Considerations When Using a Power Management Mode When you use a power management mode, you need to consider a few points, especially if you are using the network. 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 - OS/2 Warp Version 4 - Microsoft Windows Version 3.11 with DOS Version 7.0 - Microsoft Windows 95 - Microsoft Windows 98 - Microsoft Windows NT Version 4.0 Important If you use Windows 3.1, ensure that Advanced Power Management (APM) is installed according to the instructions in "Notes for Reinstalling or Installing the Operating System" on page 29. 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 use the ThinkPad Configuration program to set the computer not to enter suspend mode when the LCD is closed. If the computer resumes normal operation by reaching the ThinkPad Configuration timer setting or because of an incoming call, only a blank screen is displayed. To display a power-on password prompt, press any key or move your pointing device. If you are using some communication cards and the computer is powered with ac power, your computer enters standby mode rather than suspend mode. Chapter 4. Using Your Computer with a Battery Pack 27

Considerations When Using a Power Management Mode
When you use a power management mode, you need to consider a
few points, especially if you are using the network.
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
–
OS/2 Warp Version 4
–
Microsoft Windows Version 3.11 with DOS Version 7.0
–
Microsoft Windows 95
–
Microsoft Windows 98
–
Microsoft Windows NT Version 4.0
Important
If you use Windows 3.1, ensure that Advanced Power
Management (APM) is installed according to the instructions
in “Notes for Reinstalling or Installing the Operating System”
on page
29.
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 use the ThinkPad Configuration program to set the computer
not to enter suspend mode when the LCD is closed.
If the computer resumes normal operation by reaching the
ThinkPad Configuration timer setting or because of an incoming
call, only a blank screen is displayed.
To display a power-on
password prompt, press any key or move your pointing device.
If you are using some communication cards and the computer is
powered with ac power, your computer enters standby mode
rather than suspend mode.
