Macbook pro won't turn on My 2008 macbook pro won't turn on.

I replaced the battery less than six months ago, but it seems that it died again.

The charger is connected and it shows a green light, but the battery's lights don't turn on. When the battery button is pressed, only the first light blinks.

I tried resetting the SMC multiple times, but no luck.

Any ideas?
Verify that you're using an 85W Apple MagSafe adapter, the 60W will not provide enough power to turn the MacBook Pro on.  Try with a known-good 85W MagSafe adapter, if that doesn't work, you'll need to take it into an Apple Authorised Service Provider (AASP) or the Genius Bar.

Good Luck!
