If you need replacement parts, you can find them here. Just search by the part name and laptop model.

STEP 6.

Carefully lift up the keyboard as it shown on the picture below.

STEP 7.

Access the keyboard cable connector underneath the keyboard.

Unlock the connector before removing the keyboard.



In order to unlock the connector you’ll have to move the locking clip (white) about 2-3 millimeters towards the LCD screen.

The locking clip must stat attached to the connector base (dark brown) as it shown on the picture below.

Now you can release the cable and remove the keyboard.

@ DealeX: I used copper shims for both the CPU and GPU and I bought them off ebay. Their size is 20 mm x 20 mm x 1.2 mm.

BTW I encourage everybody who was helped by this website to donate a bit as I did.

236DealeX Says: May 11th, 2012 at 8:10 am

@Reem and Laptop Tech: Can you tell me which copper shim i can use (for the GPU)? Cause i “refurbished” my notebook andthe CPU got much cooler. However i didn’t knew how thick the new cooling pad for the gpu should be. My local dealer said,there are several pads with different thicknesses and it’s important to choose the right one! So how thick should it be?Respectively how thick should be the copper shim?

Obviously i choose the wrong thickness, cause the GPU temperature now rises very quickly when i watch movies

The 4 screws that secure the display hinges to the display enclosure are Phillips PM2.5X7.0 screws.

Great tips!

Have just one problem. Got a CQ50-112EO and after repairing it just can’t seem to find the 4 screws that affix the screen hinges.Could somebody give me their size and details so I could look them up and buy them, please?
