>>Centrino I would _assume_ that this being a centrino, it uses the newer power management specs -> ACPI. There's a lot of news about ACPI out there. Depending on your laptop model, you may find some pointers on www.tuxmobil.org or www.linux-laptop.com (This address I'm not too sure) Mind I ask what laptop you're using? Dell? I'm on a D600. (actual specs can be found from my previous post 1 or 2 days ago). I'm making a complain on the battery life. 2.30 hours (3 hours on WindowsXP) and it's dead! What about yours? ACPI is also not enabled by default in RH ( I don't know about others) stock kernel.

Is apm support limited to the older chips? thanks steve -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list
