Turn off the laptop and remove the battery.
-
Remove two screws securing the Keyboard.
-
The Keyboard is held by two locking clips, under the battery. Use the sharp tip of a plastic tool to release the keyboard.
-
-
-
Remove the Keyboard and disconnect the two flex cables:
-
Keyboard flex cable
-
Keyboard Light flex cable
It would be helpful to have more info on how to remove the two cables. The larger one has a couple of clips that slide, but what exactly comes off? Do the plastic strips lift, or do the flat cables just pull out of them? Don't want to break something!
I watched several videos, many of which had the action hidden behind the keyboard. The larger ribbon pulls out of the strip after the two white clips on the end are moved. The smaller one has a black strip which lifts from the ribbon side, releasing the cable.

Remove the screw securing the Optical drive and gently press the drive to show slightly as at the second pic.
-
Slide the drive to the left and remove it.

-
Remove 4x phillips screws and disconnect:
-
Power On button flex cable
-
Touch pad flex cable
-
Remove 18x Phillips screws from the bottom cover.
-
Remove any memory SD Card from the Card reader.
-
Start opening with a plastic opening tool.
After removing the 18x Phillips screws, the laptop is VERY fragile in the hinge area. The bottom cover will easily crack or break in the hinge area when opening the laptop with no screws, particularly the left side near the power button. Possibly this step should be revised to recommend opening the laptop 90 degrees before removing the 18x screws. Or, advise extreme caution when opening the laptop with no screws.
Hi, do you know where buy screws that you mention in step 4? “Remove 18x Phillips screws from the bottom cover.”
I am italian. Thank you anyway.
The laptop I have included 6x screws from inside and 16x screws from the bottom. This seems to be a minor variation from model to model.
Same with my model @sara Caruso. The six of them, and the two to release the keyboard, are shorter than the 18. All the screws had blue locktite on them.

Perfect! Thank you for the instructions. Thought I'd bricked my laptop, but I followed your instructions and left the battery out for 5 mins. Re-assembled and it's as good as new.
The two clips push toward the space-bar part of the keyboard. There are further clips around the edge of the keyboard, but it can be removed by careful prying with a thin blade screwdriver.
