Trackpad and keyboard not working
Out of the blue, my laptop’s internal keyboard and trackpad have stopped working. However, I can still use an external mouse and keyboard without issue. Nothing really happened. Opened the laptop one day, and it was unresponsive other than the power button. I have tried all the software resets and have also replaced the battery, since other posts on this website suggested that battery expansion might be an issue. (It was well over 1000 cycles anyways). However, the problem still persists.
Posting couple pictures of the internals below. Any help in diagnosing the problem would be greatly appreciated.
Thanks!
