hibernace - spotreba energie

[wdolek]

vzdy sem zil v domeni, ze kdyz uvedu system do stavu “hibernace” vse se ulozi na disk a pocitac se kompletne vypne. nasvedcoval tomu i prubeh vypinani - trvalo necelou minutu za neustaleho svitu HDD LEDky… (ostatne tak se pocitac choval i pri spusteni)

rano sem pocitac spustil, a koukam

1. uptime je navysen o dobu, co mel system hibernovat - no to bych jeste prekousl…, ale
2. baterie notebooku byla vybita o takovych 10%

vyvstava tedy otazka co delam spatne, ze hibernace neni hibernaci?

(btw, prijde mi ze suspend do RAM zere uplne stejne (nebo jen o trochu mene) nez kdyz pocitac normalne bezi - to asi take neni uplne koser, ne?)

Lenovo R400…

uspaní do RAM spotřaba něco kolem 5W je uplně normální . Na disk stav vypnutého PC.
Jinak koukni do /var/log/pm-suspend.log

vaca: jiste, do RAM pocitac spotrebovava kvuli udrzeni vecicek v pameti - to chapu, ale ta hibernace?

nechal sem to v hibernaci hodinu, a za tuto hodinu pri odpojenem zdroji se baterie vybila cca o 1% (coz odpovida 1% za hodinu - kdyz sem to nechal hibernovat vcera vecer a rano to probudil, vybito bylo 10%). jeste muzu zkusit extremni pokus - hibernovat a vyndat baterii, schvalne co se stane

v “power history” sem po probuzeni navic nasel jakousi krivku, ktera ackoliv to bylo v hibernaci, neukazovala nulovou spotrebu …

a sam ted nevim, jestli to hibernuje nebo spi - kdyz uspim pocitac do RAM, tak mi tu na nem sviti ledka mesice. kdyz hibernuji, vse se tvari jako ze je vypnute…

[covex]

Hibernace vypina, uptime procesu se tim ale neprerusi, ten se inicializuje pri startu systemu, pri probuzeni z hibernace proste jen proces pokracuje kde skoncil, pocatek je urcen datumem. Je to vec kterou bych se moc nezaobiral.

Co se tyce te spotreby tak je to divne. Zkus tu baterku klidne vyndat. Samozrejme baterka se i za normalnich okolnosti samovolne vybiji, 1%/h ale je dost (zkousel si to porovnat se shutdownem?). Jedine co me napada je, ze Linux pri hibernaci nevypne nejake zarizeni typu wifi, bluetooth nebo jinou blbost. Napr. u stolnich PC dochazi i po hibernaci nebo poweroff k tomu, ze je porad napajena sitova karta, nebo jine periferie, ktere musi byt pripravene pro WOL apod. udalosti. Prijde mi to ale divne, protoze u notebooku jsem to snad este nevidel.

[wdolek]

covex: no jak ja ale neco takoveho zjistim? ja sem linuxovy zacatecnik, takze nemam nejmensi zdani, co kde, jak a proc. v logu sem si vsiml, ze pri hibernaci to u jedne polozky pise neco jineho, nez “success”

/usr/lib/pm-utils/sleep.d/75modules hibernate hibernate: not applicable.

co to ale je se mi vypatrat nepodarilo.

a jinak skutecne shutdown si drzi stejnou kapacitu baterky … no nezkousel sem to dele jak 2 dny (kdy sem musel ntb nechat nekde), ale vybiti zadne (nemeritelne). cili skutecne dochazi k necemu nehezkemu pri te hibernaci a neni to chyba baterie.

[covex]

Zjistit to jde asi jedine experimentovanim.

Pohledem do zmineho souboru jsem zjistil, ze se v nem ukoncuje cinnost nekterych ovladacu, pred prechodem do hibernace nebo suspendu. Vzhledem k tomu ze zrejme nemas zadne definovane, tak se proste nic nedeje.
To se samozrejme da zmenit, nicmene nejdriv vych kontroloval takove evidentni veci jako ze ti nezustane zapnute podsviceni displaye (display je sice cerny, ale ve tme porad zari).

[wdolek]

covex: no muzu rict, ze po hibernaci se pocitac skutecne tvari jako uplne vypnutej - tj podsviceni je vypnute, mechanika je take vypnuta :D, ani zadne LEDka nesviti, … at mackam co chci tak se nic nedeje - takze system je urcite haltlej… uz me toho moc nenapada …
experimentovani - kdybych tak vedel s cim si pohrat :((
