Monitor not getting signal until restart

mhmed009 · Aug 28, 2014

so basicly sometimes when i leave my PC for sometime and reopen the monitor it stays on standby without getting any signal from the PC , all Fans/lights aswellas the DVD-Drive in the case are working correctly however the monitor doesn't work even after moving my mouse for a while and iam not sure if that's sleep or what exactly as i've set my PC to never go to sleep mode

the monitor doesn't get signal again unless i press the restart button on my PC

In the power profiles of windows, you have set the monitor condition to never sleep.
Then it should not happen.

If the monitor is the only device to do it. Then have a look around in the menu of the monitor its self to make sure its not the cause, it may be power saving when it detects no frequent display updated. in other words when the mouse pointer is static or no changes in refreshing the screen image.

The way to resolve the problem is to do with settings in the bios of the motherboard.
In the section related to power, you have options of power saving, and what windows does on entering sleep or suspend mode. If the right modes or S modes are not set right in the bios.
It can cause signaling of a device through the bios on wake up not to respond.
Advanced Configuration and Power Interface or ACPI menu of your bios.
When a request is made by windows OS, to wake up or send the computer into hibernation mode, or sleep or to turn off devices after a set passing of time it is routed to the Acpi of the motherboard bios.
