I've got a problem with Ubuntu 13.10 on my laptop Acer Aspire 5750ZG. It cannot recognize that it is running on laptop - there is no battery indicator, power consumption is very high.
Simply changing "System settings" - "power options" didn't help. I've found some related problems, but neither of them worked in my case.
Edit: I needed to set
acpi=off option to boot settings in grub for Ubuntu to work correctly - maybe this is the source of my problems?
