Windows 7 New HTPC Windows 7 will not sleep when it should

[Forum2Jack]

I have changed my HTPC from a tower to the HTPC case. New everything except the Ceton InfiniTV 4 PCI card/cable card.
Have identical Windows 7/64 Pro systems. Tried to copy all the power / sleep settings.

New HTPC system will not sleep when it should. It is set to sleep after 10 minutes.

The machine wakes up between 3-4AM and 3-4 PM every day.

After 10 minutes of idle after Windows Media Center stops recording it goes into Sleep but wakes up seconds later.

Tried various combinations of settings. How can I get sleep to work correctly????

Hardware
MB Gigabyte GA-78LMT-USB3, AMD Fx6300, Wireless USB Netgear N900

The last time it woke up the system event log said it was the pci bridge

Wake Source: Device -PCI standard PCI-to-PCI bridge

It never goes to sleep on the timer of 10 minutes which it is set to.

Any ideas??

To troubleshoot the sleep issues on your new HTPC system running Windows 7/64 Pro, especially in relation to the wake-up events happening at specific times and the failure to sleep after the defined period, we can try a few methods to diagnose and potentially resolve the problem:

1. Check Power Settings​

• Power Plan Settings: Ensure that the power plan is set correctly and that all devices are allowed to put the computer to sleep.
• Advanced Power Settings: Check the advanced power settings to ensure that nothing is preventing the computer from entering sleep mode.

2. Identify Wake Timers​

• Command Prompt: Use the command powercfg -lastwake in the Command Prompt to identify the device or task that woke up the system.
• Task Scheduler: Check the Task Scheduler for any tasks that might be waking up the system.

3. Update Drivers​

• PCI Bridge Driver: Update the driver for the PCI standard PCI-to-PCI bridge. Device Manager can help locate the driver and check for updates.

  4. Disable Wake on LAN​

• BIOS Settings: Check if Wake on LAN is enabled in the BIOS and disable it if it's causing unwanted wake-ups.

  5. Network Adapter Settings​

• Device Manager: In Device Manager, go to the properties of your network adapter (Netgear N900 in your case), and ensure that it is not allowed to wake the computer.

  6. Windows Media Center​

• Recording and Playback: Check the settings in Windows Media Center regarding recording schedules and background tasks that might be preventing sleep.

  7. Windows Update​

• Ensure all Windows Updates are installed. Sometimes updates include fixes for power management issues.

  8. Event Viewer​

• Event Viewer: Monitor Event Viewer for any critical errors or warnings related to sleep or wake events. The specifics in the logs might provide more insights into the issue.

  Action Steps:​

  1. Check the Power Settings and Advanced Power Settings to ensure sleep is allowed.
  2. Use powercfg -lastwake to identify the device waking up the system.
  3. Update the driver for the PCI bridge if needed.
  4. Disable Wake on LAN in BIOS settings.
  5. Check network adapter settings.
  6. Review Windows Media Center settings.
  7. Ensure Windows is up to date with all updates installed. By following these steps, you should be able to pinpoint the issue causing the HTPC not to sleep properly and resolve it effectively.
