Light on power cord magsafe 3 started blinking and then just stopped. I am not sure if I need to change the cord or if it is the power port on computer. I am now using an usb c to power and it is fine.

We have Apple Diagnostics: Use Apple Diagnostics to test your Mac - Apple Support, but it is of limited benefit. All it is really capable of doing is identifying the presence of operable hardware. On the other hand if it positively identifies a specific fault, it is certain to exist.
A more practicable solution is to substitute a known working MagSafe cable: USB-C to MagSafe 3 Cable (2 m) - Silver - Apple. If it doesn't work either, then it's likely the power port is in need of attention.
It's not a bad idea to have a spare cable on hand anyway.

The usual method is a visual inspection.
Read If the indicator light flashes in If your MagSafe cable or power adapter isn't working - Apple Support. At one time Apple included some helpful photographs but for some reason they omitted them in that more recent document in favor of a very generic "Use a dry cloth to wipe the MagSafe 3 port and MagSafe 3 connector. Make sure both the port and connector are dry and clear of any debris."
I suggest careful cleaning using a clean, dry, soft cloth or bristle brush. Do not use solvents or anything else that might exacerbate the problem.
Thanks John, did all that still nothing. Is there somewhere to check if all ports are working? I remember years ago on a window based computer there was but can't find it on mac. Reason before I buy a new cord I wanted to check if it is the cord or not. Thanks for your help in this matter. Stay safe and connected.
Thanks John. I took it to the apple store here in Cyprus and they checked the cord, found it not to be working so I just bought another one. Strange they said my comp was bought in Nov of 2022. Not usual cords stop working just like that. Wonder if anyone else had this problem with the macbook air m2 2022?
how to check if it is the power cord or the power port when it is not working
