Nasir bhai is one of those few talented engineers who can bring new life to any dead motherboard. Apple devices are one of the most difficult to repair but you can see in this video how methodically the problem was diagnosed and fixed.

I always view you one the best engineers of laptop in Nehru Place Delhi, I really feel proud of you that you are my younger brother. Have the same confidence, you have made many people a skilled person. I have also started learning a bit now. Thanks for you beautiful video. You are master in tracing problem with resistance. God bless you. Keep sharing your experience with the world who are interested in this field.

Thx for sharing this. I'm having exactly the same pb with my MacBook Air 11 inch. What's the key component you've just fixed on the motherboard that solve the pb?

Dear thanks for your contribution, I have the same problem in the same model, but when checking the resistance is its value correct, what other component can cause this failure?

THANKS FOR THE GREATE VIDEO .. I HAVE A A1286 PCB THAT ALMOST SHOWS SIMILER CASE .. MY PCB HAS A GREEN LIGHT WHN I CONNECT CHARGER TO THE FAN STARTS UP FOR 10 SECONDS AND THEN POWERS OFF AND AGAIN STARTS UP AND THE FANS ARE AT FULL SPEED AND IT STAYS ON ONE WAY, TILL I DISCONNECT THE POWER CABLE ….AND THERE IS NO DISPLAY OR CHARM NOISE WHEN IT TRYS TO BOOT OR FAN STARTS, THIS IS WIERED PLEASE ANY ADVICE WILL HELP I AM A …...NOOB THIS IS MY FIRST APPLE LAPTOP .THANKS

Thank you! I solved my 820-2936-B problem

thanks to share valuable information keep on continue.

SETH I'm having same problem, my mac was working perfectly and I left it to go out coming back everything was blank. If I plugged in charger charging light will come up also battery status light by the side will give me battery status, but it will never power on, can this be battery aswell? Because condition before was change soon. I remove the battery and plugged in charger to power it on also no power. Can I get new battery and try it or the problem is what you just fixed now?

I got an A1342 that comes on with no display and solid sleep light. Fan spins and after maybe 10 seconds, it speeds up and power is cut. It will then reboot on its own and this time the fan will speed up again. Only this time, the machine will not power off. It will stay on with no display, sleep light lit and fan on max speed. This is when plugged into MagSafe charger. First power up always causes a reboot and the second time it stays on with the same symptoms. If I do the same with just the battery, it will do the same, but continuously reboot just as the fan speeds up. Under battery, it cannot stay on. Any idea what might be the cause here?

only with the replacement of R7005 worked?, because later on the video i didnt see the apple icon on the screen and didnt heard the boot sound, i am not sure if it worked.

Hi Nasir I have the same problem with a MacBook Pro A1286 late 2011 ? I think it is a current sense problem ? Can you help me or can I give you more information about the measures that I have done ? Thanks

You did a great job but you didn't zoom in for us to see what you changed

Sir I have same MacBook Pro A 1278 problem is that it’s working very slow all the application and function are working very slow please help

could you help me find where can I get like this MacBook Pro schemes ? thank you

Hello Nasir, Im trying to locate the resistor but couldnt find can you kindly share the picture of it location on A1278 mid 2010 board

I have same issue in 2011 Early MBP. Is there anyone you recommend for service in chennai ?

I'm completely faced with this defect and I haven't been able to resolve it. It doesn't have 5V or 1.35V... They keep varying, the cooler rotates and stops... Could you give tips on which vital points to resolve, I'd appreciate it... There's no need to enable the TPS51125, injecting 4.20V into the line 5V TPS51125 heats up but it's not, I already changed it, the same thing continued.

Exactly my board. Screen not working, not booting.

Which resistor u changed i didn't see it can u upload a pic of it

very nice

thank you sir i have don
