Blinking amber light on charger...

Had the blinking light on my charger that I’ve seen several other mac owners went through. My situation is I have to keep disconnecting my battery to get it to come back on. It’s happening maybe 1-2 times every couple of weeks. Today I had to do it twice in a matter of a like 5 minutes. Would this obviously be a “faulty battery &/or charger” or is there potential for something more serious going on here? Grant it, every time I go through the process, the computer powers up, whatever charge I had before it went down, it goes right back to that same charge, and everything works fine. However, sometimes I can charge it to 100%, shut it down, or put it in sleep mode, & it will go to the blinking light whenever I try to resume use. What else could this be besides a bad charger or battery, or both?

Says the battery is good, so what could keep causing me to have to unplug the battery over and over.

Try these resets:

SMC

Shift+Control+Option+Pwr press all 4, release, power up. 


PRAM

You reset the PRAM by rebooting a Mac and then immediately hold down the right Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won’t work.

Blinking Amber MagSafe light usually means Bad Battery or Wrong Charger.

=== Update (11/9/2020) ===

Check the wattage of the charger, the device requires a certain wattage, chargers look very alike but you don’t want to power up a 90 watt device with a 70 watt charger, not very long anyway.

You have Volts, Amps and Watts check the chargers wattage.
