MacBook pro won't turn on! No start up chime! Just drive & fan noise.

Hi guys hope you can help!


My MacBook pro won't turn on! There is no start up chime, but I can hear the fan and drive come on. The screen also doesn't turn on.

I have tried the "PRAM" but no results. I have also tried holding down the power button with and without the power cord, but I still only get the drive and fan noise, no start up chime or screen.


I initially shut it down to cool off over night. The next morning it wouldn't come on. Only what I have described.



Can anybody please help with this?


Thanks!

I had the same issue. Mine was MBP Mid 2010. I tried to reset NVRAM, PRAM, and others tips I found in the web. Unfortunately nothing worked.


And suddenly I had this idea in my mind. What really worked for me was:
1. Opening the backcase

2. Pull out the battery

3. Try holding the power button for 20 seconds without the battery or Magsafe attached (to empty the remaining electricity on the board)

4. Put the battery and everything back.

5. Now turn on the mac as normal.

6. Thanks god. My Mac was back to life again.

I had the exact same issue... Macbook Pro late 2008 with Core2Duo. Went to all the steps suggested in the knowledge base, tried to reset the SMC, but to no avail. Took it to the Macstore in Mexico, the wanted to replace logic board for $800.... Finally, I sent it to a logic board repair service, where they "fixed" the logic board for $200. It worked perfectly for 4 months, then happened again 😟


Any ideas?? I would appreciate any help!!!!!

Having the same issue here. It makes a noise inside (sounds like the hard drive kicking up) the fans start spinning and the light on the front turns on (the light on the little piece that allows the monitor to flip open). I get no startup chime or anything on my screen. I tried resetting the NVRAM but it doesnt seem like it does anything. I also tried resetting the SMC and nothing either. It is from 2009 and out of warranty so i can't take it in. How can i fix this without spending a fortune?

I have same issue with MBP late 2911 but purchased in 2012,

I got battery sensors issue so removed battery and using as desktop without battery.

Working but slow but since yesterday at the startup there is apple logo and blow that a bar that takes 10 to 20 min completion (?scan) than after completion MBP stops and require restart but again starts with Sam scan etc with NO startup tone chime. I don't get startup tone I think this us the major issue. I wanted to start safe mode but there is no seat up tone so shift key won't work even if u press same thing happens.

Second thing if you could help

I have USB net how can I start it because I can open MBP

Please help ASAP

Thanks
