197 If Something Goes Wrong Resolving a hardware conflict 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.
