Thecoolingmoduleisconnectedtothesystemboard.Ifthecoolingmodulemalfunctions,
theremaybeabadconnectionbetweenthecoolingmoduleandthesystemboardoreither
mightbefaulty.
DisassemblethecomputerfollowingthestepsdescribedinChapter4andperformthe
followingchecks:

Check1 Makesurethecoolingmodulehasbeenfirmlyconnectedtotheconnector
onthesystemboard.Alsomakesurethatthetapeisnotstucktoanypart

thenreturntoProcedure1.Ifthereisstillanerror,performCheck2.
Check2 Thecoolingmodulemaybefaulty.Replaceitwithanewonefollowingthe
stepsinChapter4.Ifthecoolingmoduleisstillnotfunctioningproperly,
performCheck3.
Check3 Thememorymaybedefective.Replacethememorymodulewithanew
onefollowingthestepsdescribedinChapter4.Iftheproblempersists
performCheck4.
Check4 TheCPUmaybefaulty.Disassemblethecomputerfollowingthesteps
describedinChapter4andreplacetheCPUwithanewone.
