What could be causing your CMOS battery to fail after just one month?
What could be causing your CMOS battery to fail after just one month?
They could just be low-quality batteries or already expired.
Did you purchase a bundle of 20 CR2032 cells for $2?
I steer clear of overpriced, single-cell packs found at supermarket checkout counters.
Instead, I opt for trusted quality brands in larger quantities from reliable suppliers. Their shelf life is typically five years or more, and I anticipate using them for at least two to three years after installation in a mobile device.
@Misgar shares useful tips... unrelated, when you don't use your computer do you turn it off and/or disconnect it from the power source?
If I left all my computers in standby mode, I'd probably waste over 100W of vampire power. Then there's the 20 to 30W drawn by the 1500VA APC UPS when idle. Add to that the broadband fibre modem, a pfSense firewall, a Netgear firewall, 8-port Gigabit switch, 8-port 10GbE switch, WiFi AP, audio DAC, etc.
With power costing roughly $0.60 per kWHr, I normally switch off my computers at the wall when not in use. I also kill most of the network at night if I'm not downloading anything.
I've got enough freezers, central heating system, cooker, microwave, dish washer, washing machine, lights, hifi, TVs, to use thousands of dollars worth of power, now that prices have rocketed due to the invasion of Ukraine.
I've switched off some computers hundreds, possibly thousands of times during their life. So far very few PSUs have given up the ghost.
No issue, just trying to figure out the issue... the CMOS battery is mainly used when the computer isn't connected to power, which supplies backup for time and BIOS settings. If it's off more than on, it suggests the battery is being used more often than if the machine was always plugged in. However, it might indicate a short or faulty component—perhaps a device that draws power even when the computer is off.
Understood. I wouldn't anticipate the CMOS real time clock and BIOS backup consuming more than a milliAmp or two. My CR2032 batteries typically last up to five years in most devices.
