Mac Book Air A1466 EMC 2925 Logic Board no 820-00165 -A problem not getting ON, no green light appears on dc jack (magsafe) solved by replacing SMC chip. First I use Smc chip of 820-3437-b everything working fine but no sound come. Actual problem was on the board one wire circuit signal not coming out from Smc controller Io chip. The only solution of such problem to replace Smc Io chip with the same part no of Apple logic board because it is always programmed from apple manufacture.
