink was completely clogged up. You’d think laptop manufacturers would address this issue. If not a complete redesign at least make it easier to access and clean.
August 23rd, 2011 at 7:40 pm
Hi,
Thanks for the clear procedure to fix my laptop. I owe you.

Thank you this helped a lot with screen repair of g62
much appreciated
August 30th, 2011 at 1:25 pm
just wanted to let you know that your tutorial enabled me to fix my G62 laptop (cooling fan took a dump)…i would have NEVER attempted this fix (even though i have built, serviced and upgraded MANY desktop computers over the years) without the guidance from this excellent article.
amazing how simple laptops really are….you just have to be extra careful with the connectors and label the screws as you take them out….other than that, they really are very similar to desktop computers.
thank you again for your tutorial…it was spot on!
September 10th, 2011 at 11:34 am
Hi
Looks like a great article, I have a big concern before trying to clean out the fan though. You say pull out DVD drawer and remove. It doesn’t seem to be that straight forward to me, for example there is a tape that runs inside preventing coming out too far. Can you tell me how to remove the DVD drawer please, or anyone on the site who has done this.
thanks
September 12th, 2011 at 9:06 am
Hi
After the disassembly of my HP G62 120-EG with without a tutorial i was looking for someone who made one. I had a plastic piece in my fan which made a nice clattering sound. Otherwise i would made one. So here it is a great tutorial, detailed, illustrated and with all difficulties this disassembly had.
newertheless thanks
September 13th, 2011 at 10:00 am
hakns .. look like cooling fan is a big problem for hp , not only this model bot many of hp’s machine :/
Y-not
September 18th, 2011 at 12:05 am
Hi, tried too follow this guide in order to disassemble my laptop.
I found one huge problem though, there is pretty much no way I can remove my motherboard like that without breaking it, it just seems to require way too much force.
Anyone can give some additional tips on how to remove the mobo?
September 24th, 2011 at 5:11 am
Hi,
I follow the above mentioned step however I’ve successfully Re-Assembled my Laptop.
Thanks
September 27th, 2011 at 8:10 pm
can someone tell me on hp G62 what could caused
the burn of the resistance pc522 on the back of the
fan 5 cm on the right is the first from top , in the same
place on front is an high voltage bridge IR0. the
problem is what could cause this ? overheat? Bad
tension administration? someone can help to know if
worth to change the resistance or not.
September 28th, 2011 at 9:28 pm
I was interested in converting Laptop to digital photo frame. But I was facing trouble in dismentling the laptop. this article will help me very much. I am very much thankfull to you.
October 2nd, 2011 at 8:04 am
Charles,
The reason you cannot remove the mother board is because you have to detach the wireless card shown above. I made that mistake too.
October 24th, 2011 at 4:57 am
Hi, thanks for the article, was a definite help in changing my girlfriends busted DC jack.
Was an HP G62, but there seemed to be some differences in screw placements, and I think there were a few more screws in the machine I opened up, but it wasn’t difficult to work out what to do!
Thanks again for the article, saved about $150!

this was incredibly helpful as my lappy kept having issues in this heat… it gets heaps hotter than it should running simple programs. and as such becomes a issue with burning things.
just got compaq’s back up junk to do now lol
anyhow the the hdd had a bit of a failure and as im useto desktops i had no idea where to begin… all sort of working now
November 18th, 2011 at 3:56 pm
I found this a great help in fixing the fan in my HP. It was noisy and not moving much air. We dismantled it and cleaned it out and everything seems to be working great. I couldn’t have taken it apart without these instructions. These seems to be built so you have to take it to a service tech, or risk breaking something!
February 19th, 2012 at 9:09 am
Thank you. This was very helpful to me. I needed to be sure that my cooling fan was good and cleaned. I was abled to clean the dust out of there good.
March 4th, 2012 at 6:48 am
great dis assembly guide man. thanks
March 18th, 2012 at 10:57 am
ty man….
saved my daughters laptop…… a pad of dust was blocking the cooling vents……
Now it over heats no more cheers
March 20th, 2012 at 7:50 am
Love you !
March 29th, 2012 at 11:03 am
This is a great guide my cq62 is getting hot and I need to put some artic silver on that cpu, the gpu, and clean the fan.
I wish it was a little easier but it has to be done.
April 19th, 2012 at 11:56 pm
Hi everyone..pls can someone tell me my g61 just stoppped working ..when i plug my dc in the fan spins but nothing els happens and my wireless led stays on anyone pls help me???
April 23rd, 2012 at 4:55 pm
thank you for the step by step. helped to get wife’s HP apart unfortinately
I guess during assy they stripped the head on the screw holding wireless card
so I can’t remove mb to grease the the heat sink on prosesser thank you hp
May 5th, 2012 at 10:52 pm
is there anyway to remove the fan from the heat sink or are they made together?
May 10th, 2012 at 9:44 am
You sir are a life saver! I downloaded the service manule from HP and it was full of errors. This made life a whole lot easier.
May 13th, 2012 at 10:39 am
You are impossible, God bless you real good, so accurate you just safe a life.
May 15th, 2012 at 3:35 am
Hi my friend, I have the problem for hp 530 which is not display, I tried to change th ram but I was not success in case that I need your idea
thank u
May 18th, 2012 at 6:48 am
Hi there,
Indeed this is a fantastic guide. My G62 usually stops due to overheat and i manage to clean the dust inside.
However i made a mistake. When removing the keyboard connector i forgot to lift the holder and broke it, im afraid. No surprises, after putting all together, my keyboard doesnt work anymore.
Still it’s well secured and connected to the junction, but does the lift forces the connector to work?
Is there any way i can go around this issue?
Thanks in advance.
May 18th, 2012 at 10:02 am
@ Michael,
Why do you think the connector is broken? It sounds like the holder still connected to the connector.
Try reconnecting the cable. Make sure it’s seated correctly, all the way into the connector.
May 22nd, 2012 at 6:11 am
@Laptop Tech
Thx for the quick reply. Since im now carrying a wireless keyboard, i tried the laptop keys today and discovered they do work, not all but some.
About the lift and the connector, you see the image from step 11? the black piece you lift with your nail, is broken in my case. The cable is suited all the way, even put some tape to hold it in place.
However cant figure out a solution for it.
Many thanks for your attention on backing me up. Much apreciated.
June 11th, 2012 at 7:00 pm
Hi, are there multiple replacement fans for the G62 notebook? or do only the HP fans work?
June 14th, 2012 at 3:03 pm
Hi why is it when I lift the lid on my HP G62 I have to move it back and forth in order tor the picture to show up?
June 20th, 2012 at 6:10 am
how does the LCD turn off when you close the lid on a G62? is there a lid switch or does the left hinge contact the mother board? i replaced the lcd and can only get it to work when the lid is 3/4 closed. before i buy a new video cable i was looking for a switch to test.
June 30th, 2012 at 1:05 pm
Sorry to bother you but i have a question: On my G62 looks like the HDMI port broke off finally it is still there of course but no connection any more / last few months i had to “wiggle’ to make it work / the HDMI cable is too heavy and pulls the port downward so even with a little support under the connector is no connection now so it is phisically broken. So how can i fix this? Could you advise please? Thank you for your time.
July 1st, 2012 at 10:51 am
@ andy,
The HDMI port is soldered to the motherboard. It’s necessary to disassemble the laptop and take a closer look at the port. Maybe resoldering the port will fix it.
July 17th, 2012 at 7:29 pm
I followed your great set of instructions and came to Step.20 (Disconnect display cables from the motherboard.). When I tried to disconnect the very last cable (bottom left on your photo) – I pulled tinny wires out of their plastic connector
The dimensions of the connector does not give me any confidence that I could solder two things together – is there any way to do it or even buy the cable and replace the one with the broken end?
Thank you for your help,
Mladen
July 18th, 2012 at 9:56 am
@ Maden,
I don’t remember what kind of connector it is. Look inside the connector. Can you see pins inside? Is it possible to connect wires directly to those pins?
I believe this is the microphone cable and it’s available here.
July 24th, 2012 at 9:20 am
Thank you for an advice. The end connector of G62 microphone mic cable looks exactly the one I damaged during the procedure.
Regards,
Mladen

Hi, I am trying to fix my Compaq CQ62, but i’m not 100% sure what I need. I am presuming the fault is with the left hinge, which seems to have either broken, or come loose somehow. This is causing the base to come apart at the top, left hand area, above the keyboard and a small corner shaped part has come out. The top part of the laptop base is now lifting up in that area & some of the keys don’t work. I don’t know which tutorial to follow and which part I need so could you please let me know what you suggest for this problem? Thank you very much.
August 1st, 2012 at 5:48 pm
@ Michelle,
There is no way I can tell what’s going on without taking it apart.
It’s necessary to remove the top cover assembly as it shown on the step 18 and take a closer look inside.
Maybe hinge screws shown in the step 20 are loose.
August 1st, 2012 at 11:52 pm
Can i use this disassembling process for HP G42 ? I think it is similar to this one….. Please Reply….
August 2nd, 2012 at 9:55 am
@ HanishGC,
This will be one of the next guides. I already took pictures while taking apart a HP G42 laptop. Now I have to compile them into a guide.
August 3rd, 2012 at 1:36 am
thanks man for the reply…… but can u make the guide fast……… i m facing the overheat problem so i would be better for me if u do it fast…….. anyway thanks again…
August 3rd, 2012 at 8:29 pm
I need to replace my keyboard, I am also not a big fan of the stock keyboard that this model comes withg, are there other keyboards that will fit and configure properly? Please reply.

Fan Replacement – First off, THANKYOU for this indepth guide. I’m going to provide a little more detail about my fan problem and replacing the fan to help other readers:
My G62 fan was not coming on and I was getting the fan error 90B during start up. I had already cleaned out the fan area by lifting the keyboard (steps 1-8) and blowing air into it which had a large amount of dust. This allowed the fan to work on but it did not always start after pressing the power button. I used the ebay link step 25 and ordered from seller ny-citi-com for $11 with shipping and it got to me in 4 days. (Note, it included the thermal paste for the processor)
I followed the guide above, but I did not need to remove the display panel. On step 20, I removed the cables but I did NOT remove the screws for the hinges. I skipped step 21 but did the remaining steps through 25. The only thing you have to look for is on the left side hinge for the display there is a tab that sits on top of the Mother board but you can still get it out.
To remove the old fan, unscrew the 4 spring screws on top of the processor so that the heatsink holder is freed up. Unplug the fan wire. The fan and fan housing is simlpy stuck to the mother board with very strong tape. I used a very small flat blad screw driver and rotated it side by side until it popped loose. I did this on the top edge of the mother next to the video port. Look at the top right of the picture on step 25. The fan, fan housing, and heatsink are now free of the mother board. Now unscrew the 4 tiny screws that hold the fan to the fan housing (the houseing is a very then piece of metal that closes up the top side of the fan and is connected to the side vent and head sink. The bottom of the fan is shown in picture 25). Screw the new fan on.
I meantioned before, that the fan vendor sent me the gray thermal paste for the processors so I cleaned the old paste off the processors and the heatsink holder. If you don’t have this, just leave orignal on there. I put a small drop on each processor chip, lined up the screws and screwed it down using a crossing pattern to ensure it was on snuggly. Now put it all back together in the opposite order.
Again, Thanks for this great article.
September 15th, 2012 at 8:57 pm
Thanks so much for this guide!
Started off wanting to replace the fan on my G62-340US but didn’t realize it was all the way at the bottom! After getting down there decided to upgrade to a Phenom II as well and my computer is running like a champ! This guide made it quick and easy, so hat’s off to you.
Once again, thanks!
September 20th, 2012 at 10:52 am
Can this work for my HP Pavilion DV6t SE
Please help i’m having a problem ” system fan 90B” Will the above steps work for my laptop?
Thanks
September 21st, 2012 at 9:56 am
I followed all of these instructions to the T, I replaced the fan and housing unit, and now my fan starts every time I turn the laptop on, but when I try to play video games or play a large MKV movie file my laptop abruptly shuts off. Before, my laptop would get too hot and it would slowly shut down since the fan wasn’t working properly… could i have reassembled something wrong? did I screw the heatsink back on too tight or too loose? Maybe I need to replace the thermal paste? Please help!
November 29th, 2012 at 6:02 am
hey, i have compaq cq62 (i5 , 4GB,…).
does this laptop has any graphics card slot.
and if yes then where is located ,with respect to above pics.
November 29th, 2012 at 1:52 pm
@ anonymous,
No, it doesn’t have it.
December 2nd, 2012 at 7:32 am
while removing keboard,keyboad connector was damged,how to replace that….
December 5th, 2012 at 7:44 am
Thanks for the guide. Dust bunnies accumulated in my fan, prompting thermal shutdown. I opened up the fan, removed the bunnies, cleaned off old thermal paste and applied new stuff. Yay!
December 21st, 2012 at 8:21 am
SHOULD MAKE A GUIDE ON HOW TO DISAMBLE THE BATTERY PACK, ONE CELL IN MINE IS DEAD AND I DONT HAVE THE MONEY TO REPLACE THE ENTIRE PACK.
WOULD DONATE FOR SHURE.

December 30th, 2012 at 6:01 pm
Have just pulled apart laptop to clean out CPU fan and replace the thermal paste. It used to get hot and slow down when being used for a while or doing some real work. Sure enough quite a bit of dust clogging up the fins.
Used isopropyl to clean, Arctic Silver 5 paste. Checked HSF mounting, all connections etc..
Started up, loaded into windows no probs. Restarted it and loaded into bios but it shut down a few seconds later. Now when trying to restart it gives overheating warning from previous shut down and shuts down 5-10 seconds later.
I’m confident its all back together fine, CPU fan is working.
I read Arctic silver takes a while to reach optimum efficiency but only a few degrees. One thing they recommend is slightly rotating the HSF but you can’t do that in this case. Might pull it apart and check the HSF and cpu have made good contact but im sure they will.
What else could’ve gone wrong here?
January 1st, 2013 at 4:59 pm
I want to try replacing the fuse, because my g62 computer will not power on nor will it light when plugged in. Is that the fuse or is it the motherboard? Where is the fuse?
January 4th, 2013 at 3:42 pm
Have resolved the issue now.
It turns out that the factory thermal pad is quite thick for the graphics chip. When you replace this with thermal paste, the heatsink barely touches the graphics chip. It looks like it is making full contact once on, but I removed the heatsink again and only a small amount of thermal paste had contacted the heatsink. The CPU was making great contact with its part of the heatsink.
So I applied more thermal paste (more than arctic silver recommends) and attached the heatsink, screwing down the CPU screws tightly first, then tightening the screws for the graphics part of the heatsink. This will make the most contact possible with the graphics chip, I hope.
This seems to have worked. Has been running for a few days now with no issues.
Is there a way to monitor the temp of the Ati HD 545v chip? Installed Open Hardware Monitor and it gives graphics voltage and clock speeds but not temp.
January 4th, 2013 at 3:53 pm
@ James,
Have you confirmed the external power supply is working? An electrical appliance store can easily test it. Takes one minute with a multimeter.
If that is working, next thing to try is step 26, replace the DC jack.
Check those two things first
January 16th, 2013 at 1:26 pm
hello and thanks for suplying us an excellent job!!! i have a g62 hp laptop -135EV
can i upgrade the processor from intel core i3 to i7? and if yes how
thanks a lot!!!!
January 23rd, 2013 at 4:51 am
Nice procedure. According to the skimpy HP docs I read to replace my optical drive you remove hard drive which I did. then I read there is a release for the optical drive that you access with a screwdriver. Your procedure says to pull out the optical drive after removing the 3 hard drive screws. What secures the optical drive in the laptop? thanks
January 23rd, 2013 at 11:57 pm
Just got done with your guide, and the problem with my girlfriend’s cooling fan is completely fixed.
You rock and HELL YEAHHHH!!!
[been a problem for 8 months.]
January 29th, 2013 at 4:59 pm
@James Did replacing the DC jack work?
I am having same problem with my CQ62, it will not power up at all. When AC Adapter is first plugged in LED is orange/red then goes to solid white but pushing the power button does nothing.
Anyone have any ideas?

February 5th, 2013 at 6:02 pm
@ Brandon,
These are wireless antenna cables. You disconnected them from the wireless card in the step 19.
February 22nd, 2013 at 10:43 am
Hello, thanks for all hard work.
Question is, on this motherboard, here is power fuse?? cant find hem, is near to white power connector on motherboard, is the brown one??

Hi I replaced a bad motherboard (with hp replacement). The laptop turns on now, however, the screen is fuzzy and at start up there is a red vertical line that appears about 4 inches from the right side of the screen. It then goes away, however, all the colors are a bit off and blurry. Like what ever is supposed to be white, it now a bright blueish green color. Can you please help?

Presario-CQ62 that is 2 1/2 years old. Had a 2 year extended warranty. Did not use the computer until the last 5 months. I noticed one day when turning on with the on/off button it didn’t seem to want to turn on. Then about a week later…it just won’t come on. I took it to Best Buy, they tested the power cord (it was fine) and they removed the battery to power with cord (wouldn’t power up). So…I am seeing it is probably the mother board. I am seeing some reference to a fuse replacement in inquiries. Is that inside the laptop? Any other thoughts? It never heated up. It is stored when not in use in a case. Just, stopped powering up. Is it possible the on/off button is no good? Why is it, when I buy a warranty the product always becomes junk within 6 months of the expiration? Bummed severely.

@ Teresa,
Remove the laptop battery. Plug in the AC adapter. Can you see any LED light on the laptop when the AC adapter plugged in?
There is a change you have a problem with the AC adapter. When you test voltage on the AC adapter without connecting it to the laptop it’s not always accurate. There is a change the AC adapter shows correct voltage when not loaded but when it plugged in the laptop (loaded) it fails to provide the required voltage. In short, before doing anything with the motherboard I would test the laptop with another known good AC adapter. If the laptop doesn’t work with another adapter most likely the motherboard failed.
Yes, it’s possible. If the laptop shows lights when the AC adapter plugged in but doesn’t turn on there is a chance of failed power button board.
This board is mounted to the bottom side of the top cover.
In order to replace the power button board you’ll have to remove the top cover assembly as it shown in this HP CQ62 disassembly guide in step 18. Remove the top cover, remove the power button board and replace it with a new board.

Hi there,
I’ve successfully disassembled the top cover, and replaced the DC jack. Need a new power button ribbon (tech seems to have broken the original one), but I’m having trouble attaching the touchpad ribbon cables to the motherboard. The little offwhite connector ‘locks’ came off, and it’s not obvious how to get them to stay back on. Also, it’s not clear whether the ribbon cables go on top of the pins, or beneath them.
Can anyone help?
