Procedure￿1￿Test￿Program￿Check￿

Execute￿the￿Fan￿On/off￿test￿program￿available￿as￿part￿of￿the￿maintenance￿test￿program.￿￿This￿ test￿program￿checks￿the￿cooling￿module.￿￿Insert￿the￿diagnostics￿bootable￿CD￿in￿the￿ computer's￿CD,￿turn￿on￿the￿computer￿and￿run￿the￿test.￿￿See￿Chapter￿3￿for￿information￿on￿how￿ to￿perform￿the￿test.￿

Procedure￿2￿Connector￿Check￿and￿Replacement￿Check￿

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:￿￿
