PMU Reset ?

I bought a new Battery and Did the Logic Board Reset. Still no change. Not sure what to do next. I have searched and I see a lot of people have had a similar problem. But, no real solution it seems. Maybe I'm wrong. Any ideas welcome.

Okay. Sorry for that. I just was hoping someone knew more about the PMU Reset and how critical it was if pushed multiple times. Thx

Oh Boy. Which I would assume is more expensive than the worth of the computer? I don't mind spending the money to get it replaced if it is money wisely spent. Thx

Ok. Thanks. I was thinking of taking it to my Apple Store near me. It would get diagnosed correctly and warranted on whatever is repaired. But, my concern was if it was worth going to all this trouble and expense. It has been a great computer and aside from this, has been trouble free.

Well, I got it to Start after sitting with the new Battery in it and hooked to AC. I let it "Run" for about 3 Hours. "Restarted" it and now it won't Start-Up again. Weird. Just the White Light Blinks when pressing the Power Button, like before. Any ideas?

Thx

Update: It Started-Up again. It seems if I let it sit for a few minutes I can start it. I hate to shut it down or Restart. What to do?

Thx

Okay. I'm able to start it in Safe Mode or by normal Start. However, I'm not able to perform a "Restart" or "Sleep". Other than that, it seems to be working fine. I did replace the PRAM Battery yesterday with a brand new one. Do you think I should try another PMU Reset? I don't want to push that button until I hear it's okay to do so.

Thx

I have it being worked-on at an Apple Service Center. They believe it might be the Power Supply. A common problem I hear. I will update this thread later when I learn more.

It turned-out to be the Power Supply. It was replaced and working like new. Thanks for all the help.
