Hi,
I have a Macbook Pro that experiences exactly the same issue.
- MagSafe working (green light)
- Fans bumping with stable frecuency
- Power button does nothing except make the funs bumping a little bit faster.
- MBP Doesn't do anything, no startup, no sound, no hdd start, no Superdrive start, nothing
What i did:
1- Before opening the topcase, the MBP was starting up and booting OS correctly (but with a display failure)
2- Removed the Battery and Memory cards
3- removed all the screws to open the Topcase
4- Removed the topcase without issues
5- Try to turn on to see how the Fans run and internal parts run -> NO Startup anymore!!!!
What I have tried:
- Reset the PRAM
- Reset the SMC
- Review all the cables on MB
Nothing helps.
Note: My Battery is completely dead. I don't know if this it's needed to make some of the resets.
I can't understand why just with the opening, its not more starting up?
Luci, did you find the solution?
