Troubleshooting Your Computer
What do I do if my computer won't start?
 Make sure the computer is securely plugged into a power source and turned on. Make sure the power indicator
shows the power is on.
 Make sure the battery is inserted properly and charged.
 Make sure the floppy disk drive (if applicable) is empty.
 If the computer is plugged into a power strip or uninterruptible power supply (UPS), make sure the power strip or
UPS is turned on and working.
 If you are using an external display, make sure it is plugged into a power source and turned on. Make sure the
brightness and contrast controls are adjusted correctly. See the guide that came with your display for details.
 Disconnect the AC adapter and remove the battery. Wait one minute. Reattach the AC adapter and reinsert the
battery. Turn on the power.
 Condensation may cause the computer to malfunction. If this occurs, do not use the computer for at least one hour.
 If the computer still does not turn on, follow these steps:
1. Unplug the power cord and remove the battery.
2. Use a thin, straight object (such as a paper clip) to press the reset button.
3. Reinsert the power cord and the battery.
4. Turn on the computer.
What do I do if a BIOS error appears when my computer starts?

Enter.
4. Press the Right Arrow key to select the Exit tab, and then press the Down Arrow key to select Get
Default Values. The message Load default values for all SETUP items appears.
5. Press Enter. The Setup Confirmation window appears.
6. Select Yes, and press Enter.
7. Select Exit (Save Changes), and press Enter. The Setup Confirmation window appears again.

If this occurs on a regular basis, contact Sony Computing Support ( http://www.sony.com/pcsupport ).
What do I do if the message "Operating system not found" appears when my computer starts, and why won't
Windows start?
 Make sure the computer does not have a "non-bootable" floppy disk in the floppy disk drive (if applicable).
 If a non-bootable floppy disk is in the drive:
1. Remove the floppy disk.
2. Restart the computer and confirm that the Microsoft ® Windows ® operating system starts properly.
