Procedure￿1:￿ Diagnostic￿test￿

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

Procedure￿1￿ Diagnostic￿test￿

Run￿the￿Diagnostic￿Program,￿which￿will￿automatically￿execute￿the￿wireless￿LAN￿test.￿￿Refer￿ to￿Chapter3￿item￿A:￿CONFIG￿CHECK￿TEST”￿Test￿and￿Diagnostic￿for￿more￿information￿on￿ the￿program.￿

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

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

The￿wireless￿LAN￿antenna,￿wireless￿LAN￿unit￿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￿wireless￿LAN￿antenna￿is￿firmly￿connected￿to￿the￿Wireless￿ LAN￿module￿(refer￿to￿Chapter￿4￿for￿instructions)￿and￿that￿the￿wireless￿LAN￿ module￿is￿securely￿slotted￿into￿the￿system￿board.￿If￿the￿problem￿persists,￿go￿to￿ Check￿2.￿

Check￿2￿ Check￿that￿the￿wireless￿communication￿function￿is￿enable￿by￿BIOS￿setup￿or￿ FN+F8￿,￿and￿then￿make￿sure￿that￿the￿wireless￿communication￿LED￿on￿the￿front￿ panel￿is￿light.￿If￿the￿LED￿is￿light￿but￿the￿wireless￿LAN￿function￿is￿still￿faulty,￿the￿ antenna￿may￿be￿damaged.￿Replace￿with￿a￿new￿antenna￿following￿the￿steps￿in￿ Chapter￿4,￿Replacement￿Procedures.￿If￿the￿problem￿persists,￿or￿if￿the￿wireless￿ LAN￿LED￿is￿not￿light￿when￿the￿wireless￿communication￿function￿is￿enabled￿by￿ BIOS￿setup￿or￿FN+F8,￿go￿to￿Check￿3.￿

Check￿3￿ The￿wireless￿LAN￿unit￿may￿be￿damaged.￿Replace￿it￿with￿a￿new￿one￿following￿the￿

instructions￿in￿Chapter￿4.￿If￿the￿problem￿still￿exists,￿perform￿Check￿4.￿

Check￿4￿ The￿system￿board￿may￿be￿damaged.￿￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿
