SYMPTOMS
========

After you install Windows 95 on a computer that supports Advanced Power
Management (APM), the APM features in Windows 95 do not work.

CAUSE
=====

This behavior occurs if you are using a real-mode (NDIS 2) network adapter
driver in Windows 95.

RESOLUTION
==========

If one is available, use a protected-mode (NDIS 3.1) driver for the network
card. To determine whether a protected-mode driver is available for the network
card, follow these steps:

1. Use the right mouse button to click the Network Neighborhood icon and then
  click Properties on the menu that appears.

2. In the "The following network components are installed" box, click the
  network card installed in your computer.

3. Click the Properties button. If there is an "Enhanced mode (32-bit and
  16-bit) NDIS driver" option on the Driver Type tab, there is an NDIS 3.1
  driver for the network card. If this option does not exist on the Driver Type
  tab, contact the manufacturer of the card to determine whether updated
  drivers exist.

MORE INFORMATION
================

Windows 95 rejects all APM requests if an NDIS 2 network card driver is
installed. Windows 95 does this because the network mapping file (NDIS.VXD)
cannot know in what state the real-mode driver would resume upon resumption of
power.
