Just a little addition to this topic:
As I have started commuting again I find myself using my laptop on the train to work and back, but battery time has decreased a whole lot since I got my system a year ago. I have had my nx9105 for exactly one year now and do not have an extra battery. The one I have is the 8 cell battery and the ACPI battery info tells a sad tale:
======================
[EMAIL PROTECTED]:~$ cat /proc/acpi/battery/BAT1/info
present: yes
design capacity: 4400 mAh
last full capacity: 1627g mAh
battery technology: rechargeable
design voltage: 14800 mV
design capacity warning: 220 mAh
design capacity low: 132 mAh
capacity granularity 1: 264 mAh
capacity granularity 2: 3780 mAh
model number: Primary
serial number:
battery type: Lion
OEM info: Hewlett-Packard
======================
Its current "full" capacity is almost down to one third of the design rating! The only batteries that have gone useless faster than this on me are the Thinkpad 600E batteries which are known to be broken by design.
Anyone else care to show their battery info, and if you have managed to keep it at an OK rating - how did you do it? I'm not entirely ignorant about lithium ion batteries and how they should be treated.

Norm: Thanks. Ill check out the site.
I guess I'll just get a 12 cell battery; heard they last for a very long
time (and from Jonathan's previous mail).
