MBP won't boot no matter what

I have a early 2011 13” MBP with 2.3ghz i5. Been looking around this forum for a month, tried every solution I could, but it just won't boot up.

Below are the list of things I have tried:

  • Replaced battery
  • Replaced MagSafe DC-In port
  • Resetting SMC
  • Resetting PRAM/NVRAM
  • Used another 60W MagSafe adapter
  • Replaced RAM
  • Replaced HDD

Edit: I plugged it in for hours with orange led indicator and it seem to be able to charge my battery again, but still no response.

When I press the power button, there's no response, no Sleep Indicator Light (SIL), nothing runs.

However there seem to have a weird response on the screen. When I press power on, there's no backlight, but the screen will turn slightly black if you stare closely, hardly noticable.

Has anyone got any idea what is happening to my macbook? Thanks.

Did you have a liquid spill or sit your system down on a wet surface at some point?

Nope. No water damage at all.

Sorry to say your processor has died.

If your system has gotten wet I could have seen cleaning the logic board might have fixed things.

Here’s the IFIXIT guide you’ll need to follow: MacBook Pro 13" Unibody Early 2011 Logic Board Replacement within the guide is a listing of possible logic boards.
