For some reason my XPS 12 2 in 1 running windows 10 now says that it is plugged in but not charging. When I start up the computer I get stoped at boot with "The battery charging is temporarily disabled. Press f2 entering BISO setup menu. Battery status for details.
You go into the BIOS and go to Advanced and under battery it says "This battery is temporarily disabled. reseat the AC adapter and try again when the unit is back to operational temperature.
