In this guide I explain how to remove the keyboard and clean the cooling fan in an HP Compaq 6515b laptop. Most likely this guide will work for some other HP Compaq model. If it works for you, please mention the laptop model number in the comments below.
Also, you can use this guide for accessing and replacing the memory module installed in the hidden slot under the keyboard.
STEP 1.
Turn off the laptop and remove the battery.
Remove one screw securing the memory cover. Remove the cover.
STEP 2.
Loosen three screws securing the keyboard on the bottom of the laptop.
STEP 3.
There are four latches in the top row.
Unlock the latch by moving it towards the touch pad.
STEP 4.
Lift up the keyboard and place it upside down on the palm rest. It is not necessary to disconnect the keyboard from the motherboard.
You disconnect the keyboard only if you want to replace it with a new keyboard.
STEP 5.
The cooling fan is located in the top left corner.
If the cooling fan and heat sink are dusty, you can clean them using canned air or air compressor. Blow air inside the fan until all dust is gone.
Also, under the keyboard you can access the hidden memory slot and CMOS battery.

@ Autumn,
I think your friends are correct. Most likely this is heat related issue. Blow off the fan and see if this fixes the issue.

so here’s the question. i used my laptop (compaq) as usual to surf internet and play online games. there’s nothing problem when for web browsing. but when i turn on games, the screen suddenly turned black and after few seconds, laptop shutdown. it happened many times. so i asked friends bout it. they all said the same answer :” need to clean your cooling fan” . So yeah sir, is it true? if it is, i’ll open my lappy and clean the cooling fan lol

Did it with my HP Compaq 6715s. Didn’t have compressed air, just gave it some thorough whiffs (that almost left me with silicosis
, the fan’s noise went back to normal, yay! Will buy me a can of compressed air on Monday, though, it’s worth it certainly.

No need to pull them out which is a hassle (as I did). Just loosen them till the first resistance is gone.

Federico,
Take a look at this service manual for Compaq Presario F500 laptops: http://h10032.www1.hp.com/ctg/Manual/c01095493.pdf
The keyboard removal instructions shown on the page 40. It looks like all you have to do is remove three screws on the bottom.

I took out the bottom screws of my Presario F505 but still cannot take the keyboard out. It does not have latches to move. I removed battery and memory: should I also take out the HDD?

The fan gets its air from the bottom of the laptop (nx6110) and blows it through a heatsink. This heatsink collects all the dust and at last the dust will form an isolating blanket and your laptop runs too hot.
Blowing just air through the fan is not enough, unmount the fan and remove the dust from the heatsink (I used a vacuum cleaner).
Anyway, thanks for the instructions for opening my laptop! Its running smoothly again (Very silent and no display dropouts anymore)

Man you rock ! your instructions are so simple that even a kid can understand…… I was able to change the CMOS battery and my computer was up and running as new…….. Love you for this.
