I don't know much about these machines, but I wonder if its got some problem
with memory that gets corrupted when it reboots?

Is there any way on these machines to get into a bios or boot menu?

I'll see, when the battery has completely discharged, and I can start it
again!

Downloaded MS updates around 8-ish yesterday morning, and still waiting
for the battery to go completely flat.
