Nedavno mne muj novy laptop Lenovo ThinkPad E16 gen3 (AMD Ryzen7, 32 GB RAM) zaskocil extremnim zpomalenim. Myslim, ze to bylo v souvislosti s tim, ze jsem jej (snad asi poprve) pouzival delsi dobu jen na baterky. Vetsinou doposud fungoval pri soucasnem pripojeni napajeciho adapteru, nebo monitoru, ktery ma PD a tak slouzi jako zdroj take.

Po ukonceni prace jsem pouzil suspend jako obvykle. Druhy den pak bezel jako zpomaleny film. Utilita cpupower ukazovala governor policy powersave a frekvence jednotlivych jader jen stezi prelezla pres 500 MHz, pricemz minimum je 400 MHz a maximum cca 5,1 GHz. Spustene tri okna Firefoxu s nekolika zalozkami a load se blizil k 10. Co bylo take zajimave je, ze system nedetekoval pritomnost baterie - inxi -B nevypsalo vubec nic.

Reboot, zmena governor policy na performance a ani nastaveni minimalni frekvence na 3,3 GHz nic zasadne nezmenily. Zkousel jsem i predat jadru cpufreq.default_governor=performance jako parametr pri bootu pres GRUB. Zvlastni bylo, ze pocitac byl zabrzdeny i kdyz jsem otevrel BIOS. Zkousel jsem projit nastaveni, ale ani tam jsem nenasel nic co by situaci zmenilo.

Nakonec jsem restartoval, spustil BIOS, zvolil odpojit baterii, rozsrouboval laptop a baterii na 10+ minut fyzicky odpojil. Po opetovnem slozeni a zapnuti pocitac opet bezi jako hodinky...

Zajimalo by mne co si o tom myslite, zda jste se uz s necim takovym potkali a jak se situaci podarilo vyresit. Idealne pak rada jak obnovit puvodni funkcnost bez rozebrani pocitace a odpojeni baterie.

Pouzivam distribuci Debian Trixie (13.3) s distribucnim jadrem 6.12.73.
