I have an IBM Thinkpad model R51. I use it for my work and have a strange issue when resuming from stand-by mode. The problem is not consequent it happens sometimes after two stand-by / resume actions but it can also take a week for the problem to occur. All lights below the screen turn on normally and you can see the HDD light blink, but no screen to see what you are doing :(
The only solution is to hold the power button and to resume with a cold boot which takes ages with this machine by the way.
The R51 has Windows XP pro fully patched with service pack 2 and all security patches loaded.
Hibernation is turned off
No application or system messages occur in the event viewer after the event.
My colleague has the same issue with his R51 no solution found so far.
Hope you guys can help.
