Hi Everyone, I have a MacBook Air 13 ’’ Model A1466 EMC2925 It does not turn on, and when charging, the MagSafe stays at orange. I have left it over a day now, and nothing. I suspect the issue is the battery, but I’m not totally sure. Is there a way to prove it? Best,
I have the exact same issue on a client’s Macbook Air (13" 2015) : the charger goes orange even when the battery is disconnected. The first time she brought it to me, the battery was fully discharged (after several weeks unplugged) and the macbook worked fine, but after one day or proper operations, the issue went back : impossible to turn it on. The Apple Store told her that the motherboard needed a replacement (a 600€ repair). I’m wondering if a replacement of the left IO board would solve this issue Update (08/25/2020) At the end, I didn’t post the final result : it was an oxidation issue with a faulty charging IC, I found someone in my area who changed it for far cheaper than the Apple store
Probably a board issue. If I had to guess i’d probably say corrosion on C1910 or in the u1900 area. Really common on MacBook Air’s from the humidity in the air. I’m guessing this isn’t liquid damaged?
You’ll need to disconnect the battery and then plug in the MagSafe charger at that point the system should startup on its own. Here’s the IFIXIT guide to pop the bottom cover and disconnect the battery: MacBook Air 13" Early 2015 Battery Replacement follow the steps to Step3 Tell us what happens at that point.
Hi, I had a similar problem and after visiting the Apple Store, talking to various repairers without progress I concluded it was the power supply or connection. I used some blu-tack to clean the small connector points on both male and female of the Magsafe / MBA and that fixed it. Seems the problem (for me) was just dirt & dust on the connection points that seemed to allow a connection, but not enough to power up or charge. Hope it works for you.
Had exact same issue, MBA (early 2015, A1466) does not switch on at all & charging light on the magsafe cable remains orange. After trying everything including remove battery etc tried switching it on after removing the Trackbad/Keyboard cable (from any one side, either from the logic/mother board or from the trackpad side. MBA boots up fine now and battery etc everything shows ok in about screen. FYI, it also boots up fine with external keyboard mouse connected over USB or bluetooth. Probably need to replace either the keyboard or the touchpad ? (Though its strange that even fan wont turn on if kbd cable is attached) Any way to know which one to replace - kbd or touchpad ? The keyboard cable connects to touchpad which in turn connects to the main board so i can eliminate them by connecting one by one. Or maybe just the touchpad cable ? The moment i insert it into the zif connector system shuts off at once. It seems instead of replacing keyboard its better to replace keyboard+top-cover; Is that correct ?
I had a similar issue but it was an A1465 MBA, that would not boot so I did some YouTube research and it pointed to the I/O board being defective. So I removed the connectors, and battery (of course, the first step), no damage so I proceeded to the reassembly process. Reconnected everything and would not boot, removed the battery and ran it on AC power it would boot. Then I let it charge completely and powered on fine, ran the Coconut utility and that showed perfect health except the cycle count was 859, Shutdown the machine and put it all together, it was dead. Re-opened the laptop, disconnected the battery, and ran on AC Power, everything works beautifully. Just to validate my testing process, I reconnected the battery and AC Power, (Dead), removed the battery, and boots up fine every time. The Battery was the culprit although Apple System Report showed Normal conditions along with Coconut. Always keep spare batteries on hand - Lesson learned. Sorry for the long message.
