Symptoms of a Failing CMOS Battery
So, how do you know if your CMOS battery is on its last leg? Here are some common symptoms to look out for:
1. Incorrect System Time: Ever noticed your computer clock is always off? If your system time keeps resetting, that’s a huge red flag.
2. BIOS Settings Reset: If you find yourself constantly re-entering your BIOS settings, it’s likely because the battery isn’t holding a charge anymore.
3. Error Messages at Startup: You might see messages about “CMOS Checksum Error” or similar warnings. Don’t panic; it just points to a battery issue.
These symptoms can be a nuisance, not to mention they affect your overall computer experience. So, if you spot any of these, let’s get to fixing it!

7. Power On the Computer and Re-enter BIOS Settings: Once you turn it back on, you might need to adjust your time and settings in the BIOS again.
By following these steps, you’ll breathe new life into your computer!
General Steps for Removing and Replacing CMOS Batteries
If you’re a bit more tech-savvy or have a different brand, fear not! The basic steps for removing and replacing CMOS batteries are pretty universal. Here’s a quick rundown:
1. Power Down and Disconnect Cables: Always do this first. It’s essential for your safety.
2. Open the Computer Case: As mentioned before, unscrew or unclip the case to get inside.
3. Identify and Remove the Old Battery: This is pretty straightforward—find the battery and pop it out.
4. Insert the New Battery: Just like with Dell, make sure the orientation is correct.
