I booted up my machine today. The keyboard blinked once and then all lights off. Then it shows "... keyboard error / keyboard not found, press F1 to continue or DEL to enter Setup. I tried to replug my keyboard, but it has no response. Then I reset the machine and this phenomenon appeared again. Then I tried to connect another keyboard, It also appeared the same. What happen?
Just now, I could turn on the computer (keyboard detected) but all keys are not functional. But the mouse works in Windows and there is no problem to detect keyboard in "control panel - keyboard".
I have turned off the machine now.
I think there is no problem for the socket as it blinked once. It means there is no problem for the contact.
