MAC screen freezes onlywhen lightning and power are connected together

I have noticed an issue with my 13” MacBook Air, the screen would freeze and then would have to hard reboot the device to clear.

The problem occurs only when Thunder port (for HDMI connected external display) and power are connected simultaneously. If I unplug any of these, the problem is never seen, The systems OS is up to date.

Any pointers here would be appreciated!

Also, the same connector when used on another Macbook Air same as mine, does not create any problem.

I suspect you have a AC outlet power issue or you have a fake MAgSafe charger which is mis-wired internally.

Get an AC outlet checker like this one AC Outlet Receptacle Tester 110V to check the outlets wiring.

I strongly recommend you use a good surge protecter or better yet a UPS making sure all of your peripherals are also using these outlets.

As far as your MagSafe unit: Do make sure you have a real Apple unit! Here’s more on the risks:

Even getting your power issues resolved you may still have a problem as the MacBook Air’s logic board could be damaged.

Think the charger shouldnt be a problem since this is the original charger that I have been using. The problem has been observed only during last 7-8 months only.

Also, I have been using the same lightning connector also (although) that is not the apple genuine connector.

Currently using 1 similar to this

it's a 3 in 1 connector. Could this be a problem?

FYI: The port you are using to connect your external display is a Thunderbolt port not lightning port. The Lightning port is what is on your iPhone or iPad.

Yes, you really can't use these splitter devices. There are a lot of odd devices like these which people sell which is not well designed.

The original Thunderbolt interface was not designed with the needed power for a true hub. If you look you'll find the major makers of multi-port hubs required an external power transformer to work.

The newer Thunderbolt3 which uses a similar connector to USB-C and also offers USB-C compatibility this interface offers the needed power so small hubs can be supported.
