•Mechanicalhazards,suchaslooseormissinghardware
Todeterminewhetherthereareanypotentiallyunsafeconditions,usethefollowingchecklistatthebeginning
ofeveryservicetask.Beginthecheckswiththepoweroff,andthepowercorddisconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground
continuity for 0.1 ohm or less between the external ground pin and the frame ground.
b. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any
non-ThinkPad alterations.
7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or
other liquids, or signs of fire or smoke damage.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered
with.

Str tegy for repl cing FRUs
Before repl cing p rts:
Ensure that all software fixes, drivers, and UEFI BIOS downloads are installed before replacing any FRUs
listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before
completing the service action.
Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs:
•IfyouareinstructedtoreplaceaFRUbutthereplacementdoesnotcorrecttheproblem,reinstallthe
originalFRUbeforeyoucontinue.
•Somecomputershavebothaprocessorboardandasystemboard.Ifyouareinstructedtoreplaceeither

Importntnotes:
•Only certified tr ined personnel should service the computer.
•Before repl cing ny FRU, re d the entire p ge on removing nd repl cing FRUs.
•When you repl ce FRUs, it is recommended use new nylon-co ted screws.
•Be extremely c reful during such write oper tions s copying, s ving, or form tting. The sequence
of the drives in the computer that you are servicing might have been altered. If you select an incorrect
drive, data or programs might be overwritten.
•Repl ce FRU only with nother FRU of the correct model. When you replace a FRU, ensure
that the model of the machine and the FRU part number are correct.
•A FRU should not be repl ced bec use of single, unreproducible f ilure. Single failures can
occur for various reasons that have nothing to do with a hardware defect, such as cosmic radiation,
electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. If you
suspect that a FRU is defective, clear the error log and run the test again. If the error does not recur, do
not replace the FRU.
•Be c reful not to repl ce nondefective FRU.

Restoring the f ctory contents by using the product Recovery Disc Set
When the main storage drive is replaced because of a failure, no product recovery program is on the new
drive. In this case, the customer must use the Recovery Disc Set to recover the computer. Order the
Recovery Disc Set and the drive at the same time so that the customer can restore the computer to the
factory default settings by using the Recovery Disc Set after the new drive is installed.
Depending on the model, the number of recovery discs included in the Recovery Disc Set differs. To restore
the factory contents by using the product Recovery Disc Set, do the following:
