Black screen after maintenance wake

[gillmacca]

I am having an issue that only started at the weekend, and doing system restore hasn't solved it.
Running Windows 7 Ultimate, fully patched up with hibernation enabled.
If I wake my computer using my remote it works fine, but during the night my computer wakes up to do some maintenance/updating. Normally it would go back to sleep using MCE Standby tool.
Only changes made this week were some MS updates, and now it doesn't go back to sleep. When I turn the TV on all I get is a black screen, and I have to do a forced reboot.

Can anyone help?

Look through http://www.sevenforums.com/general-...-lags-every-couple-seconds-7.html#post1131640, and especially the parts referring to the event viewer logs and system file checks. Those logs should include information regarding the power/sleep cycles and any errors associated with those cycles. That would be the first place to check. Also, make sure all drivers are up to date, and re-install your graphics and network drivers even if they are up to date. It is possible you have corrupted drivers that are preventing the system from entering sleep again, and the network and display card adapter drivers are likely culprits with these types of problems.


To fully re-install a driver, use the following steps.

1. Click Start Menu
2. Right Click My Computer/Computer
3. Click Manage
4. Click Device Manager from the list on the left
5. Find the device you are trying to uninstall by expanding the appropriate set of devices
6. Right click the device
7. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
8. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
9. Restart your computer
10. Install the latest driver for the device once Windows starts.

Alternatively:

1. Login as an adminstrative user.
2. Click Start Menu
3. Click Control Panel
4. Click Hardware and Sound
5. Click Device Manager (the last link under Devices and Printers)
6. Find the device you are trying to uninstall by expanding the appropriate set of devices
7. Right click the device
8. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
9. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
10. Restart your computer
11. Install the latest driver for the device once Windows starts.
