Important Notes
·
Only trained personnel certified by LG should service the computer.
·
Read the entire FRU removal and replacement page before replacing any FRU.
·
Use new nylon-coated screws when you replace FRUs.
·
Be extremely careful during such write operations as copying, saving, formatting.
Drives in the computer that you are servicing sequence might have been altered. If you selected an
incorrect drive, data or programs might be overwritten.
· Replace FRUs only for the correct mode.
· When you replace a FRU, make sure the model of the machine and the FRU part number are correct by
referring to the FRU parts list.
· A FRU should not be replaced because of a single, irreproducible failure. Single failures can occur for a
variety of reasons that have nothing to do with a hard ware 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 careful not to replace a non-defective FRU.
