Re: [suse-laptop] Re: acpi related problem on ACER TM 4002WLMi running SuSE 9.2

Thanks Thomas!!! it did work perfectly!!!

I follow your steps, rebooted the laptop, and now I have an icon
telling me the battery is charging :-D the status is updated, and all
the menus are shown in the control centre-power control menus

I didn't get any strange messages, no funny behaviour, it was a
step-by-step procedure, just perfect!!!

I'll join the group you told me, I just hope they have patience with
my english, since my german is quite poor. I could only find a german
suse-laptop group :-/

best regards
Carlos
