To understand power management limitations

Windows NT 3.51 is not Advanced Power Management (APM) aware or Plug and
Play compatible. This presents a challenge for mobile users who want to use
Windows NT with their portable computer. Be aware of the following limitations:
PC cards (PCMCIA) cannot be hot swapped into the OmniBook. Windows NT
does not support dynamic allocation of resources. PC cards must be inserted
into the unit before booting. The floppy disk drive and CD-ROM drive cannot be
hot swapped.
The operating system's clock is stopped when suspended and does not re-
synchronize with the hardware clock when resuming. When users resume, NT's
clock starts up exactly where it was when they suspended. Rebooting resets the
clock.
PC card sockets are not turned back on after resuming. PC cards are inoperable
after a true suspend then resume cycle. After a reboot the sockets are restarted.
The OmniBook's Display Off (pressing blue On/Suspend with ac inserted)
mode does not cause these symptoms, since only the display, keyboard, sound,
and mouse are turned off by the BIOS. The CPU and network cards are still
active and operating normally.
