162 If Something Goes Wrong Resolving a hardware conflict The battery appears not to power the computer for as long as it usually does. If you frequently recharge a partially charged battery, it may not charge fully. Let the battery discharge completely, then try charging it again. Check the power options using the Power Management utility. Have you added a device, such as a PC Card or memory module, that takes its power from the battery? Is your software using the hard disk more? Is the display power set to turn off automatically? Was the battery fully charged to begin with? All these conditions affect how long the charge lasts. For more information on maximizing battery power, see "Maximizing battery life" on page 78. 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 numeric keypad or cursor control light is on, press Fn and F10 simultaneously to turn off the cursor control light or press Fn and F11 simultaneously to turn off the numeric keypad 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's 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. If you have a second keyboard, try it. If it works, the first keyboard may be defective or incompatible with your computer.
