Using Power Management
Points to Consider for Suspend Mode
Consider the following before using suspend mode:
The computer can enter suspend mode when used with the
following operating systems:
– DOS Version 7.0
– OS/2 Warp Version 3
– Microsoft Windows 3.11 with DOS Version 7.0
– Microsoft Windows 95
Important
When you use Windows Version 3.11, ensure that Advanced
Power Management (APM) is installed according to the
instructions in “Installing Windows 3.11” on page 165.
Attached devices, such as a printer or serial device, stop running
when the computer enters suspend mode. When you resume
normal operation, the output might differ from what you expect,
because the device might be reset or lose its configuration
settings.
Sometimes you might want to use the computer with the LCD
closed—for example, when an external monitor and keyboard are
used. In such a case, turn on the computer with the LCD closed
or set the computer to not enter suspend mode when the LCD is
closed using the ThinkPad Features program.
When a power-on password is set and the computer resumes
normal operation by the ThinkPad Features timer or an incoming
call, only a blank screen is displayed. To display a power-on
password prompt, press any key or move your pointing device.

When the computer is powered with ac power and is using one
of the following IBM PC Cards, it enters standby mode:
– IBM 3270 Emulation Credit Card Adapter
– IBM Token-Ring 16/4 Credit Card Adapter
– IBM Credit Card Adapter for Ethernet
– IBM 5250 Emulation Credit Card Adapter
When other PC Cards are used and the computer enters
suspend mode, all application programs stop. Communication
also stops for communication PC Cards not listed above. For
some PC Cards, power to the PC Cards might also turn off.
