No Display In Appear After Press Power Button
Hello, could anyone please help me.. My 4752Z can't turned on normally. The power indicator already on but no any display appear?
I search on google it may be caused by failure on BIOS. But I can't boot from USB Drive to start resetting BIOS due to no any display at all.
Any suggestion really achievable. Thanks :)
