Kernel module ideapad_laptop causes strange error messages while running on battery. This error message doesn't occur, when I plug in the power supply.

The problem also occurs while using older kernel versions.

I can confirm that this problem also occurs using newer kernels too.

The laptop model is different but the problem is exactly the same using the kernel 3.17.3-1-ARCH.
