[Chillmiser]

Hi to all,

I have a Windows 7 and my issue is related to sleep mode. Whenever i makes my system in sleep mode my monitor never turns on back. I have to every time power off machine and have to restart it manually. What could be the reason for this fault? is it monitor issue or windows 7 settings are having some fault? please resolve my issue. many many thanks.....

From when its happening? any changes made recently in system? which monitor you are using with windows 7? does this monitor works fine with another operating systems? do you have dual boot? if so then is same thing happens with the another OS also ? by this way you can figure out if the problem is with windows 7 or your monitor.

Boot into safe mode by pressing F8 when you system bots up and select safe mode. After booting in safe mode go into control panel and turn off all power management by setting them to never in the power option settings. And also turn off the hibernate option.

The first thing to verify is that all your drivers are properly installed. Upgrade the video drivers first, Go into Device manager and check if you find any yellow exclamation marks in front of any hardware device entry. If you find the install drivers for that hardware.

Perform the following steps:

1) Click on Programs -> Settings -> Control panel
2) Now go to Power Options
3) In Power Schemes select Turn Off Monitor,HDD and system standby and Hibernate by seleting the "Never option" And click on Apply.
4) Repeat the all above 3 steps for every power scheme.
