Figured it out. Opened up the laptop, and a wire was lose right by the fan. That seemed to be the charging issue. Another wire was lose on the other side, may have been audio. Everything works great now! Prob bumped the air a little too harshly.
In general, it isn't a good idea to put a power adapter on a light dimmer as the circuitry could malfunction if the voltage is too low. That being said, I believe the 45W adapter for the MacBook Air will survive- it just won't charge if the dimmer reduces the voltage below 100 volts. The AC is converted into DC and then applied to a voltage regulator ...
I make no guarantees here. Probably no harm will come to the MBA. The power is buffered through the transformer in the power adapter. You might burn out your power adapter if you vary (dim) the voltage while it is in operation. I would also strongly suggest not plugging in the power supply to the adapter until you have adjusted the adapter to full ...
Take a look at the output of pmset -g assertions. This shows things which are asserting "don't sleep, don't shut down" sorts of events. I'm having the same problem, with these outputs: 2014-12-09 20:14:39 -0800 Assertion status system-wide: BackgroundTask 0 ApplePushServiceTask 0 UserIsActive 1 ...
There is no safety difference whatsoever. The 3 pin grounded cable goes to a 2 pin connector which then plugs into the adapter. This means that the grounding is not even connected so there is absolutely no difference safety-wise. Main reason is for those places where you have to rotate the wall plug to insert, or you need to insert a grounding pin in to ...
Months late on this one - but there is no point in grounding a double-insulated device, such as a power-supply. There is no earth circuitry inside it anyway. If you ever see a similar device with an actual cable leading into it, you'll notice it runs on only 2-core wire. UK adapters always have the 3rd pin, but that is simply because the pin is needed to ...
The Apple Store has more information on the USB Power Adapter. It says it is compatible with all iPhone models, from the original iPhone all the way through the iPhone 6 Plus.
I also have a 13.3 MacBook Air Mid-2013 with liquid damage. I replaced the keyboard and the power button still doesn't work. So here is how I get it to boot up: Disconnect the battery for a few seconds (charger not connected) and then reconnect the battery. Connect the charger and after a second the MacBook will boot up. I just let it to go to sleep when ...
yes, they are both 5w chargers.
