Hi…
I am * Super*!!!.
My problem is Laptop screen went to Black while working and after that I shut it down and restarted it, it sounds 8 beep sounds while switching On. I’ve some work experience on computer Hardware. I wanted to know which may be the possible root cause for this problem. From internet I got two testing options to find the cause of this problem
1.LCD Screen Failure Test: Connect to External monitor, if extn monitor works then Laptop screen is failure
2.LCD connector Problem: LCD (Built In Self Test ).Holding D and Power button.. It should some soild colours like red,green,etc. connector is good
Questions:
- Is there any other test to find cause off the problem ?
- Above tests and way of finding is correct ?
- If external monitors works and reseting BIOS will my laptop monitors work as lastly?
Waiting for your reply.
Thanks in Advance.
