After a period of time, the battery will lose its ability to
perform at maximum capacity and will need to be replaced.
This is normal for all batteries. To purchase a new battery
pack, see your accessories information that shipped with your
computer, or visit the Toshiba Web site at
accessories.toshiba.com. Refer to this site often to stay
current on the most recent software and hardware options for
your computer, and for other product information.
For more information on maximizing battery power see
“Charging batteries” on page 108 .
Keyboard problems
If, when you type, strange things happen or nothing happens,
the problem may be related to the keyboard itself.
The keyboard produces unexpected characters.
A keypad overlay may be on. If the numlock light or cursor
control mode light is on, press
Fn and F10 simultaneously to
turn off the cursor control mode light or Fn and F11
simultaneously to turn off the numlock light.
If the problem occurs when both the keypad overlays are off,
make sure the software you are using is not remapping the
keyboard. Refer to the software documentation and check
that the program does not assign different meanings to any of
the keys.
You have connected an external keyboard and the
operating system displays one or more keyboard error
messages.
The keyboard you connected may be defective or
incompatible with the computer. Try using a different make
of keyboard.
