When I plug my razer blade 15 (2021) it has very recently started either not charging, or alternating between battery and charging. It has become mostly unusable for the purpose it was bought. I have tried replacing the power supply but to the same effect. I plug it in and it shows charging for anywhere from a second to less than a minute then just seems to revert back to battery.

Things I’ve tried:

cleaning out the port on the computer

buying a new charging cable

installing latest drivers/versions for everything

turning off and on

This is a recent occurance.

Any ideas?

Thank you!
