Macbook AIR A1466 turns off intermittently (820-00165A)

[GadgetsFixLeeds]

I have changed the battery, it stays on for a while longer now but still just blacks out/Turns Off randomly, can anyone help?

First of all, welcome to the forum!

Any history fault available?
Inspect board for corrosion.
Start in SMC bypass and see if still turns off in the same manner.

Hi, thank you
the board is clean, there's no corrosion at all. I still cleaned every component.
I am sorry but what does SMC bypass mean?
like how do I bypass it?

We have a lot of basic information on the forum.

HOW TO collection

I hope this "How to" collection will help our members. I will possibly modify this post in time, if updates available. Trigger SMC_ONOFF_L (PMU_ONOFF_L): It reffers to simulate power button function, when the keyboard is not connected. We need to do this when we work with the board...

Many times can solve a problem just searching and reading more threads possible.

Don't forget to test with original Magsafe 2 charger; other than the actual used.
