Using Power Management
Considerations 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 or later
– OS/2 Warp Version 3 or later
– Microsoft Windows Version 3.11 with DOS Version 7.0 or
later
Important
When you use Windows Version 3.11, ensure that Advanced
Power Management (APM) is installed according to the
instructions in “Installing Microsoft Windows Version 3.11 or
Later” on page 233.
Approximately 1.5 hours are needed to recharge the battery in
suspend mode.
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 display 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 or hard disk password is set, you
need to enter your password to resume normal operation from
the ThinkPad Features timer or ring indicator. However, no
password prompt will be displayed; only a blank screen is
displayed.
