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 27. • 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 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, Hewlett-Packard, Notebook, HP 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 64. • Make sure you are in range of an access point (for an infrastructure connection) or other wireless computer (for an AdHoc connection). • See "LAN Problems" on page 103. If you have trouble connecting to another computer in the Network Neighborhood or My Network Places • Wait a few minutes, and then press F5 to refresh the list of computers on the network. • Click Start, Search, Computers or People to locate the computer. 114 Reference Guide
