[Bug 518705] Re: 9.10 - Toshiba Satellite L30-113 freezes when on battery power, when AC is plugged out

[Thomas Lenarz]

I experience exactly the situation described in this bug.
However, the laptop is a ASUS X51R:

When battery powered, the GUI of Ubuntu freezes (possibly problem with
power-management). With AC supply no problem occurs.

Hardware:

Laptop ASUS X51R
CPU Celeron M520
Graphics: ATI Radion Xpress 1100

Ubuntu Versions: 9.10, 10.04 RC (latter from Live-CD)

-Hangup happens when booted shortly after starting up X. Don't get to sign-in dialog.
-If AC power is disconnected after boot up (Gnome active). GUI freezes within seconds.
-[AltGr][SysReq][k] does not get the system responsive again.

Using boot option acpi=off results in booting up and using the system is
fine with battery. However power-management functions are not present.

Thanks a lot
Thomas
