Our office purchased 5 fujitsu computers in 2007, product model Esprimo Edition P2511. Of these 5, 3 of them are all experiencing the same problem.
During normal office work e.g. running MS Office 2003 ad outlook etc, the monitor display goes into sleep mode randomly and without warning. Displaying error 'No signal monitor going to sleep'
Once the monitor goes to sleep, no mouse movement or keyboard action will allow the displayt to resume. Also, the computer will not reset or turn off if you hold down the power button manually. The only way to switch off the computer is to unplug at the mains, wait a short while and plug in again. Clearly this is hugely frustrating as data is lost from the previous login, due to unexpected shutdown, and inability to save work once the display has been lost.
We have tried changing monitors and consequently the VGA cable, also different sockets and/or plug in the office
Since the problem is now arising on several of these machines, we would greatly appreciate some advice!
Thanks!
