Standalone Operation (Laptop Only)

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• No

Describe the bug

-The battery refuses to charge beyond current charge level, but will maintain it.
-Turning off the pc will top it off to 100%.
-Lowering the Max Charge Limit to a lower percentage through eg Framework control will drain the battery to the lower percentage. Resetting the charge limit to 100% will stop draining the battery, but it will not charge beyond the current percentage.
-OS and Framework Control battery status indicators show a constant switching between charging and discharging (presumably to keep state within the current percentage).

Steps To Reproduce

1: disconnect from AC
2: drain battery below 100%
3: plug in AC
4: observe charge percentage holding.

Expected behavior

Battery should charge to 100% when plugged in with current settings.

Additional context

Battery charge limit is set to 100% in BIOS
I've tried battery disconnect and waiting ~10mins to reset EC with no success (but I do have an RTC battery installed so unsure if that has the intended effect).

board and battery have worked flawlessly and have charged for the as expected since ordered September '25 until last week. board and battery have not been separated since installation.
