Are you one of those people who keeps your PC running around the clock? If so, then you probably know the importance of sleep mode. Sleep mode allows your computer to save power and avoid overheating.

Does your PC shut down instead of going to sleep mode? This seems to be a common occurrence. However, most recently, users seem to have problems with their Realtek audio driver preventing their PCs from going to sleep mode.

What is preventing your PC from sleeping?

There are a number of reasons why your computer may not be sleeping. Below are some:

  • Power settings – Your PC’s power settings may be set to never sleep, hibernate or turn off. It’s also possible that the computer is simply not in a sleep state. To get the best power efficiency from Windows, you may need to tweak some settings.
  • Software conflicts – Some programs might be preventing Windows from sleeping properly. Examine any behavior and check whether it coincides with the recent installation of a new app.
  • Background apps – If you have a lot of applications open, or even just one that’s not responding, your computer may not be able to sleep until those apps have finished running. At times, a lot of non-essential services are running on your PC.
  • Antivirus programs – Antivirus software often monitors your system for malicious activity. Some virus scanners can prevent your PC from going to sleep by keeping certain processes running at all times. 
  • Driver issues – If you have recently updated drivers for any of your hardware components such as graphics card, these might be interrupting with Windows’s ability to sleep properly.
  • Power management tools – If you have installed third-party power management tools, your PC may not enter sleep mode. Third-party power management tools often have similar settings that prevent your PC from entering sleep mode. 
  • USB devices – USB audio devices such headphones or other devices such as printers and external hard drives can prevent a computer from going into sleep mode. 

What can I do to fix my Realtek audio driver from preventing sleep on my PC?

Perform the below basic checks before moving onto the more advanced steps:

  • Check your power settings and ensure Sleep mode is enabled. Sometimes the sleep option may be missing.
  • Disable all other sounds and notifications on your computer. You are likely to get a message that says an audio stream is currently in use when you force Sleep mode.
  • If you have any USB devices attached to your computer, disconnect them from the ports. If possible, turn off any hardware that’s connected directly to your computer or its power supply such as a printer.
  • Check if you have installed any new software or hardware recently and uninstall the programs.
  • Check with your antivirus software and temporarily disable it.
