20 Best Ways to Fix a Computer That Won’t Wake from Sleep

It’s not always best to shut down your Windows PC, especially if you want to boost your productivity by keeping documents and files running in the background so you can pick up right where you left off.

Sleep mode is an efficient power option for your device because it allows you to pick up where you left off if you don’t leave your computer for an extended period of time.

Any open windows and their original state are stored in your PC’s RAM, and if your battery runs out while in sleep mode, your computer will immediately save your memory state to your hard drive and restart when you reconnect.

To instantly return the computer to a working state, it is usually enough to press a key on the keyboard or move the mouse. However, there are times when your computer freezes and cannot resume sleep despite constantly pressing keyboard or mouse buttons.

If you do not use your device for an extended period of time, your computer will not wake up from sleep until you hold down the power button and restart it.

If you are facing similar issues on your system, read on to find out the possible causes and top 20 ways to fix the “Computer won’t wake up” error.

The problem may occur if one or more of the following criteria is true:

  1. The device drivers and chipset are either not up to date or are corrupted.

  6. The hiberfil.sys file is outdated and corrupted
  7. Corrupted system files and/or applications.

While these are the most common causes that can lead to the problem, there are a few other factors that you may need to pay attention to. Let’s now proceed to all the possible solutions to the problem:

Fix Computer Won’t Wake From Sleep or Hibernate in Windows

Restart your computer

First, your computer needs to restart so that you can review possible issues. If your PC is stuck on a blank screen or frozen, you will need to force restart to turn it back on.

Option 1: To force restart your computer, hold down the power button for a few seconds, wait at least 30 seconds in between, and then turn the power back on normally.

Option 2: If your computer screen is on but it is frozen or frozen, press Ctrl+Alt+Delete → select the Restart option from the drop-down menu after clicking on the power icon in the bottom right corner.

Remap sleep key

If your USB keyboard doesn’t wake your computer from sleep and you don’t have a dedicated sleep keyboard button, follow these steps to assign a key:

  1. If your computer is running Windows 7 or Windows Vista operating system, go to Start → type “keyboard” in the search area → select Keyboard or Microsoft Keyboard from the search results.

(For Windows XP, select Run → type “control keyboard”→ click OK.)

  1. To use the Key Remapping Wizard, double-click on the key you want to change in the Key Options tab.
  2. Click “Next”after selecting the “Run a program”, “Web page”, or “File”option.
  3. To get the key to start hibernation, run the following command:

rundll32.exe powrprof.dll
SetSuspendState

(Be sure to leave a space before and after powrprof.dll)

For Windows 10 and later, there is no direct way in Settings to remap the keys, so you will have to download third party or additional software like Microsoft PowerToys or SharpKeys to map the key.

In PowerToys, you can assign the key you want to change in the “Key:”section of the “Remap Keys”tab, and then select the desired key in the “Mapped To:”section (you can also select multiple key combinations), then click OK “.
