MacBook Pro won't turn on at all.

MacBook Pro won't turn on.

Capacitor 68C25 became very hot when MagSafe adaptor is in power outlet.

See picture.

Only 6 of the 8 LEDs light up when MagSafe adaptor is in power outlet.

No LEDs light up when MagSafe is out of power outlet.

MagSafe power adaptor has been test and find to be oke.

SMC-test has been performed, but still won't turn on.

A lot of key-combination test has been performed, but still won't turn on.

(Option-Command-R-P) has also been performed.

There is absolute no noise coming from the computer.

No video output.

No Screen display.

The computer is totally dead.

Looks like the battery is not charging, maiby a deadly battery.

Computer does not turn on with MagSafe adaptor or without MagSafe adaptor (battery).

I just make my second order for the 54 piece tool kit.

Do you have or know where I can get the capacitor 68C25. See picture.

Hope you can help me fixing my MacBook Pro.

You may have already done this, but have you reset the PRAM/NVRAM multiple times? Hold down Option+Command+P+R until you hear the startup chime three times. Is your display even powering on? Look carefully. Is there any backlight bleed through the screen?
