If a portable computer, such as a MacBook, quits when disconnected from outlet power, it probably has a battery problem. Take it to a service provider if you can not determine if the battery is dead yourself.

The computer will only consume what power it needs. No diffference. if you have a 350watt power supply, and it is using more then 70% power consuption, the life of that power supply will be short, so always aim big when picking out a power supply, ie: 50-100 watts more than what you would actually need.
