http://forums.fedoraforum.org – Hi there, after installing Fedora 17 plus latest updates on my new laptop I had an estimated Battery-Time of roughly 2 hours (display dimmed to minimum, wlan on, internet surfing with chrome). I tried to increase the Battery-Time by doing the following: modified fstab (I am using an Intel 520 SSD, no swap drive since I have 16gb mem): Code: /dev/mapper/luks-ad7f76c3-2de3-4bd3-a17b-a583e8493b26 /                      ext4    defaults,noatime,discard        0 1 UUID=f8ac4308-35bb-4b45-a340-8cf8c77edf61 (HowTos)
