My daughter came home from school where her Macbook Air had been working fine. Not sure if it ran out of charge or she powered off. Have plugged it into the charger and there’s nothing going on. Can’t turn on the laptop. The charge light doesn’t come on to the magsafe adapter charger. Have tried another charger that works and still nothing. It had the logic board replace by Apple about 18 months ago, so I presume that’s OK but couldn’t say for certain. Anything else I could try?
You may need a new charger. Try cleaning the MagSafe connectors following this Apple T/N: Apple Portables: Troubleshooting MagSafe adapters
