Computer won't wake up from deep sleep

[JoeNB]

Recently purchased an All-in-One pc and when it is in the sleep mode for a long period of time, the only way I can wake it up is to turn it off and back on. There must be another way to wake it up.

Hi @JoeNB,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your All-in-One PC won't wake up from deep sleep, here are some steps you can try to resolve the issue:

1. Check Power Settings

Adjust Sleep Settings:

• Go to Settings > System > Power & sleep.
• Under Sleep, adjust the time settings to prevent it from going into deep sleep.

Change Advanced Power Settings:

• In the same menu, click on Additional power settings.
• Select your power plan and click Change plan settings > Change advanced power settings.
• Expand Sleep and make sure Sleep after and Allow hybrid sleep are set to your preference.

2. Update Drivers

Update Graphics Drivers:

• Go to Device Manager (right-click the Start button).
• Expand Display adapters, right-click your graphics driver, and select Update driver.

Update All Drivers:

• Consider checking for updates for other drivers, especially those related to power management and chipset.

3. Disable Fast Startup

1. Turn Off Fast Startup:
   • Go to Control Panel > Power Options > Choose what the power buttons do.
   • Click on Change settings that are currently unavailable.
   • Uncheck Turn on fast startup and save the changes.

4. Check Wake Timers

1. Enable Wake Timers:
   • In the Power Options, under your selected plan, go to Change advanced power settings.
   • Expand Sleep, then Allow wake timers, and set it to Enable.

5. Check Device Settings

Allow Devices to Wake the Computer:

• Go to Device Manager.
• Expand Network adapters, right-click your network adapter, select Properties, and go to the Power Management tab.
• Check Allow this device to wake the computer.

Check Other Devices:

• Do the same for any other devices that may support wake functionality (e.g., USB devices).

6. BIOS/UEFI Settings

1. Check Wake Settings:
   • Enter the BIOS/UEFI settings during boot (usually by pressing F2, F10, or Delete).
   • Look for any power management settings that might affect sleep and wake functionality and ensure they are enabled.

7. Perform System Updates

1. Check for Windows Updates:
   • Go to Settings > Update & Security > Windows Update and install any available updates.

I hope this helps.

Take care and have a good day.
