Hello,
I am running Ubuntu 13.04 AMD64 (daily, of course) on my Acer Aspire 5735 laptop. Although it runs swimmingly, I have an issues that I can't work out on my own. When my laptop shuts down because of the battery running out, I turn it on, but the POST screen does not show up. The computer then proceeds to shutting down after about 20 seconds, turns itself on again, does the same 20-second thing, then shuts down, but doesn't restart on its own. This happens even with the charger plugged in. I have to disconnect the charger, turn on the computer, and remove the battery while the computer is (not) POSTing.
It can't be the battery, because it happened before and after I bought a new one.

Thank you,
Retro Banana
