There doesn't seem to be a solid solution for this issue. Judging from the amount of heat on the connection where the light is and the higher watt adapter needed for this particular model, it seems the problem is the power demands of the battery and the power demands of running the computer can exceed the power supply and this causes the battery, connections and related circuits and chips to heat up and not charge properly a spread of problems culminate and the charging system goes into a non-responsive mode and the computer blacks out for 45 minutes to an hour and a half. It is as if the heat is a major factor on draining the battery and preventing it from charging, as if it causes some kind of short. When it runs into the no charge problem, the battery drains extremely fast, much faster than if you are just using the computer unplugged on battery life, which can be as much as 70 minutes on a good day. Right now it is at 39 %, was at zero 15 minutes ago. Once it starts charging, it charges quickly. The computer just will not respond, no matter what you do, for a couple of hours and then, after you keep trying better connections, restarting and many other things that may be having no effect at all, the charging cycle kicks in. Letting everything cool down seems to help most of the time. Sometimes shutting everything down to let it start charging will get it charging, sometimes not. After a thorough cleaning of the connections and making sure the little pins inside of the mag connection extend outward, sometimes banging the cord with the pins facing down on the counter when it is wet with alcohol, then checking with a magnifier glass to see if the contact pins extend out instead of being recessed inward, and carefully connecting making sure the cord is flat, the pressing the cord in and taping it tight so the connection doesn't shift. The routine for me is cleaning the mag safe connecter with alcohol (with the cord unplugged) and the end of the cord itself using a swab with some of the cotton peeled off. Went for hours today trying all the tricks but it would never start to charge, always remained 0 %, the amber light on so showing that it is charging and then the screen blacks out because the charge fails to start. The mag cord connection with the light becomes very hot when it is charging or trying to charge. It is as if the power demands of this computer exceed its ability to recharge and that constant drain combined with the battery being charged yet over-drained at the same time just causes havoc and the battery to become unresponsive for a long long time to allow things to cool down. In such cases, iPad will display an alert: “Charging is not supported with this accessory," the company explains.Having the same problem for a long time. “iPad does not charge when connected to an older accessory that only supports FireWire charging,” Apple outlines. Users must also ensure the computer used to charge the iPad is plugged into power and not in standby, sleep, or hibernation mode. “If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.” “Make sure your computer is on while charging iPad via USB,” reads the tip.

“When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode,” says Apple. The Mac maker assures customers that the iPad will also charge when attached to a computer with a high-power USB port (many recent Mac computers), and even with an iPhone Power Adapter, although more slowly.

Over at the Support section of Apple’s website, a few charging tips are dished out for owners of an iPad.Īpple stresses that the fastest way to charge your tablet PC is with the included 10W USB Power Adapter. Sucking juice from the USB port of your new-generation MacBook Pro will result in less work done with the notebook, but it is reassuring to know that you can charge your iPad any time, any place, in case of an emergency, if you’re not carrying the tablet’s adapter with you. The new range of notebooks show 500mA as available with an additional 1600mA, which combine to make 2100mA of power - almost the same as the power adapter of the iPad. Tests carried out on Apple’s newest breed of MacBook Pro computers have revealed that they can charge an iPad about as fast as the tablet’s own wall charger, whereas older systems take longer to replenish its battery, or don’t charge it at all.Īccording to a post by 9to5mac, the previous generation of MacBook Pro laptops shows 500mA as available with another 500mA “Extra Operating Current”.
