I found (from experience) that is mobo will not power up due to a BIOS fault. When the battery is low
there is a defect in the code that also does not allow it to charge the battery! Of coure if you send to Dell
they tell you they replace the mobo at liek $500 cost what a joke. You only need to borrow a battery that is
charged and plug into the power brick. Then have a foppy ready to flash to A11 upate level - then all worries
are gone! Works great after that... Just wanted to share my tip. Maybe save someone a few $$$.
