For first, hi there I have an mid 2008 MacBook Pro, some time ago (about 4 month for now) i observe thats, my computer dosen't charge propertly (only for 75%, eg.) so i've read some opinions over internet and perform an a SMC reset, after that my computer dosen't start anymore. How I've done: 1) Turned off computer 2) Remove Battery 3) Hold down power button for 5 sec 4) replaced battery 5) trying turn on computer, but thats failed. I cant turn on it anymore. Thanks for any advice, Regards, Michael.
