One of the issues that some users reported is related to, believe it or not, Power Supply Unit malfunction. Namely, the PSU worked quite well before the upgrade occurred. However, after the upgrade to Windows 10, some power issues emerged. Of course, troubled users are sure that the upgrade had an impact on the matter at hand.

How to inspect power supply in Windows 10

1. Check hardware

First things first. Power Supply is the most common piece ofhardwarethat tends to malfunction. So, before you try some of the alternatives, make sure to check some of thehardware-wise features and confirm that everything works just like intended.

If something is wrong with the PSU, it’s safe to say that the replacement is needed. After you’re certain that everything is just like before, but the system upgrade caused issues, follow the instructions below.

2. Remove CMOS battery

Some users managed to resolve this problem by temporarily removing the CMOS battery from the motherboard. This battery main usage is to retain your BIOS settings, time, and date. This shouldn’t be affected by the system upgrade, but everything is possible in the PC world. We suggest a cautious approach, so if you’re inexperienced with the hardware meddling.

So, follow these instructions and look for changes:

Disable both and start your system, and your problems should be resolved.

All of this, of course, stands only if the PSU is perfectly functional. If not, you’ll need to replace it in order to restore the previous usability of your computer.

What they did is disabling Fast Boot and Hybrid Sleep. These two may be improvements in some regards, but not all of the motherboards are supported. So, if you’re not sure if your motherboard can or can’t support, especially if it’s older than 10 years or so, make sure to disable both features.

If you’re not certain how to do that, follow the instructions below:

That should do it. There are various ways to check what’s wrong with your PSU but they require advanced tools and knowledge. So, if the problem is persistent, make sure to replace your PSU or take it to a technician for a thorough check-up.
