1 Hi,
2 i'm running Gentoo latest version on a Sony Vaio laptop (fs115s)
3 and i'm in a big trouble with battery life management.
4 I'm using these versions:
5
6 acpi-0.06-r5
7 acpid-1.0.4-r2
8
9 and this is what /proc/acpi/battery/BAT0/info
10 show to me:
11
12 present: yes
13 design capacity: 10000 mWh
14 last full capacity: 10000 mWh
15 battery technology: non-rechargeable
16 design voltage: unknown
17 design capacity warning: 1000 mWh
18 design capacity low: 400 mWh
19 capacity granularity 1: 100 mWh
20 capacity granularity 2: 100 mWh
21 model number:
22 serial number:
23 battery type: LiOn
24 OEM info: Sony Corp.
25
26 and /proc/acpi/battery/BAT0/ state:
27
28 present: yes
29 capacity state: ok
30 charging state: charging
31 present rate: unknown
32 remaining capacity: 1900 mWh
33 present voltage: unknown
34
35 As you can see from these files design capacity is recognized as 10000 mWh
36 when reading from battery specifications:
37
38 11.1 V
39 4400 mA
40
41 should give 48840 mWh.
42 Furthermore present and design voltage are recognized as "unknown" and
43 battery technology as "non-rechargeable" !
44 This puzzling situation leads to a battery life of about 1 hour and a half.
45
46 Please if someone has ANY ideas on how to bring things in the right way,
47 PLEASE HELP ME !!

49 Many thanks,
50 cheers,
51 Max.
