Troubleshooting Your Computer

Performance problems

For best performance with Windows 2000 or XP, your computer should have at least 96 to 128 MB of memory (RAM).

If the computer stops responding

•Press CTRL+ALT+DEL to end the application that is not responding.

•Slide and hold the power button for at least four seconds to turn off and reset the computer. Then press the blue sleep button to turn the computer back on.

•If nothing happens, insert a straightened paper clip into the system-off switch on the computer’s left side. Then press the blue sleep button to turn the computer back on.

•If the computer is docked, reset the expansion base—see “To reset the computer” on page 29.

Power and battery problems

If the computer turns off immediately after it turns on

•Battery power is probably extremely low. Plug in the AC adapter, insert a charged battery (if undocked), or plug in a secondary battery (if docked).

If the computer keeps beeping

•The computer beeps repeatedly or displays a warning when battery power is low. Save your work, shut down the computer immediately, and insert a charged battery or plug in the AC adapter.

If the main battery doesn’t charge

•Make sure the AC adapter is fully plugged into the power source and the computer or expansion base, and that the light on the adapter is on.

•If you’re using a power strip, remove the AC adapter from the power strip and plug it directly into a wall outlet.

•Make sure the battery is fully installed and locked in place.
