[QUOTE="krs, post: 1816098, member: 67742"] I have had my share of Mac laptop chargers fail over the years and not just the cable problem at the magsafe end that is being described here. Some chargers just "died" for no apparent reason. Trying to fix the charger is pretty near impossible, for one the case is sealed and has to be cut open, and a genuine Apple charger is really packed full of components compared to a third-party charger. In general I found that Apple-branded chargers are not any more reliable than third-party chargers, but I prefer Apple-branded ones, even used ones on ebay, because of the control built into the power system that delays the power connection when you plug in the magsafe connector. One can tell byobserving the LED on the magsafe connector, on the Apple-branded one the LED will only light up after a second or so after plugging the magsafe in, on the third-party ones there is no power delay control and the LED comes on immediately - on some the LED stays on even after one disconnects the magsafe. I have never come a cross a third-party charger that has incorporated the power delay feature - if anybody has come across one I would sure like to know. My comment re Alaska21's question about buying a spare would be - it depends. If you are close to an Apple store and don't mind paying their price for the power adapter, you could just wait to see if you have a problem and if so, then get a replacement. Some adapters I had have worked for years. But if an Apple store (or dealer) is not readily accessible, I would definitely get a spare if you can't live without your Mac for a few days. Remember, once the power adapter fails, the operating time of your MacBook is limited. [/QUOTE]
