Screen black (no backlight), wifi no hardware installed, clock resets

Hi all,

Which part could be responsible for all 3 of these issues on my 2011 MBP 17":

  • Screen feed black & no backlight, connecting external display via thunderbolt works
  • Wifi displays "no hardware installed"
  • System clock is set wrong and keeps resetting

Everything else works just fine including bluetooth, keyboard + light, sound + chime, power, ethernet, USB.

I tried PRAM & SMC resets, disconnecting battery, baking the logic board & reseating connections under the hood to no avail.

Thx!

The clock is a function of the PRAM capacitor.

BAKING THE LOGICBOARD?" That was probably the dumbest thing you've hopefully done all month. Ever even baked cookies? Were they crispy or soft? You may have destroyed any chance at repair. Please give us the exact year and model number. Please start here and post your results: http://www.coconut-flavour.com/coconutba...

Thanks for quick response. Yes, I realize that's not very high tech, I more like "dried it" for 5 min in oven at lowest setting. But that worked for my malfunctioning iPhone twice in the past. Either way, MacBook boots just as before after the baking.
