macbook suddenly shuts off and doesn't power on again

[heathercarey]

I've had my macbook for about 15 months. i noticed a while ago it had trouble turning off completely when running only on the battery. then a few weeks ago it shut itself off and wouldn't start up again. the power cord indicator was orange, but nothing worked. ordered a new battery, that didn't help. tried a different power cord - nada. i took it in to an apple repair shop and they said something about the internal power connector (i'm not a techy) and took 2 weeks to repair. i've had it back 3 weeks now and the same thing has happened. only this time there is no indicator light on any of the power adapters. and my partially charged batteries do not work on their own either.
any ideas? i don't want to keep fixing the same thing and every few weeks it keeps breaking again. i mean, what's the point in having the computer then, right??

I highly recommend you bring this in again. It shouldn't cost you anything;

A replacement product/part assumes the remaining warranty of the original product or ninety (90) days from the date of replacement or repair, whichever provides longer coverage for you.
