Try resetting SMC and PRAM, that’s about all you can do. CPU should be alive if mouse is powered on. If you do get back the boot chime but screen stays black try plugging your Mac to a screen/TV to see if you have an image there. If you have no boot chime even after resetting PRAM there’s a serious issue at board level to deal with, but that needs more indepth troubleshooting that requires tools and skills. However, it doesn’t seem to be a power issue.

nop sometimes when i reset smc with the instruction that has pusingthe power button for 15 sec the fan powers in high revs do you think is a ppbus problem?

@carlos_15 The 10" power button pressing followed by plugging in Magsafe is a SMC bypass, the reset is done by pressing left shift+ctrl+alt+power button for 1". If it starts with first method and full speed fans there's a SMC issue.
