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.
• To avoid lockup problems, avoid pressing Fn+F5 to switch display devices while
graphic-intensive applications are running. Also avoid turning off or suspending the
computer while such applications are running.
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
• The computer beeps repeatedly or displays a warning when battery power is low.
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.
• 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.
