Random hangs after monitor comes out of power save mode

[GChar7]

I have a Lenovo ThinkServer TS130-1105 running Win 7 64bit Pro connected to two Dell U2212HM 1920x1080 screens. One is usually off. Power saving is set to turn off the monitors after 5 mins. For months it has worked fine and then all of a sudden about 2-3 months ago after the monitors are put into powersave, if I move the mouse to wake them up, the system is frozen. The mouse sometimes moves around for a few seconds and then it freezes too (usually it freezes the moment the monitors wake up). Then (usually) after 10-40 seconds the system unfreezes. Based on my screen clock, it looks like the system is frozen around the time the monitors go into power save, as that's the time frozen on the screen (even the second hand) until the unfreeze, at which time the clock is restored to correct time).

I have loaded the latest drivers I could find for the Intel HD Graphics and Dell monitors (actually didn't used to have a Dell driver before and it was working fine, but adding the Dell driver made no difference).

The only think I've noticed that sometimes helps a little is to unplug the monitors' power supplies for 20-30 seconds and then plug them back in. This usually gives 2-3 days relief, but once the problem starts it can occur randomly, sometimes almost every time the monitors go into powersave. I've tried unplugging all USB devices from the monitors and even the monitors' USB connections to the desktop, thinking perhaps the USB was causing the problem, but it made no difference.

Below is the report put out by the Intel HD Graphics utility.

Any help or suggestions would be much appreciated.

Thanks

Try updating the BIOS for the system you have. For this follow this link:

http://support.lenovo.com/es_VE/downloads/detail.page?DocID=HT051085 Drivers and software - ThinkServer TS130 (1098, 1100, 1105, 1106)

Also try loading the driver for the monitors you have connected.

In addition you can try using an older generic driver for the Intel® HD Graphics 3000. This is available here:

Download Center

In addition check for any operating system settings that could have been changed and that may be related to this kind of behavior.

Furthermore, please keep in mind that the drivers we provide in our web site are for Intel® HD Graphics series, in your case, the P3000 drivers should be provided by Lenovo directly. so check with them for an updated driver for this system if the issue persists.
