Standby mode:
Page 125.
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.
When the computer is powered with battery power, the computer
turns power off to the PC Card, and communication stops for
communication PC Cards, so the duration of suspend mode is
longer.
If communication for a PC Card is not reestablished after
resuming normal operation, remove and then reinstall the PC
Card before restarting the system or application program. For
other kinds of PC Cards, if the PC Card or computer does not
operate, restart the application or computer.
Note:
You must set the Ring Indicator
option in the ThinkPad Features
program so the computer
automatically resumes normal
operation.
For OS/2 or Windows:
1. Click on the battery icon
(
) in the ThinkPad
view.
2. Click on the
suspend/hibernation/resume
option icon (
); then
select the ring indicator
option.
