I have this macbook and it takes in 20v, .98a, and 18.28w. it clicks but doesnt power on and the touch bar doesnt come on either. ive tried a PRAM reset to no avail. any ideas? i was watching it and it jumped too 3a and 30w but then went back down.
Hey John, That is quite unfortunate and sounds like a power delivery issue. My friend daily’s a 2019 MacBook air and his has the same issue where it clicks but is stone cold. This has caused him lots of hassle and after a Logic board “Replacement/repair” it happened again and he has to do more troubleshooting. As far as external factors, what charging brick are you using? 30W/3A = 10V. If that is the case you are most certainly using the wrong charger. The macbook pro uses a 61W charger. At 3A 10V, Your using a macbook air charger which is half the needed power. I did a quick calculation and it would appear that (For my lenovo type c charger rated at 65W), it is going at 20V 3.25A which is enough for it. If i look at my magsafe 2 2015 macbook pro, it is 16.5V 3.65A which totals to 60W over magsafe. One last thing, if we take a look at Apple’s official page for this product it shows a 61W charger (IDK the specs of). In short then, it may be a good idea to get a beefier charger. If that doesn’t fix it let me know and I’ll do some more research. Update: 17/04/22 10:54 AM AEST: Apple configurator 2
