9.10 - Toshiba Satellite L30-113 freezes when on battery power, when AC is plugged out

[MapHtH]

I think that this has something to do with the kernel. I'm using the Ubuntu 2.6.31-19 Kernel. I keep my battery out of the laptop to preserve it. I plugged it in a few days back, and I noticed that Ubuntu won't boot. It either hangs on boot loading screen, or enters the UI and hangs there. When it enters the Gnome UI, I can't move the cursor, nothing responds, I have to forcefully shut it down. One guy had a similar problem, as I found via google (http://<email address hidden>/msg1966386.html), and he solved it by installing (at that time) the newest kernel update. This is very irritating as the battery can't be used at all.

Thanks for help

I have Toshiba A205-4567S and I can report the same problem not only on Karmic kernel but Lucid too. I even tried to run live Knoppix with kernel 2.6.32-17 but it freezed at the time the desktop started to load. On Hardy no problems at all. For sure this is a kernel bug but I am not very competent how to send a report to the proper developers.

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

Yesterday I tested a new release of Xubuntu 10.10 and the bug still exists.
When on battery power my laptop works for a minute or two and then just hangs on.
Reproducible even with live cd.

[Thomas Lenarz (tommesml)]

Test with Ubuntu 10.10 live CD on ASUS X51R failed as well.

I have the same trouble on Asus K50IE with ubuntu 10.10.
Ubuntu freezes in a few minutes after i plugged AC out.
