Page 41

Hibernation mode

In hibernation mode, the following occurs:

•The system status, RAM, VRAM, and setup data are stored on the hard disk.

•The system is powered off.

If you have defined one of the following actions as the event that causes the system to go into hibernation mode, perform that action.

•Closing the lid.

•Pressing the power button.

Also, the computer goes into hibernation mode automatically in either of the following conditions:

•If a “hibernation time” has been set on the timer, and if the user does not do any operation with the keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive within that time.

•If the timer conditions are satisfied in suspend mode.

When the power is turned on, the computer returns from hibernation mode and resumes operation. The hibernation file in the boot record on the hard disk drive is read, and system status is restored from the hard disk drive.

Symptom-to-FRU index

This section contains the following information:

•“Numeric error codes” on page 36

•“Error messages” on page 37

•“No-beep symptoms” on page 37

•“LCD-related symptoms” on page 37

•“Intermittent problems” on page 38

•“Undetermined problems” on page 38

The symptom-to-FRU index in this section lists symptoms and errors and their possible causes. The most likely cause is listed first, in boldface type.

Note: Do the FRU replacement or other actions in the sequence shown in the column headed “FRU or action, in sequence.” If replacing a FRU does not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU.

This index can also help you determine, during regular servicing, what FRUs are likely to need to be replaced next.

A numeric error is displayed for each error detected in POST or system operation. In the displays, n can be any number.

If no numeric code is displayed, check the narrative descriptions of symptoms. If the symptom is not described there, go to “Intermittent problems” on page 38.

Note: For a device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.
