Yesterday noon, I’ve closed my laptop without shutting it down and put it into my bag, as per usual. That evening, I found the fan whirring strongly and the body heated up. Immediately I shut it down and then tried to turn it back on. Alas, it didn’t turn on.
I put it on the charger and did an SMC reset. The charger light blinked momentarily from orange to green. At this time, the unit has a more normal temperature (slightly warm, but not hot). Still it doesn’t turn on.
Based on a suggestion “on the web”, I’ve hold the power button for 10 seconds, Released it, pulled out the power plug, hold the power button, and while keeping the power button held down, I’ve put the plug back in and waited for another 10+ seconds (probably about 12 seconds actual). Still it didn’t turn on. I’ve pressed the power button again, still won’t turn on.
Then I placed the unit in my bag.
Strangely the unit seems to warm my bag. Indeed, after about half an hour, it became hot again even when the screen off and no apparent activity on keyboard backlight as well. I had to take it out from my bag every now and then to prevent it from overheating (again).
Back home, I’ve charged it again. It seems to be charging. SMC reset seems to respond. However no screen nor backlight, not even the chime.
What can I do to revive it? Logic board replacement seems very costly and probably not worth while if I’m just looking to resale it at this point of time. However I’ve asked around and shops only offers $50 for a dead unit.
