MacBookPro does not power up on AC power or battery.

MacBookPro does not power up on AC power or battery. I've noticed a number of "My Macbook Pro won't turn on" posts here, but my symptoms seem to be different (read: worse) than the other posts that I've read, such as this MacBook Pro no startup sound, and not able to start.

"reset the SMC works but you need to follow this and to do all the steps in the way i describe (for macbook pro with removable battery):

1 - Remove the battery with magsafe connected

2 - Remove Magsafe

3 - Hold start button for at least 5 seconds

4 - plugged Magsafe connector

5 - plugged the battery

The light change green to red. Wait 10 minutes and the computer start !

See ya"

The very first thing I would do is to reseat the Uppercase cable to the logic board as your machine does not seem to be getting a start signal. Check your battery for swelling. Do your restarts without the battery in. MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Upper Case Cable Replacement
