To enter standby mode, press Fn+F4.
Note: If you are using the ACPI operating system, you can change the action of
Fn+F4.
In certain circumstances, the computer goes into standby mode automatically:
v
If a “suspend time” has been set on the timer, and the user does not do any
operation with the keyboard, the TrackPoint
®
, the hard disk, the parallel
connector, or the diskette drive within that time.
v If the battery indicator blinks orange, indicating that the battery power is low.
(Alternatively, if
Hibernate when battery becomes low
has been selected in the
“Power Management Properties” window, the computer goes into hibernation
mode.)
Note for the APM operating system:
Even if you do not set the low-battery alarm, the charge indicator notifies you
when the battery is low, and then the computer enters the power-saving mode
automatically. This default low-battery behavior is independent of the operating
system; so if you have set the low-battery alarm, the computer may not do what
you specified. It chooses either your setting or the default setting, whichever is
appropriate.
If you are using the ACPI operating system, only the low-battery alarm is
available.
To cause the computer to return from standby mode and resume operation, do one
of the following:
v
Press the Fn key.
v
Open the LCD cover.
v
Turn on the power switch.
Also, in either of the following events, the computer automatically returns from
standby mode and resumes operation:
v The ring indicator (RI) is signaled by a serial device or a PC Card device.
v
The time set on the resume timer elapses.
Note: The computer does not accept any input immediately after it enters
standby mode. Wait a few seconds before taking any action to reenter
operation mode.
Hibernation mode
In hibernation mode, the following occurs:
v
The system status, RAM, VRAM, and setup data are stored on the hard disk.
v
The system is powered off.
Note: If the computer enters the hibernation mode while it is docked to the
ThinkPad Advanced Dock or ThinkPad Advanced Mini Dock, do not
undock it before resuming normal operation. If you do undock it and then
try to resume normal operation, you will get an error message, and you will
have to restart the system.
To cause the computer to enter hibernation mode, do any of the following:
v
Press the Fn+F12 keys.
