Troubleshooting and Maintenance

Troubleshooting Your Computer

If the computer won’t boot from the floppy disk drive

•Make sure the floppy disk drive is selected as the boot device—see “To change the boot device” on page 28.

•If you’re using a USB floppy drive, use the BIOS Setup utility to make sure Legacy USB Support is enabled—see “To run the BIOS Setup utility” on page 118. If your computer also has a built-in floppy drive, use the BIOS Setup utility Boot menu to make sure the USB floppy drive is the first device under Removable Drive.

If the computer stops responding after booting

•Check whether you are connected to a TCP/IP network with no DHCP server. This can cause a long delay at startup because DHCP is enabled. Contact your network administrator to determine the proper TCP/IP configuration.

If the computer takes a long time to resume after being suspended

•The computer can routinely take a minute or more to resume if it has a network card installed. While the operating system is loading drivers and checking hardware and network connections, you will see a blinking cursor on your display. As soon as the hardware has been re-initialized, the Windows desktop will appear.

Wireless Problems

If you have problems with wireless 802.11 communication

•Make sure the wireless indicator light is on.

•If your computer includes Bluetooth capabilities, make sure wireless 802.11 communication is turned on. Click Start, All Programs, Utilities, Wireless Configuration, then click the 802.11 button if it’s not turned on.

•Make sure you are using the correct SSID and channel settings—see “To prepare for connections” on page 62.

•Make sure you are in range of an access point (for an infrastructure connection) or other wireless computer (for an AdHoc connection).
