The “System battery voltage is low” error can usually be resolved easily enough but it certainly involves some advanced troubleshooting since everything needs to be done without the help of your operating system. This is yet another reason to follow the instructions carefully in order to keep your PC safe from triggering other problems. We have gathered several methods which have helped other people in the past so make sure you check them out below!
What Causes the “System battery voltage is low” Error on Windows?
There aren’t many unique causes of this error and they are pretty much related to BIOS or the CMOS battery. Still, two distinct causes can be identified and all the methods below are based upon them:
Solution 1: Reinsert or Replace Your CMOS Battery
One of the major causes of this problem is the CMOS battery. If the battery has been moved even slightly from its socket, the error might appear and prevent your PC from booting. If the battery is a couple of years old, it won’t be able to provide sufficient voltage to CMOS and this error is bound to occur. This is a clear sign that it’s time to replace the battery with a new one. These batteries are not expensive and you can’t boot your computer without them so make sure you follow the instructions below! Note: With some computers, you may need to disconnect cables, remove drives, or remove other parts of the computer to get physical access to the CMOS battery.
Solution 2: Clear the System Event Log
Another major cause of this problem is faulty BIOS settings. BIOS settings don’t get corrupt too often and it’s always a problem when they do. It may have been caused by an incorrect BIOS update or it can even be caused by a malicious program. Either way, if you can access BIOS, resetting it to default should definitely resolve the problem!
Solution 3: Update BIOS on Your Computer
Updating BIOS may be a difficult way of resolving the problem but users have reported that it has helped them. Note that the process differs from one manufacturer to another so make sure you take that into account. Follow the instructions below in order to install the latest version of BIOS on your computer and, hopefully, resolve the “System battery voltage is low” error!
