Troubleshooting and Maintenance
Troubleshooting Your Notebook
If the notebook takes a long time to resume after being suspended
The notebook 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 reinitialized, 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 notebook includes Bluetooth capabilities, make sure wireless 802.11
communication is turned on. Select Start > All Programs > Utilities > Wireless
Configuration, then select the 802.11 button if it's not turned on.
Make sure you are using the correct SSID and channel settings.
Make sure you are in range of an access point (for an infrastructure connection)
or other wireless notebook (for an Ad Hoc connection).
When you log on to an 802.11 network via an access point, yet your notebook
cannot connect to network resources, your notebook may not have been
assigned an IP address. If the subnet mask for your wireless connection is
255.255.000.000, the network server did not assign an IP address to your
notebook, and you may have to release and renew your network IP address. If
this does not fix the problem, the access point may need to be rebooted.
If you want to change the SSID to a different value to connect to a different
access point, or if you want to change from Infrastructure mode to Ad Hoc mode,
you may first have to release and renew the internet IP address.
See "Local area network (LAN) problems" in this chapter.
If you have trouble connecting to another notebook in the Network
Neighborhood or My Network Places
Wait a few minutes, and then press F5 to refresh the list of notebooks on the
network.
Select Start > Search > Notebooks or People to locate the notebook.
