The Basic CPU Tweak

The Basic CPU Tweak

Laptop Battery Optimization Guide (Basic)

This tweak will enable th eToshiba Satellite A65 Series Battery basic, built-in power-saving function in your CPU. Go to your Control Panel, and select 'Power Options". There are 3 settings that matter to you:

Home/Office Desk - This setting will disable'the power-saving features for your CPU only when the notebook is plugged in the AC adapter. When Home/Office Desk is set while running the battery, the CPU can still throttle down.

Portable/Laptop - This will enable PowerNow!, Cool&Quiet, or SpeedStep, if your CPU supports it. These technologies all clock down your CPU when not in use, thus saving you battery life while maintaining similar performance.

Max Battery - This setting is only useful when you are really desperate for battery life. By switching to this profile, the CPU will be set to the lowest setting, which should be around 600Mhz to 800MHz. This will severely hinder performance when needed, though.

Additional settings mentioned below will also improve your battery life.Toshiba Satellite 1900 Battery By setting the monitor or hard drive to turn off when not in use, you can also save battery power. Be sure to modify only the 'Running On Batteries' column.

Turn Off Monitor - This setting will turn off your monitor when not in use. Only turn this on if you won't need to look at your screen, eg if you're gone from the keyboard, or if you're only listening to music. However, if you are watching a movie, the monitor will still turn off after the allotted time has passed, making this a potentially annoying feature.

Turn Off Hard Disks - This setting turns off your hard drive(s) when not in use after the allotted time. This is rather useful, because many programs, when running, do not actually access the hard drive. However, setting it too low will prove an annoyance, because it takes a while for the hard drive to go from off to on.

System Standby - Again, like the previous settings, this will make your system go Toshiba Satellite A60-662 Battery, into Standby mode after the allotted time has passed. This is only useful if you'll be gone from the keyboard.

GPU Tweaks

Tweaking the Graphics Card

When performing basic 2D tasks, such as web browsing or other tasks, the speed/quality of the graphics card makes no difference. Therefore, it is in your best interest to turn down the power of the graphics card to increase battery life. The most effective way to accomplish this is to lower the clock speed of the graphics card core and memory. If you have integrated graphics, you have limited access, and can not perform ANY of the following tweaks.

Before you get started, you should find out what card you have by going to Control Panel -> Display -> Settings
