Hi Guys! I have a problem with a Macbook Air 11" late 2010 Problem: doesn’t boot led on magsafe connector doesn’t light up. This is the second time this happens, last time I left it on the charger for over an hour and suddenly the led was lighting up and it was working. MacOS showed the battery condition was Normal. It was fully charged yesterday and hasn't been used. I think the charger is ok. It was working yesterday. I tried a SMC reset, no response. I think it’s a battery problem? All help is welcome. Thanks!
