Scrolling.

"Testing the Hardware" on page 51.

Performance problems

For best performance with Windows XP, your notebook should have at least 128 MB of
memory (RAM).
If the notebook stops responding
• Press Ctrl+Alt+Del to end the application that is not responding.
• Press and hold the power button for at least four seconds to turn off and reset the
notebook. Then press the power button again to turn the notebook back on.
• If nothing happens, use a pen or straightened paper clip to press the reset switch on
the back of the notebook. Then press the power button to turn the notebook on.

Power and battery problems

If the notebook turns off immediately after it turns on
• Battery power is probably extremely low. Plug in the AC adapter or insert a charged
battery.
If the notebook keeps beeping
• The notebook beeps repeatedly when battery power is low (you can set this option in
Power Options in Control Panel). Save your work, turn off the notebook immediately,
and insert a charged battery or plug in the AC adapter.
If the battery doesn't charge
• Make sure the AC adapter is fully plugged into the power source and the notebook,
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.
