Q: black screen at startup
Hello. I have a Macbook Pro (2011); when I press the power button I hear the chime - but the screen stays black. A few times I have a gray screen that provides password help - although I never saw the screen to input my password. I go through the process and change my password, but I have to reboot the system..... back to the black screen. Any suggestions?

Try resetting SMC. Choose the method for “If the battery is non removable”.
