One of the most common problems with laptops is replacing the CMOS battery when it dies, because usually is located on a difficult access place & its necessary to disarm almost the entire laptop motherboard to get it.
So I wonder what is the location of the CMOS battery on the Framework Laptop motherboard, if its also easy to replace & which battery model does it uses (because most PCs uses the classic CR2032 but some models uses a different model)?
You can see it in this picture:
I can’t make out the size, but it seems to be very easily accessible and no soldering is required for exchanging it.
@Guillermo_Gomez the CMOS battery is on the mainboard as @iFreilicht noted.
We do not use a CR2032, but instead use a rechargeable battery, which hopefully means you will almost never need to replace it.
To replace the battery you only need to loosen the 5 screws for the keyboard cover, lift up and then you have access to replace it.
@Kieran_Levin that’s awesome, I didn’t even know rechargeable button cells existed. Really makes you wonder why everyone doesn’t do it that way, it just seems like the right way to go. I love the amount of details you’ve been thinking about, just makes me more excited to get one of these on my hands!
When I saw the board on Tested. I noticed that the CMOS battery is on the board unlike most laptop that has the battery routed on external compartment thus save the trouble from the battery leakage in the future. Hope your engineering team thought of that in next board revision. Lots of other laptop manufacturers such Lenovo put in external compartment. Thanks
Many laptops put the battery off-board to reduce board area usage. For us, the optimization was slightly different. We put the battery on-board to reduce the number of connectors required for a mainboard replacement and to make it easier to re-use the mainboard outside of a Framework Laptop.
Just a connector and create battery compartment like Thinkpad T440 and route the battery. That’s cost few cent for connector probably cheaper than current connector in use. No screw just clip the JST style connector. I have Odroid H2+. The CMOS share the same JST connector. It doesn’t make it harder to use outside of the the case. In this example the laptop. Making the laptop reliable and linux compatible what make Thinkpad lovable. I hope framework to be successful in order to reduce e-waste
