Adjust Power Settings

When a computer is in sleep mode, it saves power by turning off the display and reducing the power usage of components. I turned off sleep mode in the Control Panel and got back to normal functioning. This step was also working for the users on the Microsoft Forum. Take the steps mentioned below to resolve the issue.

  1. Access Power Settings: Open the Control Panel or Settings app > Power Options > Active Power Plan > Change Plan Settings.

Tip: Before proceeding to the complicated fixes, try the easy ones, such as updating the graphics card driver, properly connecting all cables, and removing any recently installed third-party software that may be hindering Windows’ functioning.

Change Sleep Mode Settings

Changing the sleep mode settings is a troubleshooting tip that can help solve issues when a computer doesn’t wake up from sleep mode in Windows 11. I modified the settings to ensure that my PC only goes to sleep after a particular period of inactivity. Users on 10 forums claimed that this step was of use to them. Also, taking this step solved the issue for us, you can take the following steps to do so:

  1. Access Sleep Menu: Go to Settings > System > Power & Sleep.
  2. Adjust Sleep Settings: Under the Sleep section, adjust the settings to your preferred sleep mode.

  3. Change Advanced Sleep Settings: Select Additional Power Settings from the Related Options. Here, you can customize the advanced power settings, including the sleep mode options such as hybrid sleep, hibernate, and sleep after.
  4. Save Changes And Exit:  Click Save Changes > Exit the Control Panel.

Tip: Corrupt or outdated BIOS can also hinder the PC’s functioning, causing errors such as the one at hand.

Disable Hibernation Mode

Hibernation mode is a power-saving setting that shuts down your computer after saving its present state to the hard drive. Disabling it can prevent the computer from getting stuck in this state and not waking up from sleep mode. This is how you can move ahead.

  1. Launch Command Prompt: Search Command Prompt in Windows Search Box > Run As Administrator.

Tip: One way to fix the issue is to do it using an SFC scan.

Check The Event Log

Checking the event log is an advanced troubleshooting technique that can help identify the cause of the issue. It lets you analyze the recent system events and if a problem is present in any of them. If found, resolve the problem to return uninterrupted PC performance. Taking this step was of great help to us at Tech4Gamers and other users online. Take the following steps to solve the issue:

  1. Open Event Viewer: Press the Windows+ X to open the Quick Link menu > Select Event Viewer.

WARNING: if all else fails and you decide to restore the system do so with caution and back up any important files beforehand.

I highly recommend using the basic fixes like running a System Diagnostics or disabling hibernation mode before moving into the more time-consuming ones.
