That message is printed on startup if bits 6-7 in CMOS RAM byte &1C (the
famed DragASprite byte) are set to 1. 0 means last shutdown was OK, 1 means
due to battery failure, 2 means due to battery failure and the auto shutdown
procedure failed to complete, and 3 is undefined. However having printed the
message, the Switcher then clears those bits back to 0. They should only get
set by !BatMgr if your battery dies on you. So the intriguing thing here is
why you keep getting this message. Is something in your boot sequence
messing with your CMOS RAM?

Try manually setting those bits to 0 or even to 2 (you get a different
message with 2), do a hard reset and see what happens. Setting the bits to 3
is also worth a try - the window should display a message telling you the
shutdown state is invalid.
