monitors no wakey from sleep mode

sometimes not all the time after my pc has been in sleep mode
the monitors dont come back on, i can see the pc wakes up but the monitors stay black and so far the only way ive got it to work is to power off and reboot.
all my drivers are upto date what could be causing this i dont realy want to disable the sleep mode?
thanks

just a thought, i assume they are both USB keyboard and mouse. check your power settings and make sure the usb isnt allowed to go into a reduced power state after so long.

I occasionally have the same problems. I have tried everything I can think of during the event, to no avail. The best theory I can dome up with is a driver issue.

True, but it could still apply.

Hi Maxheadroom, i had this problem & it took about a month before i found the solution in the end it was a Ram related issue for me i underline this because in my research i found there is so many different reasons it could be happening from one machine to the next this link to a vista tutorial is a good place to start Power Options and Sleep Mode Problems - Vista Forums even though its a vista tut. it is the same principals for 7. If you dont find a solution within the tutorial i would reccommend reading the posts submitted at the end as you will find a lot of differnent things that have worked for others

Same problem here. It started when I went to 4gb memory. I'm running Windows 7(64)bit. I installed Windows with 2gb, then upgraded to 4. Everything else is running as it should, but when the computer goes into sleep mode the monitor wont turn back on. For now I've disabled sleep. Someone posted that it was a ram problem for him too, so I'll check the vista thread he suggested.

thanks ill have a look at those links.
when you say it was a RAM issue was there a problem with the actual RAM itself as in a fault?
my RAM is new and ive still yet to test it.

You guys might want to compare your monitors, like how old or what type of connections.

Recycling the monitor means turning it on an off.

This utility, which I don't really notice comments about monitors, but something else may show up is meant to diagnose you sleep capability. Don't have any other programs running and make not of where it stores the resulting report.

Start a Admin prompt. Winkey -type cmd - CTRL-Shift + Enter the allow and type this (without quotes and a space after g) in the command window.

"powercfg -energy"

It will save a report to the Windows\System32 folder called energy-report.html. Maybe you will notice something. There is always a possibility you might need to update your Bios, or a driver for the monitor.
