Comment 42 for bug 989191

Simon, thanks for the suggestions, but they unfortunately did not work for me. I am running Ubuntu 14.04 on an ASUS Ux21 Series Ultra Slim. This bug has been an issue for me since getting this laptop. It is no longer a laptop as a result of the bug—I am forced to use it only when plugged in.

The suggested solution above did NOT work for me. I followed the steps exactly as described (included unplugging the battery for five minutes) but when I restarted the computer and then tried unplugging my laptop, the computer crashed and shut down immediately. The only possible difference I note between your setup and mine is that my grub file does not have a ".cfg" suffix.
