• The system is powered off.

Note: If the computer enters the hibernation mode while it is connected to the dock, do not disconnect it

before resuming normal operation. If you do disconnect it and then try to resume normal operation, you will

get an error message, and you will have to restart the system.

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 after a period of inactivity specified in power

plan settings.

When the power is turned on, the computer returns from hibernation mode and resumes operation. The

hibernation file in the boot record on the solid-state drive is read, and system status is restored from the

solid-state drive.

Symptom-to-FRU index

This section contains following information:

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 36.

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

for that device.
