Most do this at boot so if Robert did a full power reset he should be
fine. There is no need to run a utility or manually run the battery down.
Older, Ni-Cad, laptops did have calibration utilities in their BIOS.
No longer the case with Li-On.
I received a new battery from IBM. They shipped it from the Harrisburg,
PA warehouse to me here in Waikoloa HI (IEEE 802 plenary meeting) in 2
days. They included a shipping label to send back the old battery, so
that is on its way.
After 4 hours on AC and running, the F16 battery icon is reporting 100%
charged but showing the charging icon. When it first showed 100%, I
unplugged and was 'told' I ahd 3 hours battery. That was after about
1.5 hours charging (it came 30% charged). WHen I unplugged a few
minutes ago, I got 'estimating' for a couple minutes and then it came
back with 8 hours. I plugged back in and it is again showing 100%
charge and charging.
No instructions or tools were included. When I get home friday, I will
check the battery instructions I got with the unit and figure out what I
might do. I really don't know how say a DOS utility would work to run
down the battery; how do I boot DOS? From USB? (I do have a USB
diskette drive!)
I am also going to order a second battery tonight. I have EU next week,
so I want a little more insurance.
