Understanding Plug And Play; Managing Pc Card Power - Compaq Armada 4200 Reference Manual

Understanding Plug and Play

If you are running Windows 95, you do not need to turn off the
computer before inserting or removing a PC Card. If the computer
is on, it will automatically configure most PC Cards. For example,
a modem/fax card is configured to a COM port, while a storage
card is assigned a drive letter. If the computer is turned off or is in
Suspend, the card will not be configured until the computer is
powered on.
If you are running Windows NT, turn off the computer before
inserting or removing a PC Card. Since Windows NT is not Plug
and Play, it can only recognize hardware configuration changes
(devices added or removed) during computer power-up.

Managing PC Card Power

PC Cards are power options in a small form factor. When PC
Cards are installed in your computer, they draw power from the
system even when they are not in use.
If you are running Windows 95, remove PC Cards when they are
not in use to conserve power, or you may turn off power to the PC
Card slots through Power Properties. If you are running Windows
NT, remove PC Cards when they are not in use to conserve power.
If you are operating the computer on a battery pack, disable power
to the PC Card slots to extend battery life. You can also turn off
power to the PC Card slot when the computer is in Suspend.
