Dotaz: ThinkPad R500 - vydrz baterie

[pele]

Zdravim, jste nekdo z Vas vlastnikem ThinkPad R500 (2732-32G)?

Muzete se se mnou podelit o informace o vydrzi na baterie?

Moje bateriem jak ji vidi acpi:

Battery 0: design capacity 4178 mAh, last full capacity 4178 mAh = 100%

Podle proc:

cat /proc/acpi/battery/BAT0/info 
present:                 yes
design capacity:         51840 mWh
last full capacity:      51840 mWh
battery technology:      rechargeable
design voltage:          10800 mV
design capacity warning: 2592 mWh
design capacity low:     200 mWh
capacity granularity 1:  1 mWh
capacity granularity 2:  1 mWh
model number:            42T4572
serial number:            6175
battery type:            LION
OEM info:                SONY

Cemu ma pak clovek verit.

a vcem je problem? vzdyt oboje ukazuje to same

[pele]

Ptal jsem se na vydrz baterie, nerikal jsem ze se mi neco nezda na parametrech baterie.

U me se totiz vydrz baterie pohibuje mezi 1,5 a 1,9 hodiny (v orig. Vistach co tam byly to bylo kolem 3,5h).

[kozzi]

aha tak to jo. No a mas spravne rozchozene veci jako snizovani frekvence procesoru atd?

[pele]

Jop, procesor normalne snizuje frekvenci.

[tomvec]

Je to lehce mimo mísu ale... Mám ThinkPad T41 + lehce jetou baterku a s Ubuntu 8.10 2h35m. Nyní mám Ubuntu 9.04 (stále ve vývoji) a před 14-ti dny 1h40m a dnes 2h. Za těch 14 dnů několik upgade jádra, acpi atd. Přitom řízení frekvence "fungovalo" pořád. Jo, ale mezi tím jsem přidal ram, vestavěné bt a vyměnil minipci wifi za abg, což mohlo mít vliv na celkovou spotřebu, přesto se výdrž zlepšuje.

[Fluttershy, yay!]

Jsem na tom podobně. Dell Latitude D400: s openSuSE 11.1 výdrž 2,75 hodiny; s Ubuntu 8.04 je 2,2 hodiny.

Ja mam R500 ale asi jinou baterku:

present:                 yes
design capacity:         51830 mWh
last full capacity:      50900 mWh
battery technology:      rechargeable
design voltage:          10800 mV
design capacity warning: 2545 mWh
design capacity low:     200 mWh
capacity granularity 1:  1 mWh
capacity granularity 2:  1 mWh
model number:            42T5233
serial number:             859
battery type:            LION
OEM info:                Panasonic
 

S Kubuntu mi vydrzi klidne aj 3 hodiny.

[pele]

Parametry jsou stejne, jen jiny vyrobce.

Mohl si poslat baliky ktere mas nainstalovane a mohly by se tykat acpi, powersave a dal uz me nic nenapada.

Mám stejný problém, baterka mi v openSUSE 11.1 vydrží asi jeden a půl hodiny. Ve Vistách vydrží spoň dvakrát déle.. Už se ti podařilo přijít na to čím to bylo?? Používám Kde4.2, takže možná je problém v powerdevilu..

[pele]

Bohuzel zatim ne, pouzivam GNOME (Debian), ale v Ubuntu to udajne funguje.

[vencour]

A co Ti píše cpufreq-info, kolik Ti to žere ... cat /proc/acpi/battery/BAT0/state ?

[pele]

Hmm tak /proc/acpi/battery vubec nemam. Ale Powertop pise obrovskou spotrebu:

300.3W (0.2 hours) (long term: 25.1W,/2.0h)

Tento stav nastal asi po 2 minutách od doby, kdy jsem odpojil zdroj. Present rate pořád rostl.. 

cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          discharging

Toto už je zase s adaptérem:

Je možné, že by za tento problém s výdrží baterky mohl ovladač grafické karty radeonhd?

[MrPaveL]

A co si stáhnout(nainstalovat) program Powertop, který ukaže co jak má velkou spotřebu atd... ?

Má to i tipy na snížení spotřeby.

[orphus]

To jsem již zkousel, ale bohužel to moc nepomohlo Ale díky za radu!

[orphus]

Problem je u me vyresen. Za malou vydrz baterky mohl ovladac radeonhd, ktery jeste nejspis nema poradne udelany power management. Po nainstalovani ovladace fglrx baterka (podle power manageru) vydzi 3 az 4 hodiny..
