Plugging in power supply crashes laptop, using 2.6.12-10-686.

[Fabian Deutsch]

I'm using a BenQ JoyBook 5100 G. Until the last kernel-image 2.6.12-10-686 update.

What happens:
After I plug in power cable to recharge my laptop, the screen goes black and it seems as if it is going into suspend mode ...
When pressing anykey the screen returns but with no clear picture and you cant use Ctrl+Alt+[1-5] to switch to a console.
The laptop doesn't react anymore.
This doesn't happen when I use the 2.6.12-10-386 kernel and it didn't happen before, as said.

I tested this on dapper/flight-3 and the behavior is quite similiar. The laptop goes into standby/suspend/supsed to disk mode but doesn't resume anymore (which he did when using breezy).

Similar or exactly the same? Does it suspend when you plug the power supply in?

[Fabian Deutsch (fabiand)]

Similar.
After i pluggin my power supply on:

* Breezy: It goes into suspend/standby (don't know how to gigure out what it does), but resumes when pressing a key on the keyboard.

* Dapper (F3): It goes into suspend/or what so ever, but doesn _not_ resume on a key press. You need the power button to turn it off and back on.

Addition:
The laptop only crashes (on Dapper F3), when the power supply is _not_ plugged in while booting.

Summary:
Dapper F3 crashes (goes into some mode, but doesn's resume) when plugging in a power supply, while being on battery.

Looks like a kernel issue, not acpi-support

Fabian,

Dapper has a new kernel. Does this still happen?

Thanks.

I'm having the same problem with Ubuntu 7.04, kernel 2.6.20-15-generic on a IBM T40 laptop. It seems like the problem goes away if I go to Power Management and change "When battery is critcally low" to "Do nothing". I guess there is a defect in the Power Management application so it think's there is no power left when the laptop is switching from battery to power supply.
