You can experience different errors while using your Windows 10 computer, some related to the actual OS and some caused by some hardware malfunctions.
Well, if you recently received the System battery voltage is low error while trying to boot your device, we are mainly discussing a hardware issue.
Anyway, the guidelines below will tell you more about this particular error and provide yours with some troubleshooting methods that can help you repair your PC.
As you know, when you boot or reboot your device the BIOS is running in the background. That’s an interface that initiates start-up programs and the actual Windows system.
So, if the BIOS software isn’t working correctly, you will get boot problems along with other major malfunctions.
Therefore, the System battery voltage is low error is shown by this particular interface which signals a problem with a hardware component attached to the motherboard.
In most situations, the culprit is the BIOS battery which needs to be replaced. Yes, BIOS runs on a special battery attached to the motherboard which means that replacing it might require some hardware related tech experience.
Otherwise, we recommend you to take your device to service and ask for technical assistance. Anyhow, there are situations where the BIOS battery is not the actual problem.
So, before considering replacing this hardware component, try the following troubleshooting methods.
How do I fix System battery voltage is low error?
1. Reset/Update BIOS
If BIOS can be accessed, now it’s a good opportunity to reset it. This might also fix the System battery voltage is low error, in case the problem was reported accidentally due to a system malfunction.
So, go to BIOS and look for the Default Options entry. Access it and from there select Reset to default or Factory default. Confirm and save your options; then restart.
A BIOS update can be done in two ways: automatically, within BIOS if that’s an option included in your motherboard specifications or manually by downloading the BIOS update from your manufacturer’s official webpage.
2. Set up date and time in BIOS
Assuming that BIOS can be accessed, verify the system date and time. Set it correctly as the System battery voltage is low error might be caused by this mismatch.
If the time and date are not properly set, the system can perceive it as a security breach, thus you will be prevented from logging in to your Microsoft account.
3. Check the integrity of the motherboard
Before replacing the BIOS battery you should make sure that there’s nothing wrong with the actual motherboard components.
So, check the pins used to connect the other hardware devices, make sure that all the cables are properly connected and that hardware-wise all the parts are properly configured.
Of course, in order to do so you need to disassemble your computer, so be careful and try not to mess things up.
4. Check the regulators
If one, or more regulators are leaking the motherboard will not work correctly and everything might be interpreted as a voltage problem.
The regulators are there to memorize voltage data so a leak might cause the actual System battery voltage is low error that you see when you try to boot or reboot your computer, notebook or desktop.
5. Replace the BIOS battery
If any of the troubleshooting steps from above aren’t working, you should check the battery. So, disassemble your device and look for a small, round and shiny pill attached to the motherboard.
That’s the battery that must be changed. If possible, measure it as the battery normal voltage is 3.2-3.3V. If it is less than 2.8V the system will no longer function and that’s when you need to replace the BIOS battery.
The replacement procedure is rather simple, even if you’re not the handiest, tech-savvy person out there. Just turn off everything and unplug the power cord, for starters.
Then, open the casing and you locate the hand watch battery in the middle of the motherboard. Carefully pull the protective clip and remove the battery. Insert a new coin cell battery and make sure it’s firmly inside.
Even though all the troubleshooting solutions from above can be applied by anyone, we recommend you to take your Windows 10 device to service in order to avoid further problems – especially if you’re not really a tech guru.
However, usually, replacing the BIOS battery will remove the System battery voltage is low boot error.
