IBM A22P, A21M, A22M, A21P, A20M, MT 2631 manual Hibernation mode

Related service information

vIf 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:

vPress the Fn key.

vOpen the LCD cover (only if you are using Windows Me and you entered standby mode by closing the LCD cover.)

vTurn on the power switch.

Also, the computer automatically returns from standby mode and resumes operation in either of the following events:

vThe ring indicator (RI) is signaled by a serial device or a PC Card device (Windows 2000 does not support the ring indicator (RI) resume by PC Card device.)

vThe time set on the resume timer elapses. In Windows 98, the Scheduled Tasks setting takes priority over the Resume on timer selection in the “Power Management Properties” window.

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.

Note for Windows NT

If you are using Windows NT in the default format, NTFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall Windows NT with FAT format.
