Sorry if this has been asked/answered (The 'Click Here to Find..' button didn't pick any up, neither did a quick search)
I'm using a Dell Inspiron 6000, vanilla hardware setup, vanilla Ubuntu environment and kernel, standard ACPI and battery. The battery, however, wont charge, I know the battery is more or less sound (capacity is somewhat diminished, 90% or so of factory) because I have tested it in other boxes.
I have followed advice elsewhere such as 'unplug it whilst on AC' or 'let it run flat'. I have also checked the laptop it's self is having no problem by getting the batteyr stats in BIOS, which confims everythign I have said.
The output from
(to compare outputs) give me
jc@jcmain:~$ acpi -V
Battery 1: charged, 50%
Thermal 1: ok, 41.0 degrees C
AC Adapter 1: on-line
Battery #1 : charged, 50.61%, 1176:00:00
AC adapter : on-line
Thermal zone 1 : ok, 41 C
The alarm bells for me go off at 'charged' as opposed to 'charging'. The more vebose output:
jc@jcmain:~$ acpitool -B
Battery #1 : present
Remaining capacity : 1205 mAh, 50.61%, 1176:00:00
Design capacity : 4800 mAh
Last full capacity : 2381 mAh, 49.60% of design capacity
Capacity loss : 50.40%
Present rate : 1 mA
Charging state : charged
Battery type : rechargeable, LION
Model number : DELL UY4367
Serial number : 30072
Which is patently wrong. I have grepped dmesg for 'acpi', and compared the tail of the output before and after battery removal, since acpi is kernel based yadda yadda; nothing there of interest- certainly nothing outside of boot.
Can anybody suggest anything? Could maybe modprobing apm and looking at a different set of data help perhaps? Maybe my BIOS is wrong and charging on another box is merely putting it to this level and reporting as 100% because it sees it as 100% of available capacity?
(I'm sceptical over the latter, I have had this before and it has 'fixed its self' without charging elsewhere)
