HP Pavilion g7 disassembly



In this guide I describe and demonstrate how to disassemble a HP Pavilion g7 series laptop.

My goal is to remove the motherboard and access the cooling fan which is mounted under the motherboard.

Make sure the computer is turned off before you start taking it apart.

STEP 1.

Unlock and remove the battery.

Remove laptop battery

STEP 2.

Unscrew two screws securing the service cover on the bottom.

Lift up and remove the service cover.

Loosen screws on service cover

Under the service cover you can access both memory modules, wireless card (removing in step 18) and hard drive.

Access memory hard drive

STEP 3.

Disconnect the hard drive cable from the motherboard. Pull it up by the black belt attached to the connector.

STEP 4.

Remove the hard drive. As you see, the hard drive cable still attached to the hard drive.

STEP 5.

Remove one screw securing the optical drive. Slide the optical drive to the left and remove it.

STEP 6.

Remove one screw securing the keyboard on the bottom.

STEP 7.

There are a few hidden latches securing the keyboard to the top cover.

In order to remove the keyboard it’s necessary to unlock these latches.

STEP 8.

Push on the latch with a small flat head screwdriver.

At the same time lift up the keyboard a little bit so the latch stays unlocked.

Do the same with all latches.

Release keyboard latches

STEP 9.

After all hidden latches unlocked, you should be able to lift up the top side of the keyboard.

Turn the keyboard upside down and place it on the palm rest.

Lift up keyboard

STEP 10.

Now you can access the keyboard cable which is connected to the motherboard.

In the following two steps I explain how to unlock the connector and release the cable.

Access keyboard cable

STEP 11.

Lift up the left side of the retaining tab with your fingernail.

The retaining tab will open up at a 90 degree angle.

Unlock keyboard connector

STEP 12.

Now you can pull the keyboard cable from the connector.

Disconnect keyboard cable

STEP 13.

Remove the keyboard.

If you are reading this guide in order to replace the keyboard, you can install a new keyboard at this point and assemble everything back together.

STEP 16.

Start separating the top cover (palm rest) assembly from the bottom case.

You can use a guitar pick for that.

After the top cover is removed you are ready for the motherboard removal.

But before you start, it’s necessary to disconnect and remove the wireless card which is mounted on the bottom of the laptop.

STEP 18.

In order to remove the wireless card it’s necessary to disconnect two antenna cables, remove one screw and pull the card from the slot.

Here’s how to disconnect the antenna cable. Simply pull it up by the gold connector and unsnap form the wireless card.

After both wireless antenna cables disconnected, remove the wireless card.

    do you have something that shows how to put hp pavilion g7 back together after disassembly

  2. IML Tech

    @ john angel,
    No I don’t. I assume you should be able to follow all disassembly steps in the reverse order.
    What is your laptop full model number g7-???. Probably I can link you to the official service manual.

  3. Thank you , thank you for Post this disassemble page GG ,HELP ME A LOT….GREAT…

  4. Priscilla

    Do you have a service manual for the Pavilion g7-1365dx?

  5. IML Tech

    @ Priscilla,
    For Pavilion g7-1365dx all disassembly steps should be the same as in this guide.
    If you need an official HP service manual, here it is.

    Thanks for this info. I couldn’t believe I had to rip my laptop apart to cleant the Fan/cooler system, but with this guide it worked quite OK.
    Had a great deal with removing the keyboard, since I cuoldnt figure how to get it out of the snaps without a bit of violence … :(

  7. I have a pavilion g7-1227nr There is a problem with the hp-101 webcam The problem is with the cable connecting to it I believe I was able to push it toward the camera and it worked for a minute or two. I repeated the process and now cyberlink can’t find the webcam any more.

    I suspect I damaged the cable and need to remove it Look pretty delicate in there. Do you have a tutorial set up for another model that would be similar?

    Plesae and thank you

    @ Raid,
    The web camera cable is part of the display cable.
    In order to replace the display cable you will have to remove the top cover assembly as it shown in this guide (step 17).
    After that you will have to take apart the display panel and remove the screen as it shown in this guide.

    When it’s done you should be able to disconnect the cable from the motherboard, remove it and replace with a new one.

    How to find a new cable? Look at the original cable. It should have a sticker with the part number. Search by the part number on eBay and probably you’ll find a replacement.

    Here’s HP’s service manual for g7. I though it could be helpful in some way.

    I removed the top cover assembly to clean my fan. I put it back on and my laptop will not turn on an now. Do you know what could have happened?
    Thank you

    @ Raquel,
    First of all, check RAM modules. Maybe the laptop will not start because of bad connection between the RAM and slot.

  11. Hi, thanks so much for this site it’s helped a lot of people, I have a question, do you know what the SM fuse rating is for (located by the power plug on the mobo)? Mine blew and the crack in the fuse makes it unreadable! I see something followed by 10y
    and then 1 V
    But that’s not really making sense…if I knew the proper current rating from the first line I’d be able to source it.

    Thanks!

    Many thanks for the guide! It was a great help. Clearly explained and perfectly illustrated. My cooling fan had cut out on me, and I got a thermal shutdown. Compressed air through the vents was no help. It turns out it was all due to the tiniest piece of linty gunk (or maybe it was gunky lint?) stuck in a corner of the fan housing where the air couldn’t reach. Thanks to you and this guide, I was able to get to that gunk, poke it out with a paper clip, and get back up and running in no time. Nice work! Cheers.

    @ Brian,
    Sorry cannot help you with that. I don’t have the motherboard schematics.

  14. Just wondering if the hp manual link you supplied here is for all/most G7’s. Mine is a G7-1310US, and every thing in the h10032 manual that you gave the link for seems about the same as mine. I got a message at last boot up saying the cooling fan was not operating. I ordered one from amazon at a cheap price. There were no reviews for any of the fans there so I am just taking a chance. I had removed all the screws, but did not know about popping out the keyboard to get at that hidden screw under it, but assumed it was indeed a screw holding the center down, so I put it all back together & booted it up. I have not gotten the cooling fan message during the last 2 boot ups, but I am sure it’s not running because I cannot hear it like I used to. Anyway, I did download a copy of the guide you gave & it is great! My new fan should be here in 2 days along with a tube of the heat sink transfer material, so I just wanted to make sure the guide does cover my exact model so I will be good to go when my fan gets here. Just another thought, do you have any recommendations as far as replacement batteries for these laptops? My G7 has an MU06 10.8v 4200 mAb battery that started dying very quickly at about 3 months old, so I have been using it while plugged into the power supply which kinda eliminates the portability. I have noticed a very big difference in battery prices and have been wondering why, & also researched what I could find on the batteries online which was not much. I was looking at a 10.8v 6600 mAb battery at a good price on amazon, so was just wondering your thoughts on batteries. Thanks for all the info you have published!

  15. Dumb question……what is the copper bar by the fan and can I replace it? Reason for question…..it gets extremely hot…..fan is very clean.

  16. Hi, the copper bar is the heat sink. It moves the heat from the CPU to the fan.

  17. Howdy. First of all, thanks for the great steps. I followed these to replace a malfunctioning fan in an HP laptop and now that I have everything back together the laptop will not recognize the battery. I have reset the BIOS and performed a battery check with HP’s support software but still nothing. The laptop works just fine when connected to AC power. Any ideas? Thanks again.

  18. Excellent web site, I look here often.
    I have a dead HP 15-e020ca. May have been hit with a power surge.
    The small SM component near where the power cable enters the board tests open with meter
    If this is the fuse where can it be purchased, shame to throw away the laptop for a .25 cent part.
    Any Ideas?

    I have a hp Pavilion g7-1316dx. I want to take the screen off and put a new one on. Mine is cracked. How do I get the screen off?

  20. Great website you have here! I was struggling for half an hour trying to figure out how to get the keyboard out and once I found this I popped it out easily and reading through the rest of the steps I was able to get past parts that I would have been stuck on forever because I had no idea they existed. Well done on such thorough pictures and of so many different models!

  21. Excellent write up! On my G7 dis-assembly I had one extra step for removing the top cover: once you lift up the top cover the speakers were still connected. From the left speaker you have to slide the red/black/white wires out of the white connector on the mother board behind the SD card reader. The red wire connecting the left and right speakers is taped to the base , and I just lifted the tape up and removed the entire right speaker. Once you have disconnected the speaker wires and un-taped the right speaker, the entire upper casing lifts right out.

  22. Thank you so much for the detailed step by step photos and detailed descriptions.
    I was having problems( well still am) with my laptop turning on and taking a charge. So being somewhat of a Electronics Tech; I tore the unit apart. tested voltages via battery and AC adapter the original parts/battery and the new replacement ones. Checked out the power adapter plug in and got a unload voltage 6.4vdc. SO my problems seem to point to the Motherboard. This unit didn’t even make it 18months. So I tried all of the suggested tricks from users and HP alike; no luck.
    I won’t ever buy or recommend HP products to anyone.
    thanks again for your info.
    Bless You
