I had a similar thing happen to my old Macbook. I discharged the battery all the way down and then couldn't recharge it for about two days. When I finally could charge it, it wouldn't charge or turn on. It turned out to be the battery. You can probably get a replacement battery from Apple (if it turns out to be the battery), but I found cheaper options on ...

Your charger is not the issue as evidenced by your testing it on other MacBook Airs I've tested the charger with multiple other MacBook Airs, and the charger works fine. You have a problem with either your logic board and/or your DC Power I/O Board. You need to take it in for service.

If you can at least start the Mac up and make the battery lights flash, it's lint. Here's how you clean lint from a port: Get a toothpick. Stick it in the port. Carefully rub the inside of the port. Pull out the toothpick. Repeat.

Apple makes 3 different chargers for their MacBooks that you need to be concerned about: 45-Watt -- For MacBook Airs. 60-Watt -- For 13" MacBook Pros. 85-Watt -- For 15" and 17" MacBook Pros. You can use a higher-wattage charger than you MacBook requires, but not a lower-wattage one. Yours was an 85-watt charger. If your friend's charger was a 60-watt, ...

Not all of the listed items have a voltage of 12 V. E.g the HDD+ODD has only 5 V and the CPUs have a much lower voltage. According to Intel the voltage of the Xeon® Processor X5670 maxes out at 1.350 V and the TDP is 2 x 95 W (and not 2 x 12 V x ~46 A = 1104 W). So just adding all currents and multiplying them with 12 to get the wattage is not appropriate ...

Not sure what is going on, but, I've found that even though the machine looks like it is shutdown, I have to hold the power-button for 10 secs for force turn it off. After I've done that it starts up fine.

Yes - you should be fine. The Apple TV runs iOS which has several technologies to help maintain system reliability when it shuts off abruptly. Apps are sandboxed and easily deleted and re-installed from the App Store if they should get corrupted data or settings. The OS is easily wiped and restored from the network. Changes and writes to storage are low ...

One option is to increase the niceness of the main CPU consuming processes. You can find these processes in the Activity Monitor or in the Terminal with this command: top -u If you find out that a process with pid P is the most CPU consuming one, then you can increase the niceness of that with this command in the Terminal: sudo renice -n +10 P

This has been happening to me for over a year.. I wrapped my special cord in electric tape because it was falling apart. I have no idea why that's the only cord that will charge my phone. We have 4 extra lightning cables from apple and none of them work with my phone but they all work perfectly with my husband's. My special cable can charge his phone as ...

Voltage fluctuations are normal. I am assuming you are in the UK or Europe. If so, your voltage should be between 220V and 240V so everything is within range. Besides, the UPS is designed to "smooth out" these voltage fluctuations so your power is clean coming into your Mac. What is key to finding out what your issue is what the shutdown code is in your ...

Yes, at least for the iPhone 6S using the Apple USB-C to Lighning 2m cable. I just started using it this week with mine and haven't had any issues. For a few years I've charged my iPhone with an iPad charger. Not sure if the 29W charger is faster, but at least it seems just as fast. Also, I heard in a podcast about videos warning about USB-C to USB ...

Charge Cycle means nothing, assume you plugged in all the time for 5 or 6 years, the cycle is still 0 but does it mean your battery is 100% health? No. You should search for your macbook model to find out what is the design capacity of your macbook, and divided by your current max full charge capacity to find out the health of the battery. Or you may ...

You haven't mentioned what's the model of the Mac you are using, Apple's Determining battery cycle count for Mac notebooks will tell you more about the Charge Cycle. Also in case you are still in warranty, which I assume you are not cause of so many charge cycles, you can go to the Apple Store and get the battery diagnosed, if they find a problem they will ...
