my magsafe thing doesnt work and i need to replace it. please add links if you know of a good power adapter

Here’s the part to fix it: MacBook Unibody (A1342) MagSafe DC-In Board Or a cheaper one on eBay: http://www.ebay.com/itm/MacBook-13-A1342… And the guide to replace it: MacBook Unibody Model A1342 MagSafe Board Replacement Also a charger if you need one: http://www.ebay.com/itm/Genuine-Apple-Ma

For 30$/euros you can get a good second hand charger from Craiglist/Leboncoin/ebay. Don’t use chinese chargers even if they cost 30$ new
