LG E500 With Ubuntu/Debian, ACPI/Power Management not working


I'm having a LG E500 (V.AP77V) laptop with these specs: Intel Core 2 Duo T8100 2.2GHz, 3GB DDR2, 250GB SATA HDD, ATI Mobility Radeon X2600HD 256MB, 15.4"

After installing Windows XP I also tried to install both Ubuntu and Debian Testing without success. The only way to boot the installer and the installed system is with acpi=off. Because this is a laptop I need power management functionality. Simple things like the gnome battery monitor doesn't work and if that doesn't work I guess I will be unable to use power saving functions.

So my questions is simple, am I able to install Ubuntu or Debian on this laptop and maintain the same functionality I have in Windows (battery monitor, cpu freq. scaling and such)?

Someone also told me to post my lspci along with my question and here it is:
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 671MX

    03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller (rev 01)
I appreciate all help I can get, post everything you can think of that may help me! This laptop would be perfect if I only could dual boot Windows and Ubuntu/Debian.
Thanks // rdj

I had the same problem. Just add nolapic_timer instead of acpi=off. It work just fine.


acpi, laptop, lg, management, power
