I have a Probook 6360b that does not display anything on the LCD. The LCD is lit, but there is no picture. There is a display when I connect the laptop to a monitor (VGA).
I have done the following to diagnose the issue:
-Tried a known working LCD from a "retired" 6360b - that didn't work in this computer
-updated the BIOS
- deleted the video driver, reinstalled, updated etc.
- did a hard reset of the system
-the hard drive works in another 6360b
-a known working hard drive from another 6360b does not display on the LCD either.
I can't get into the BIOS or diagnostic tests because by the time the laptop recognizes the external monitor, it is already on the log in screen.
I'm afraid it is the motherboard that is the issue. Any other suggestions are appreciated!
