BIOS date and time always resets on Dell Latitude e5420 after replacing battery.
Hello all, I recently replaced the battery on my laptop (Dell Latitude e5420), but found that on every cold boot, the date and time resets to sometime in September 2015, requiring a reset always. This does not happen on reboots though. Is there a solution to this problem?
Huge fan of Windows Vista, 7, 8.x, XP, 2K, ME and Linux, especially Zorin Linux, Ubuntu, elementaryOS and Mint.
I hate Windows 10. I am the last person one could ever convince to downgrade to Windows 10.

I think the laptop has a CMOS battery, and for some reason the CMOS isn't powered by the laptop battery. I don't know tbh.

I agree with K4sum1, Every computer has a "coin" battery to keep system configuration settings saved, date and time included. Typically a 2032 battery as in my case. Most laptops I've owned have an easily accessible panel on the bottom, likely retained by a small screw, to access it. I'm not familiar with that exact model, but it should be pretty straightforward replacing it.
