Sometimes, you may find your boot screen gets stuck with an error message “System Battery Voltage is Low” waiting for you to press the F1 key to continue.
This generally happens when the BIOS has difficulty fetching the hardware information from the CMOS. It can be caused by a depleted or faulty CMOS battery or a faulty sensor.
Whatever the causes, in this guide, we are going to provide workable fixes to get your system rid of this error.
How to Fix the “System Battery Voltage is Low” error?
A small battery powers the CMOS chip that stores the BIOS information for a system startup. This battery is not perpetual; its voltage can get low over time. This causes the system to beunable to connect with the CMOS chipand cannot load the boot information. As a result, it shows the error.
As the issue is related to the CMOS and BIOS, changing the battery or making some changes in the BIOS setting should solve the issue.
So, let’s not delay anymore and get into fixing the “System Battery Voltage is Low” error right away.
Sometimes, the BIOS information may get corrupted due to the installation of incompatible hardware, power failure, or Power-On-Self-Test (POST) errors. As a result, the BIOS may not be able to recognize the components or receive the boot information properly, causing the error.
So,resetting the BIOS settingsshould fix the problems in most cases. Let’s go through the way to reset BIOS settings to default.
See if the problem goes away.
Clear System Event Log in BIOS
The system event log (SEL) in BIOS consists of the power, temperature, failure, and diagnostics events during boot. Resetting BIOS does not clear SEL. So, if the memory allotted for storing the log files gets filled, or the SEL experiences some errors, then the issue of low system voltage may arise.
Clearing the system event log frees up the space and can fix the file solving the problem. But all the computersmay not have access to the system event login BIOS. So, if your system’s BIOS provides the function, let’s see the way to clear SEL.
Inspect whether the problem is still there.
Reinstall or Replace the CMOS Battery
