I used 65w as I didnt have original 85W, I figured if Voltage is the same it should be okay for diagnostic purpose. Obviously I was wrong. With non original 85 charger I get fan spinning as soon as I plug it in and PM_SLP_S4_I 3.3v. Thank you Duke. Last quick question, shouldn't it chime after...

Tell me, without screen, and idol state (not on) is there current consumtion if you connect power supply to battery terminal on the board? After that push power button, does it start from 0.05-0.2A, or from 0.20+A?

That is correct, Thanks for details.

I will share what looks like not popular opinion, REPAIR IPHONES ARE TOTALY WORTH IT. Remember despite what every one tells you, you dont have to charge $20 for repair AND you DONT have to use cheap screens. You can buy original screens and charge $40-50 for repair(parts+$40-50). However that...

I have mac mini 820-2993 there are no schematics available, the board is in short. Power supply works. I inspected board carefully and didnt find any bad capacitor or other deformation. Board is not water damaged. Well at this point I tried simply supply power to the board directly in hopes...

When I plug in charger laptop chime even tho lid is closed. I open it and it is on login screen. If I shut it down with charger plugged in than fan will stop. If I unplug charger and put it back fan start spring again...

turns on by itself if plug in charger It turns despite the fact that lid is closed, I can tell that LCD is on, that's why I think it is not normal. Now It charges normal 35% in about 40 min.

Thank you, for the explanation. I live in small town, nowhere to get battery, I wil order one online. will try new battery just not sure if that will help. My battery is not dead, it chargers and holds charger just fine now. Well I will try anyway if there is no other tips.

If you are talking about iPhone 6 and 6+, they have typical issue of 2 pins coming off in the conner on baseband chip. That causing iPhone to see IMEI but says searching. So reflow is only temporary fix, reball is the way to go, you will have to make 2 jumpers. Also if it is iPhone 5s,5c it...

Hi everyone. My first question is, whether it is normal for macbook pro 820-3115 to turn on by it self when plug in charger while device is off. I am asking because I saw one of louis's videos where he said some macbook air would do that... I have a customer macbook 820-3115 that came as "not...
