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).

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.

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.

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?

Hi, are there multiple replacement fans for the G62 notebook? or do only the HP fans work?

@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.

@ 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.

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.

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.
