I recently formatted my pc and installed Vista on the main partition and Windows 7 on another smaller partition. Ever since, whenever I'm in Vista it goes to sleep and I try to wake it up, it seems to wake up and there is CPU activity but the screen remains blank and then I have to do a hard shutdown.
please help me thank you.
If you have an NVIDIA card, I've had the same problem. The 18x Series GeForce Driver Releases seem to give some set-ups this problem.
It can usually be fixed by latest driver installation .
A wireless mouse and keyboard can cause your computer to wake up for no apparent reason, and to not wake up from sleep mode when you press a key or move the mouse. This may also cause your screen saver to not work to. If the computer is using an optical mouse, changes in light can cause the computer to wake.
For a USB Mouse or Keyboard:
1. Check the BIOS settings to make sure that you have a Legacy USB option enabled.
For a Wireless Mouse or Keyboard:
1. Unplug the receiver on the back of the computer and test.
2. If sleep or hibernation works now, then try:
A) Download new drivers for you wireless mouse and test again with the receiver plugged in.
NOTE: Always get your drivers from the source, never from Windows Updates. They do not work properly sometimes.
B) Disable the wireless mouse and/or keyboard wake up option in Step Five below. If you have to disable both of them, then you can wake the computer up by pressing the power button on the case.
C) Time to get a new mouse and/or keyboard that is compatible with Vista.
For a Optical Mouse:
1. Try not to have direct bright light shining on the sensor or moving around it.
ower settings control the computer’s ability to go into and come out of sleep/standby mode.
1. Open the Control Panel. (Classic View)
2. Click on the Power Options icon.
3. Click on the Change plan settings link under your power plan
Make sure you have the latest Video drivers and BIOS for your motherboard. Read your motherboard manual to see if you have any jumpers or settings that sets different sleep voltages for USB.
1. Open the Start Menu.
2. In white line (Start Search) area, type cmd and press Enter.
3. In command prompt, type powercfg -a and press Enter.
4.Restart the computer into the BIOS settings, and go into the Power Management section in the BIOS.
5. Make sure ACPI mode: S3 or S1 is enabled.
