Veskere komponenty byly detekovany pri instalaci a funkcni (netestovan pouze softmodem). Funguje i acpi a setrici rezimy. Pro podporu freq. scaling je nutne nahrat modul p4-clockmod (standarne se nenahrava, trochu prodlouzi vydrz baterie).

Nejvetsi potiz byla s kompletnim rozjetim ACPI. Hibernace (na disk) funguje bez potizi ihned po instalaci. Vsecky setrici rezimy funguji dobre. Ale Suspend-to-ram nejede standardnim zpusobem kvuli videokarte.

Chcete-li pouzivat suspend-to RAM, je nutne vypnout DRI u X.org a pro suspend-to-ram pouzit nasledujici skript:

#!/bin/bash

/sbin/rmmod uhci-hcd
/sbin/rmmod ehci-hcd
/usr/bin/chvt 1
cat /proc/bus/pci/00/02.0 > /var/cache/video.config
echo -n mem > /sys/power/state
cat /var/cache/video.config > /proc/bus/pci/00/02.0
rm -rf /var/cache/video.config
/sbin/modprobe uhci-hcd
/sbin/modprobe ehci-hcd
/usr/bin/chvt 7

Poznamka ke zprovozneni zvukoveho vystupu v alse:

Je treba ztlumit (Mute) kanaly Headphone a Line Jack Sense, jinak se vsechny zvukove aplikace tvari, ze hraji, ale zadny vystup se nekona.

Jinak hardwarova tlacitka na hlasitost funguji bez problemu.

I kdyz jde o levny notebook, stale je to IBM. Kvalitni provedeni, tezky presne 3kg, coz neni v teto cenove kategorii zadna hruza. Funkcnost s trochou prace 100%. Da se sehnat za cca 21.000 Kc i s dani.

Provozujeme jej na Mandriva Linuxu 2005 LE (pro ni plati i postup zprovozneni), pouzity kernel je 2.6.11-i586-up-12mdk. S nahranym modulem p4-clockmod (viz vyse) a snizenym jasem displeje opravdu vydrzi cca udavanych 3.5 hodin na baterie.

POZN: presny model notebooku je 1843-xxx.
