I own a low-cost, off-brand mini PC that stopped working when just six months old. That was too bad, as I liked the machine. The supposed one-year warranty from the no-name manufacturer was a joke. They didn't respond to my attempts to contact them and seem to have gone out of business. The pattern of malfunctioning I observed for this PC up until the time it completely died matched the symptoms of a failing BIOS battery. In particular, there were months of erratic booting and, toward the end, the system clock slowed down and behaved erratically. But the machine was just six months old, so I found the "bad BIOS battery" diagnosis impossible to believe. (BIOS batteries should last years and years.) Although skeptical, I removed the BIOS battery from the PC and measured its voltage. It was fine: exactly 3 volts. That seemed to rule out the BIOS battery as a source of the malfunction. But with nothing else to try, I ordered this LeFix replacement BIOS battery anyway to see if that would make a difference. When the new battery arrived last month, I plopped it into my PC, screwed the PC's case back together, and plugged in the machine. I thoroughly expected the machine to remain dead as before, but—amazingly—the PC sprang to life immediately and has worked fine ever since! Go figure.

My Elitebook suddenly got a CMOS error, causing the whole laptop to stop booting. I buyed the product and it came 2 days before the estimated delivery time! The laptop is working again and this is the only advertisement that didn’t cost me too much money ;). Great seller 👍 you’ve saved my laptop.
