Numeric Error Codes; Intermittent Problems - Lenovo ThinkPad Hardware Maintenance Manual

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 33.
Note: For a device not supported by diagnostic codes in the tablet, see the manual for that device.

Intermittent problems

Intermittent system hang problems can be due to various causes that have nothing to do with a hardware
defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be
considered only when a problem recurs.
When analyzing an intermittent problem, do the following:
FRU or action, in sequence
Checksum of the supervisor password in the EEPROM is
not correct. The system board should be replaced. Have
the tablet serviced.
Checksum of the Security settings in the EFI Variable
is not correct. Enter ThinkPad Setup to check Security
settings, Press F10 and then press Enter to restart the
system. If you still have a problem, have the tablet
serviced.
The access to EEPROM is failed. Have the tablet serviced.
The EEPROM checksum is not correct (block # 0 and 1).
The system board should be replaced, and the box serial
number needs to be reinstalled. Have the tablet serviced.
The EEPROM checksum is not correct (block # 4 and 5).
The system board should be replaced, and the Universally
unique identifier (UUID) needs to be reinstalled. Have the
tablet serviced.
The tablet turned off, because the battery is low. Connect
the ac adapter to the tablet and charge the battery.
The system configuration change has failed. Confirm
the operation and try again. To clear the error, enter the
ThinkPad Setup.
This message is displayed if you enter a wrong supervisor
password more than three times. Confirm the supervisor
password and try again. To clear the error, enter the
