Maximize the performance of Toshiba PA3534U-1BAS Battery
There are several steps you can take to help you get maximum performance from your toshiba pa3634u-1bas battery:
1、Prevent the Memory Effect – Keep the pa3534u-1bas battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion toshiba pa3534u-1bas batteries which do not suffer from the memory effect.
2、Keep the toshiba laptop Batteries Clean – It’s a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.
3、Exercise the Battery – Do not leave the toshiba battery pa3534u-1bas dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a laptop battery has not been used for a long period of time, perform the new battery break in procedure described above.
4、Battery Storge- If you don’t plan on using the toshiba pa3534u-1bas battery (compatible with toshiba satellite a200 battery, toshiba equium a200 battery) for a month or more, store it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-ion toshiba batteries will self-discharge during storage; remember to recharge the batteries before use.

Increasing Toshiba Satellite A200 battery life under Linux

Introduction
This guide with provide you with tips to increase your toshiba laptop battery life under Linux when running on a laptop computer.
Tips
Use kernel with dynamic ticks
Since kernel 2.6.21, Linux includes a feature called dynamic ticks. Without getting too technical, the kernel reduces the number of ticks initiated when the system is idle, slightly reducing the cpu usage at this time and therefore extending toshiba a200 battery life. Fedora 7 has this feature on by default.
Ensure ACPI is enabled
Not so much a problem anymore as manufacturers are more actively checking that their ACPI implementations work under Linux but you should check that ACPI support is enabled. Without it you will get terrible power management and greatly reduced battery life. You can check if ACPI is enabled and running properly by typing dmesg in the console. If it is not working a kernel or BIOS update may fix the issue, if not then look up your laptop on these pages for more details.
Use CPU power saving
Most modern processors can dynamically reduce and increase their clock speeds. A utility is needed to do this such as cpufreqd or powernowd. My personal recommendation is powernowd, it is a simple program but works very well. These two utilities are included with most Linux distributions.
Blank screen when idle
A simple tip. Set the power settings to blank the screen when idle for a few minutes. The LCD display is one of the main consumers of power and so turning it off when not needed increases toshiba satellite a200 battery life greatly.
Use PowerTOP
Intel have developed a utility called PowerTOP. It’s aim is to see which applications on your system are using processing power and thus consuming extra battery. PowerTOP is starting to be included with many Linux distributions and you can also get it from the PowerTOP website.
