My back lights on the keyboard and my power button light(s) all stopped working at the same time.
I know my laptop is old...but, there has to be an easy fix to this issue. I assume it happened when a Windows 10 update was automatically installed. So, I tried to restore to an earlier date, and it didn't UN-DO it. Any other ideas?
I think I remember the same thing happened when Windows 10 FIRST CAME OUT, and Sony Tech support helped me through it. Now, the phone number I used before just has a recording, saying they don't help guys like me anymore.
You may still try my suggestions below and see if the issues will be resolved:
Power cycle - Shut it down, unplug all connected devices especially the AC power adapter. Using a safety pin, hold the battery off button for 5 seconds located on the bottom of the unit. Connect the AC power adapter and turn it on again.
