hello all,
What's a good way to zero a laptop battery? Long ago, when batteries were
still Ni-Cd i destroyed a hard drive by just keeping the computer on battery
power until it would go off by itself because there was just no more power.
I haven't had to do that lately because it's not supposed to be necessary
to zero Lithium Ion batteries. Or, it's a good idea to do it sometimes but
not really necessary since Lithium ion doesn't have a memory effect.
But i think i'd like to zero my battery maybe once a month. What would
be a good way to do this?
I'm thinking, maybe, use the computer on battery until i'm down to 10%
or so, or maybe even 5%. then apm -s. because of keeping memory
alive, power is still used. at some point power will be completely gone
and apm won't wake up and instead the computer will reboot.
are there better options? maybe set the CMOS to have the hard drive
spin down after ten minutes of inactivity and then boot from a CD and
just never mount the hard drive? so it would spin down because it's
just never accessed?
are there better informed opinions on whether LI+ batteries need to be
zeroed at all. and how often they should be zeroed?
