I am puzzled by a problem that could be the monitor, the on-board video or something else:
Lenovo ThinkCentre Desktop (8212)
Samsung 930B Monitor and Windows XP
On turning on the monitor and computer, the Windows startup sound can be heard, fans work, hard drive works, no beeps; but the monitor remains dark with a blinking green light.
My first thought was that the monitor had a hardware problem.
I did a search and no video plus blinking green light seems to mean "unable to get out of sleep mode due to power supply failure".
I disconnected the monitor from the computer (video cable) and turned both devices on.
The computer booted up without errors and got the Windows startup sound and no beeps.
The monitor started up and at least it showed the "no signal" image moving around on the screen and a steady green light.
However, the moment the monitor was connected to the video port on the computer, the screen went black and the light back to a blinking green light.
I'm guessing the monitor needs replacing, or the on-board video is dead, but not certain of either.
The user is going to test the monitor with anothe computer tomorrow and the computer with another monitor to see if anything shows up.
Any ideas or suggestions would be appreciated.
If the on-board video is dead, will using a video card by-pass the on-board video?
