Lenovo CMOS Battery

Greetings-
Got a Lenovo AIO Widows 11 desktop. How would one change the CMOS battery? Is it a rechargeable that never needs replacement?

It's usually a watch battery like a 2032. They need replacement now and then.

They are usually good for about 10 years or so. A windows 11 AIO should not need a new one already.

I know but curious. Looked this thing over and it appears there are no fasteners to remove to gain access to mother board. Totally seamless case except a small cutout cover on left side.

Remove the stand to make sure there's no screws underneath, and remove any of there are. Then starting at the bottom, slide a fingernail or plastic trim remover between the two halves and the case should start popping away from one another. The case is just two plastic halves like a clamshell.

Work around the edge until the rear of the case is free. Try not to pull and rip the rear off - the plastic clips may break off.

You might be able to find disassembly videos or pics if you Google how to disassemble your [insert specific computer model].

Cmos batteries are CR2032. Should be available just about anywhere.

Welcome to consumer grade crap. They make it pretty hard for the average Joe to get inside. It's probably mostly clips with some screws hidden here and there.

I would only change it if you currently have a cmos failure which you never stated if that is the case.

it was just a curiosity question for now. I have changed these things in the past

It's easy on a desktop but a bit more challenging with a laptop.

Lenovo's alleged "business grade" crap is just as bad.

You might want to try a google search on how to crack open the case. If you posted the exact model number some here may help also.

The old T-series Thinkpads, the design Lenovo inherited from IBM, were good, but they've steadily gone downhill on that front since then. The T-series were some of, if not the easiest to service machines out there.
