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.
• Pressing Fn+F4 keys.
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 hard disk drive is read, and system status is restored from the
hard disk drive.
Symptom-to-FRU index
This section contains following information:
•
“Numeric error codes” on page 34
• “Error messages” on page 35
• “No-beep symptoms” on page 36
• “LCD-related symptoms” on page 36
• “Intermittent problems” on page 37
• “Undetermined problems” on page 37
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 37.
Note: For a device not supported by diagnostic codes in the ThinkPad notebook computers, see the
manual for that device.
