Managing Power 3-3
Initializing the Battery Pack
You need to initialize when the actual operating time of a battery pack is
much less than expected.
To initialize the battery pack, fully charge, then discharge completely by
changing the Windows Power Plan to High Performance (tap the icon
in the Windows system tray) and leave the AC adapter unplugged.
Recharge the battery pack completely by plugging in the AC adapter.
Checking the Battery Level
NOTE: Any battery level indication is an estimated result. The actual operating time can
be different from the estimated time, depending on how you are using the tablet
computer.
You can check the approximate battery level using the battery meter
function of the operating system. To read the battery level, tap the icon
in the Windows system tray.
NOTE: Upon replacing the battery pack, the reading on the battery meter is not
accurate. Windows will automatically do an update every 10 seconds to get the latest
correct reading.
Replacing the Battery Pack
If you rely on battery power for a long period of time, consider
purchasing an additional set of batteries from your dealer to use for
backup.
To replace the battery packs, follow these steps:
1. Close open applications and shut down the tablet computer.
2. Make sure that the tablet computer is not connected to AC power.
3. Use the Phillips screwdriver end of the stylus, or use a small #1
Phillips head screwdriver, to remove the two screws securing each
battery pack and then lift out each battery pack.
4. Fit the replacement battery packs into place and secure each with the
two screws. Do not over tighten.
