When you placed the top cover back on the notebook (you dismantled the PC to get to the RAM slots) did you remember to reconnect the ZIF connectors for the touchpad and the keyboard? Are the ZIF connector cables inserted correctly?
On page 45 of service manual you can see how to remove keyboard to take a look.
Hope it helps,

Yes , I have assembled the laptop by taking care of each and every cable and put it in right place.
And after the very 1st boot of my laptop my keyboard was working fine but when after a few hours later when i turned off and then on the laptop none of trackpad or keyboard were working fine.
Keyboard registered some abnormal strokes.
After that I agian dissembled the keyboard and track pad and again reconnected it. But no luck.
Do you know any software releted fixes as when i googled on guy having mac had same problem but was able to fix it with some software alterations here's the link https://www.tonymacx86.com/threads/solved-keyboard-and-touchpad-stopped-working-after-ram-upgrade.17...
Thanks for considering my problem.
