PCMCIA Network Power Management

When using a PC Card network adapter you might not be able to connect the computer to the network, and under Control Panel > System there is a yellow exclamation mark "!" next to the card.

Open your registry and find the key below.

Modify the value named "EnablePowerManagement" and change it to '0' based on the following:

* If the current value is '01 00 00 00' change it to '00 00 00 00' (Full Version).
* If the current value is '0x00000001 (1)' change it to '0x00000000 (0)' (Upgrade Version)

Restart Windows for the change to take effect.


Settings:
System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VCOMM]
Name: EnablePowerManagement
Value: (0 = disable, 1 = enable)
