Hi, I have a 15" Macbook Pro 5.1 running Leopard 10.5.8.

It's been working pretty much fine until recently when it just wouldn't turn on at all. I tried an SMC reset by taking out the battery and adaptor, holding power for 5 seconds, replacing battery and adaptor and turning on but still no response. However, I can get it to turn on by removing battery and adaptor, holding down the power button and replacing the battery and adaptor still holding the button down, then letting go and pressing it again for some reason.

Unfortunately this hasn't fully fixed my mac, it works but the fans continuously run full speed from power up, it doesn't respond to the lid being closed, it doesn't respond to light so the screen stays fully on and the keyboard doesn't light up, all typical signs of an SMC reset needed. However if I turn it off I'm back in the same position as before..

Is there any way to fix these problems without SMC reset or is the way to reset it different on this model? An apple store isn't really possible because I'm abroad at the moment and there isn't one near by, plus they'd find a way to charge me loads anyway because its waaaay past warranty.

Thanks in advance!

MacBook Pro, Mac OS X (10.5.8)

    Sounds like you've done the smc right, although the second part is quite strange amd not normal.  You can try a pram reset (though it might not do anything, but won't hurt either)  Power off, hold the option, command,P,R (no cmmas) and poer up, hold thee keys brfore the start chime, continur to hold these keys till you hear the chime 2 time. Reboot.  You can also try a safe boot sometimes this fixes stuff. Power up holding the shift key and continue to hold till you see the progress bar then release and let it finish booting.  Shut down then try booting normally. When you have accesss to an Apple store I would bring it in, they diagnose for free then tell what a repair costs, usually a flat fee if there is no liquid damage. About 1/3rd the price of replcing and they repair what needs to be fixed.  Hope this helps and holds you overr.  All the Best

    Take the computer to an Apple store or an AASP.  Whichever is more convenient for you.  You can get free diagnostics at an Apple store (unknown about AASPs).  This way, you will know exactly what is wrong.  You will have to pay for the repairs if you do not have Apple Care.

    You can't know how to repair something if you do not know what is wrong with it.  Take it in for your free diagnostic test.  After you find out go to the Do-It-Yourself Laptop Repair, YouTube's 'How To' video tutorials and FixYa websites for DIY instructions.
