Description Andr 2004-03-04 12:27:24 UTC

present:                 yes
capacity state:          ok
charging state:          unknown
present rate:            unknown
remaining capacity:      4000 mAh
present voltage:         14800 mV

It would be nice to have the rate :\

Comment 1 Len Brown 2004-03-10 17:43:07 UTC

what rate -- seems like the battery is fully charged?

Comment 2 Andr 2004-03-11 10:47:32 UTC

present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            unknown
remaining capacity:      3440 mAh
present voltage:         14800 mV


86%


shouldn't there be a rate? I was under the impression that the "present rate"
should display the discharging rate, so that an ETA could be calculated.

what's the present rate for then?


Thanks

To me, it seems that an application should do what you said instead of kernel. 
Application should interpret it.

Comment 4 Andr 2004-03-15 02:34:54 UTC

what's that entry under /proc/acpi for then?

Comment 5 Len Brown 2004-11-15 20:25:06 UTC

works for me: 
 
[root@d600 BAT0]# cat state 
present:                 yes 
capacity state:          ok 
charging state:          discharging 
present rate:            23152 mW 
remaining capacity:      47950 mWh 
present voltage:         12542 mV 
 
can you re-test with linux-2.6.9?

present rate:            unknown
remaining capacity:      3800 mAh

Comment 7 Len Brown 2005-01-03 20:01:38 UTC

same with 2.6.10?
rate is always "unknown" no matter how long you've been running off battery?

Comment 8 Andr 2005-01-04 10:51:50 UTC

this one is from 2.6.10

present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            unknown
remaining capacity:      3840 mAh
present voltage:         14800 mV


and yes, it doesn't matter how much battery I have :(

It's really not a big deal, but it'd be good if this worked

Comment 9 Janez Dolinar 2005-02-01 23:30:28 UTC

I lost my "present rate" status after I flashed my BIOS with a "newer" version.
All attempts to get it back (I don't have the original BIOS) have failed.

Comment 10 Thomas Halva Labella 2005-07-27 23:39:36 UTC

present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            0 mA
remaining capacity:      2121 mAh
present voltage:         10978 mV

It would be too nice to have a rate of 0 mA! BTW: in the meanwhile my cpu is
working 100%...

Please reopen the bug if you still have the problem with latest acpi tree.
