Not a new question particularly - got a replacement battery from here only for the BIOS to tell me it's unrecognised (not OEM) and won't be charged. Tried [link|https://forums.tomsguide.com/threads/dell-xps-12-replacement-battery-not-recognized.144719/#post-605394|this|new_window=true] to no avail. Also flashed with the latest BIOS from Dell...
Removed the CMOS battery temporarily, can't get it to charge - LED remains flashing alternately white/amber.
I'm running ubuntu, not windows... any ideas gratefully received.
