Troubleshooting Your Computer 
48 Startup Guide 
If the touch pad or pointing stick doesn’t work 
•  Don’t move the pointer or 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. 
•  Suspend and resume operation using the sleep 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 52. 
•  Restart the computer: click Start, Shut Down (or Turn Off Computer), Restart. 
Performance Problems 
For best performance with Windows 2000 or XP, your computer should have at least 
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 
right side of the computer. Then press the blue sleep 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 
•  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.
