windows, good battery life -> fedora, bad battery life
I am running Fedora Core 3 on my Sony Vaio PCG-K27 laptop. Before installing Fedora, i got about 4 hours of use out of my battery on windows.
Since switching to Fedora, running on battery power appears to deplete the battery to about 50% in half hour! (at least, according to Gnome's Battery Charge Monitor (2.8.0), and KDE's equivalent).
Also, when i plug-in or unplug the AC adapter, niether Gnome nor KDE realize i did so until i lot out and log in again (they continue to show it as running on battery or AC power and the % does not change).
Could this just be ACPI issues? Could Gnome and KDE just be misreading the battery's charge? If the battery is being depleted so fast- why? What can be done??
Thanks in advance
