I recently updated my Inspiron 17R (7720) to the latest bios however as soon as it completed the process the battery stopped working. When I go into the bios there is the following message: "Your battery is temporarily disabled. Please turn off your computer and try again when the unit is back to the operational temperature". The machine has been left off for many hours now and is very cool to the touch however the battery wont engage and the issue persists between multiple battery packs (I have a backup battery too). As far as I can tell it is the bios that has broken my laptop and I am unable to fix it on my own. I have spent many hours trying to fix the issue at this point, following all of the advice that I can find on these forums. I suspect that either the bios has a bug or the laptop has a faulty sensor. Is anyone able to help?
