Ok, I solved the problem. The computer socket where the charger was going in had some pencil marks in it. My friend just used a pencil eraser inside it, and then blew out the rubber, and it works like new.

Do you have another charger? If yes and if that works, maybe your first charger was damaged. Maybe there's a wire inside of it has broken or something, or the charger became loose (in wires or plug). But if you tried another charger and nothing happened, maybe the problem is in you laptop.

See this question for more info. In short, you're taking your device's life in your hands when you don't use legit products. You have a multi-hundred-dollar device, do not cheap out on the thing that's directing nontrivial amounts of electricity into it! Authorized products aren't that expensive and you can be sure that you won't have strange things happen. ...

Check to make sure there's not any lint buildup in the Lightning port. Get a wooden or plastic toothpick (do not use anything metallic) and clean the port out, swiping from one edge to the other, then pulling out any bunched up lint or dust. Even a small amount of buildup will prevent the accessory from fully seating properly, sometimes generating a "This ...

So iPhone 5s use a Lightning cable rather than the old school dock connector. Lightning cables actually have an authentication chip in them, hence the message. There's a jailbreak tweak out there that may be worth checking out, but it's quite old and may not have been updated. Your best bet would be to just get a new cable. Certified cables can be had ...

Unless there is a problem with the battery itself you can likely use your Mac (laptop, I presume) indefinately. I have seen that done at a number of places with Macs and PCs used as a "spare" computer. I will usually remove the battery from the laptop (if possible) to avoid the battery causing any damage to the computer, but depending on the Mac that may ...

iOS does not store that information anywhere. The capacity of a Lithium-Ion battery is simply based on the Voltage that the battery is currently outputting. Take a look at a Voltage over time chart for Li-Ion batteries. More information about determining capacities for Li-Ion batteries can be found here.

If you are carrying the Macbook from outside (cold) to inside (warm & humid), you may want to consider bagging the Macbook in a sealed plastic bag (Ziplock or similar), so the condensate will form on outside of the bag, not the Macbook. If the Macbook is in a case, a bag, or sleeve, the case should supply some insulation to shield the Macbook from the ...

From Apple Support: Find the right power adapter and cord for your Mac notebook Power adapters for Apple notebooks are available in 29W, 45W, 60W, and 85W varieties. You should use the appropriate wattage power adapter for your Apple notebook. You can use a compatible higher wattage adapter without issue, but it won't make your computer charge ...

It will be fine. The MacBook Pro will charge with the Air's charger well; it will just be slower than if it was on its original charger. One can even charge a MacBook Air with the charger for the MacBook Pro, if one wanted to. I have attempted this myself and have had no problems.

Usually (depending on MBP model) - there is only one fully powered / full speed bus. You could try resetting the PRAM / NVRAM. https://support.apple.com/en-us/HT204063 Here is a good support article on USB ports and their corresponding power. https://support.apple.com/en-us/HT204377 From my experience iPads can request a lot of power from a standard ...

The price difference between Apple's 85W and 45W power adapters has always been very small, which one could assume means that they probably use the same high quality components (wiring and connector) for both, with the only difference being the size and output of the adapter. This also makes sense from a manufacturing perspective, but naturally we will never ...

This happens to me too. I clean the connectors, especially the area around the pins on the computer case. This is a very small area; last time I used a heavy paper stock card and cleaned out any dust or debris that might have been there. Problem solved! This has happened to my computer a few times and the solution is always getting either the power ...

Constant charging should not damage the battery in an extreme manner. Yes, you would get more life from it if you would let it always cycle between 40 and 80%, but the Mac is already cycling power in the high 90s even though it is not showing it to you. I have not been cautious at all with by 2009 Macbook Pro and I can still get around 2 hours of autonomy ...
