MacBook Pro doesn't turn on
I looked here for a solution to my problem but nothing helped me. I was using my macbook pro copying some pictures from an usb key to a folder, but suddenly my laptop turned off. Here it is what i tried to do
I tried plugging in the charger
i removed the battery and plugged it again after 10 minutes
i tried to remove the battery, plug in the charger and try to boot
i tried to remove the battery, pressed the power on button, then connected the battery again, tried again to boot pressing the button and cmd for 10 seconds.
i tried to boot the mac pressing the key combination SHIFT-CTRL-CMD- Power button for ten seconds
I removed the HDD and installed the older one
i switched the RAMS
i removed both and one ram too
One month ago i had another problem with my laptop and the technician installed a new hdd. My laptop worked until today
What do you suggest?
