Hi,
I have an issue which is effecting multiple sites and multiple dell optiplex models.
All was working well until about 4 months ago. Teachers would come into school in the morning and the green power button would be lit up, the dvd drive can be ejected, but there is no display. Pushing the power button does not bring it out of a hibernate\standby state. The only way to get the computer to boot up is to do a dirty shutdown. However there are no event logs saying that there was a dirty shutdown.
I have tried:
updating bios firmware
updating video drivers
setting shutdown/wakeup schedules.
Full windows update
Removed all power management settings.
BIOS config has not changed.
Has anyone else come across this issue or have any advise on what direction I should be heading towards.
Thanks,
Warren
