I have a Lenovo ThinkPad 7764CTO X61 laptop at my home. My laptop is working fine but it is giving me some troubles regarding the keyboard. I have observed that when my laptop wakes up from sleep, my keyboard does not function. I have tried pressing the caps lock button and num lock button but nothing actually happens. I have tried restarting my system but even this hasn’t helped me yet. Sometimes I have to restart and it works sometimes after the whole shutdown. Has anybody faced this issue? Any suggestions regarding this would be greatly appreciated. Thank you in advance.
