Troubleshooting Techniques
Don't touch the touch pad while the computer is rebooting or resuming from Standby
mode. If this happens, try the following: press a key on the keyboard to restore
normal operation, or suspend and resume operation using the power button.
If an external mouse is connected, the built-in pointing devices are normally disabled.
You can change this setting with the BIOS Setup utility—see "To run the BIOS Setup
utility" on page 48.
Restart the computer: click Start, Turn Off Computer (or Shut Down), Restart.

Performance Problems

For best performance, your computer should have at least 128 MB of memory (RAM).
If the computer stops responding
Press CTRL+ALT+DEL and use Task Manager to end the application that is not
responding.
Press the power button for at least 4 seconds to turn off and reset the computer. Then
press the power button again to turn the computer back on.
If nothing happens, insert the tip of a ballpoint pen into the reset button on the bottom
of the computer. Then press the power button to turn the computer back on.

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 or insert a charged
battery.
If the computer keeps beeping

Save your work, shut down Windows 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 computer,
and that the light on the adapter is on.
