Sofeware and laptop battery life
whether your laptop runs three or four hours on a full charge with no extra messing around, or whether it dies in less than an hour, there are ways of extending the battery life like pa3107u-1brs through software settings. This notebook came equipped with a number of profiles optimized for different tasks. These are shown above, and for the main part, they are designed for the computing task, rather than for the extending the battery life like toshiba satellite a75 battery life to the maximum. In other words, they assume that you want DVD playback to proceed without any stumbles, and that you’d never want your hard drive to spin down or video output to wink off during a presentation. In none of the profiles to they drop the CPU processing speed (see graphic to the left) below the halfway point, 3 on a scale of 1 to 5. The settings they are most willing to sacrifice are the LCD brightness and the cooling method. Lower LCD brightness certainly extends battery life such as pa3383u-1brs a little but it’s so easy to manually adjust the LCD brightness from the keyboard that I don’t worry about getting it right in the profiles. In fact, when I use my notebook outside during the day, I usually find I have to run the LCD brightness up to the maximum (tapping Fn-F7 a few times) just to see.
