The notification from AVG requested to restart the laptop to update. I have been doing this every time the notification comes up but nothing wrong happened.
This time after restart, the password could not turn the laptop on and it keep showing the password was incorrect.
And it showed to reset the password from using the gold key disk, this laptop is a used one from my friend from Hong Kong. And I don't have the disk, what this could be solved?
