How to Reset an IBM T43P Battery

Over time, a laptop's charge time typically gets shorter. It is a good practice to fully discharge your laptop battery before you plug the charger in, but doing so is not always feasible. If your IBM ThinkPad T43P battery barely holds a charge, run a system battery gauge reset, which can lengthen the life of an old battery. The reset can take up to six hours, but it's an automatic process once you initiate it, so you can leave the laptop while you go about other tasks.

• 1

  Plug the power adapter into the IBM T43P, start the computer and ensure the battery is connected. If the computer is already started, close all open programs.

• 2

  Double-click the battery icon in the bottom right corner of the screen (Windows taskbar). The "Power Manager" window will appear. Alternatively, can click "Start," "All Programs," "Access IBM" and click "Power Manager."

• 3

  Select the "Battery Information" tab at the top of the window.

• 4

  Click the "Perform Reset" button in the "Battery gauge reset" section, near the bottom of the window. The "Battery Gauge Reset" dialog box appears.

• 5

  Click "Continue." Allow the computer to perform the battery reset procedure, which requires fully charging, discharging, then recharging the battery.
