Related service information 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 X6 Tablet UltraBase, 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. v If you are using the APM operating system and have set the mode to Power switch mode [Hibernation], turn off the power switch.

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

drive
within
that
time.
v
If

and
then
the
computer
enters
the
power-saving
mode
automatically.
This
default
low-battery
behavior
is
independent
of

system;
so
if

the
low-battery
alarm,
the
computer
may
not
do
what
you
specified.
It
chooses
either
your
setting

by
a
serial
device
or
a

set
on
the
resume
timer
elapses.
Note:
The
computer
does
not
accept
any
input

enters
standby
mode.
Wait
a
few
seconds
before
taking
any
action
to
reenter
operation
mode.
