If the battery light is glowing after 20 minutes, let the computer continue charging the battery for at least another 20 minutes before you turn on the computer.

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. 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.

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.

If Something Goes Wrong

Resolving a hardware conflict

If the battery has completely discharged, it will not begin charging

immediately. Leave the AC adaptor and power cord/cable

connected, wait 20 minutes and see if the battery is charging.

If the battery light is glowing after 20 minutes, let the computer

continue charging the battery for at least another 20 minutes before

you turn on the computer.

If the battery light does not glow after 20 minutes, the battery may

have reached the end of its useful life. Try replacing it.

The battery appears not to power the computer for as long as

it usually does.

If you frequently repeat shallow charge and discharge, the battery

meter may become inaccurate. 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.

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
