My 2015 MacBook Air won’t turn on

My 2015 MacBook Air wasn’t turning on and I went through the suggestion to reset the NVRAM. It worked for a few weeks, although with some glitches. Now it’s not turning on at all despite trying resetting the NVRAM???

Power cord shows it’s fully charged (green light is on when connected) but nothing is working to power it on!

Any help/suggestions are appreciated!
