The￿Bluetooth￿antenna￿wire,￿Bluetooth￿module￿or￿system￿board￿may￿be￿the￿reason￿of￿a￿

Bluetooth￿fault.￿Any￿of￿these￿components￿may￿be￿damaged.￿To￿determine￿if￿the￿computer’s￿

Bluetooth￿is￿functioning￿properly,￿perform￿the￿following￿procedures.￿Figure￿2-16￿outlines￿the￿

process.￿Start￿with￿Procedure￿1￿and￿continue￿with￿the￿other￿procedures￿as￿instructed.￿

Procedure￿1:￿ Diagnostic￿test￿

Procedure￿2:￿ Connector￿and￿replacement￿check￿

Procedure￿1￿ Diagnostic￿test￿

Run￿the￿Diagnostic￿Program,￿which￿will￿automatically￿execute￿the￿Bluetooth￿device￿check.￿￿ Refer￿to￿Chapter￿3.￿Tests￿and￿Diagnostics￿for￿more￿information￿PLS￿Use￿windows￿application￿ to￿check￿device￿can￿work￿fine￿or￿not.￿

If￿an￿error￿is￿located,￿go￿to￿Procedure￿2.￿￿If￿an￿error￿is￿not￿located,￿the￿Bluetooth￿system￿is￿ functioning￿properly.￿

Procedure￿2￿ Connector￿and￿replacement￿check￿

The￿Bluetooth,￿antenna￿module￿or￿system￿board￿may￿be￿disconnected￿or￿damaged.￿￿

Disassemble￿the￿computer￿following￿the￿steps￿described￿in￿Chapter￿4,￿Replacement￿

Procedures,￿and￿perform￿the￿following￿checks.￿

￿

Check￿1￿ Make￿sure￿that￿the￿Bluetooth￿antenna￿is￿firmly￿connected￿to￿the￿Bluetooth￿module￿ (refer￿to￿Chapter￿4￿for￿instructions)￿and￿that￿the￿Bluetooth￿FFC￿is￿securely￿slotted￿ into￿the￿system￿board.￿If￿the￿problem￿persists,￿go￿to￿Check￿2.￿

Check￿2￿ Check￿that￿the￿Bluetooth￿communication￿switch￿is￿turned￿to￿“On”,￿then￿make￿sure￿ that￿the￿communication￿LED￿on￿the￿left￿panel￿is￿lit.￿If￿the￿LED￿is￿lit￿but￿the￿ Bluetooth￿function￿is￿still￿faulty,￿the￿antenna￿module￿may￿be￿damaged.￿Replace￿ with￿a￿new￿antenna￿following￿the￿steps￿in￿Chapter￿4,￿Replacement￿Procedures.￿If￿ the￿problem￿persists,￿or￿if￿the￿Bluetooth￿communication￿LED￿is￿not￿lit￿when￿the￿ Bluetooth￿communication￿switch￿is￿turned￿to￿“On”,￿go￿to￿Check￿3.￿
