almost 1 month ago, my laptop battery having very low capacity / drop,
It can only use for 1 hour with normal usage (firefox, evolution, gnome-terminal, xmms)…:(
it only have design capacity: 1667 mAh before, and a week ago asking surabaya shop in THR
about how to fix and replace it if necessary…surely it can’t fix they said, they offer to
replace to battery cell with the new one (of course not original from HP) with only Rp. 600.000.

that’s still expensive for me, so I decided to search the internet about this problem,
some site having the information about how to maintenance the Lithium batt,
some of rule that I need to remember is:
1. do not plug the battery while you are using electric power more than 24 hours using
2. for the first time usage, charge the battery over 1 night with power off condition
3. having full charge and discharge minimum 4 times to get optimal battery performance

and for the user with drop battery that can’t be help with anyways, search the google how to minimize usage of unused hardware component like pcmcia, and optimize use of harddisk, cdrom, LCD that  can take most of the power of your battery.

so until then, now when the battery fully charged, I plug off the cable, so it using the battery power until fully discharged, and so on…
thanks God :D, the battery cell doesn’t damage, now my battery capacity is
[root@ichtusmobile ~]# cat /proc/acpi/battery/C11F/info

I think because before I never used the battery, it just need to "train" for fully charged and discharged cycles for refresh the battery
