Like many of you, I snagged a mystery box mainboard and I’m having a slight issue. Luckily mine boots and works since I had a Framework chassis laying around. The issue is that the CMOS battery holder is simply not there. Does anyone know if it’s possible to source a replacement? It looks like the plus and minus terminals are still there so that’s a plus. Technically speaking I dont HAVE to have the CMOS, but I’d like to get the part if I can find one.
It seems like maybe the 12th gen doesnt use a CMOS battery anyway? How do you maintain BIOS settings without a battery if I wanted to print a case?
If you intend to run it outside of a laptop, you will indeed need an RTC battery.

There’s this one from https://frame.work/products/16-rtc-battery-cable but any 3V rechargeable lithium battery should do.
Can you test something for me? I have a couple 12th gen boards as well, but no 13 laptop chassis to test in. Mine do not show any video output.
Will your board still boot or show video outside the chassis with video connected through usb? This will help me, and others, to determine if we need to first boot with an “internal” screen attached to be able to change it to output over usb (and of course need a cmos battery attached).
I could NOT get it to actually boot until I threw it in the chassis and hooked up the swollen battery and framework screen I had. I would get the Framework splash screen occasionally with USB video out but it would fail there.

I just tried it again with the display and battery disconnected. It successfully booted and ran. It of course discarded my BIOS settings however. I had ran firmware updates in Bluefin prior to this test. It could be a firmware change?
I looked at that RTC battery previously, but I dont see an obvious plug for it on my mainboard. In the pictures, it appears to be used for a 16” mainboard.
I don’t have a FW13, but from your photo, it should be possible to solder the wires to the contacts there (middle of photo):
That battery is for the amd motherboards I think. Not sure why Framework is not selling the correct ones for any other boards. But you can probably just cut off that connector and solder the wires to the board where the battery holder would normally go.
Im an idiot. I went to their GitHub page but didnt scroll down. They literally list the part number they use for exactly the OEM part. While yes, I agree that I could probably get away with cutting and soldering that battery they sell, I’d rather just slap the correct part in place. I appreciate the community involvement though.
