Keyboard Removal, this is a bit tricky………..
– There are 4 very small tabs or clips above:
“Delete, F12, F8, and F4″ Keys
Look close above these keys, push these VERY small tabs/clips up and in towards screen. These clips lock keyboard down in place. Start with the “Delete” tab and work towards the left “F4″ key tab.
The next tricky part is getting the keyboard to pop up and out enough to grab and pull up from right to left.
Pull the top of keyboard up slowly, be careful there is a ribbon cable that connects keyboard to motherboard.
There are small snap clips on the left & right side of keyboard, but these do not push in, keyboard just snaps out of these on the side
2 small black tabs, carefully gently push tabs out a bit to unlock the keyboard ribbon cable.
Black lock bar tabs push towards front of laptop, slowly! You break these off then we have other issues.
