Question about Microsoft Windows Vista Ultimate Edition

Vista wakes up on it's own. Never goes to sleep.

I'm having 2 related but separate issues with the Vista Ultimate which came pre-installed on my HP Pavilion.

The first problem is that the machine wakes up on it's own after I have manually put it to sleep. This typically happens in the middle of the night but sometimes in the middle of the day. I've checked the "Power Troubleshooter" entries in the event log and they list the "Wake Source" as "Unknown" which isn't terribly helpful. I've already disabled my NIC, Mouse, and Keyboard from being able to wake the machine and gone through all of the devices in device manager and there are no other devices that I can find that are enabled to wake the computer. I've also gone through all of the scheduled tasks (including hidden ones) and none of them have permissions to wake the computer to run. I'm not sure what else to try. I did not have this problem when the computer was new so I suspect it may be related to something I have installed, but I would like to avoid uninstalling everything to troubleshoot that idea. What else can bring a computer out of sleep?

The second problem is that the machine never goes to sleep anymore, so when it wakes up it stays on wasting power. What I would like to find, if they exist, are tools which will help me troubleshoot what exactly is preventing the machine from going to sleep. Like the first problem, this did not happen when the computer was new. If I can solve this problem, I can live with the fact that the machine wakes up on it's own.

Another way to solve this would be to let it do the update at night, but then set it to go back to sleep. You can do it if you are comfy changing the registry values. Described here.

Re: Vista wakes up on it's own. Never goes to sleep.

Sounds like you've tried all the obvious things. Did you check the BIOS settings and turn off all of the WAKE ON settings in there? Otherwise, it sounds like you might have a third party program which is scheduling without your knowledge (check your start up programs and running processes during normal use). If, when asleep, the machine runs a fan, it may also be waking up for the OS to receive a power or overheat warning message from the BIOS.

Problems with machines not going to sleep when asked are often related to drivers that are not unloading when asked to prepare for the sleep/hibernation process. If you have installed any new hardware (or driver heavy software like specialized encryption or hard drive management stuff) trying uninstalling it and testing the sleep functionality.

Ideas, anyway.

Sleep/hibernate mode

Hi, If the computer seem to wake from sleep mode for no reason? Some device settings can cause the computer to return from a power savings state when not expected. If the computer is using an optical mouse, changes in light can cause the computer to wake. Network activity can cause the network hardware to wake the computer, especially when the network is always on (like cable and DSL connections). High Definition Audio audio may also cause the computer to wake from sleep mode. Use the following steps to prevent the these hardware devices from waking the computer:
  1. Click Start c00847244.gif , and then right-click Computer .
  2. Select Properties , and then click Device Manager in the left panel of the window.
  3. Click the plus sign ( + ) next to the device that needs to be adjusted. If you are using an optical mouse, select Mice and other pointing devices . If the computer is using an "always-on" connection, click Network Adapters . To check the high definition audio, click Sound, video, and game controllers .
  4. Double-click the name of the device to open a Properties window.
  5. Click the Power Management tab, and remove the selection from Allow this device to wake the computer . Figure 6: Power management tab for a mouse c00851648.gif NOTE: If you prevent the mouse from being able to wake the comuter, wake the computer using the Sleep button on the keyboard or from the power button on the front of the computer.
  6. Click OK , close the windows that are open, and then restart the computer.
  7. Click Start c00847244.gif , and select the Sleep/Standby button to see the problem still exists: If the problem still exists, go to the next Step.
  8. Disconnect all non-essential connected devices (printers, scanners, USB drives).
  9. Restart the computer with only the original mouse, monitor, and keyboard connected. If this resolves the sleep/standby problem, one of the connected devices was causing the problem. Replace one device and test to see if the problem occurs again. Continue adding devices and testing until the you find the device that is causing the problem.
If you have already tried all the above steps, you can try the steps below: Many software components start up automatically and run without being seen. Most of these programs are not necessary to the work performed on a computer, but can interfere with sleep/standby mode. For troubleshooting purposes use the following steps to prevent programs from starting when Windows is first opened.
  1. Click Start c00847244.gif , and then type msconfig into the Search field and then press the Enter key.
  2. The System Configuration Utility appears. Click the General tab, select Selective startup , and then and remove the check from Load startup items . c00847247.png
  3. Click OK to accept the changes and restart the computer.
  4. After completing these steps, Windows opens using Selective Startup. A small reminder may appear when Windows restarts. Select Don't show this dialog again and click OK to prevent the reminder from re-appearing every time the computer is restarted.
NOTE: To undo the changes made in this process repeat the steps above and replace the checkmark next to Load startup items .
  • If disabling Load startup items did not resolve the suspend problem, go to the next step.
  • If disabling Load startup items resolved the suspend problem, enable one startup item and test to see if the problem occurs again. Continue enabling startup items, until you find the software task that is causing the problem. Remove or update problem software.
If the problem still exists, go to the next Step. Upgrading the BIOS and keyboard software If the sleep button on the keyboard still does not work, go to the HP Software and Driver Download page , enter your computer model number into the field provided, and install any keyboard and BIOS updates for Windows Vista. Should you require any further assistance regarding this issue or any other computer related issue in future please feel free to contact get back to us, we will be more than glad to assist you.

Spacebar puts monitor to sleep

You can reboot your HP Pavilion, and while rebooting go to BIOS by constantly tapping F1. And then there has to be an option which you need to enable "Wake up by Space bar" option. Once you enable the option, save the BIOS settings and then try whether the issue persists or not.

Vista ultimate doesnot recover from sleep standby and hibernation with freezing of mouse

If you have a USB mouse, try these steps:

  1. Click Start, type device in the Start Search box, and then click Device Manager in the Programs list.
  2. In the User Account Control dialog box, click Continue.
  3. In Device Manager, expand Mice and other pointing devices.
  4. Right-click the USB mouse, and then click Properties.
  5. Click the Power Management tab.
  6. Click to clear the Allow this device to wake the computer check box, and
then click OK.

Vista have some problems with USB mouse and sleepmode and as far as I know there is no real "fix" for it so you just have to make sure it doesn't register the mouse while it's in sleep.

I hope this solves your problem. :)

No tv signal on wake up

I recently dealt with the same problem. Client had upgraded to Vista on a Gigabyte M-board equipped desktop, and sound was absent until reboot, whenever PC was aroused. Client wanted me to reinstall Vista. Installed with all peripherals connected and loaded all unrecognized drivers after install. Still same problem, and nmoticed many other features disappeared after wake-up as well (extra/dedicated keyboard functions, scroll wheel on mouse, PCI-based PCMCIA card and the modem!). Sound was all my client cared about, so I wrote mfg. and got this response: Our driver is OK, follows all Vista uniform specs and addresses S1/S3 properly, but Vista does not have all its wake up from suspend/hibernate resolved, for many of our components/drivers. This is a Vista problem that MS assures us is being addressed". Client was not happy with "waiting for MS to address the envelope, please" so we reinstalled XP 64b and all works fine now. This is also your choice: wait till MS-hell freezes over, -or go back to XP. (or install Linux). Sorry. Apparently, some Vista problems just can't be "addressed yet".
