Q: what does the red light indicate

My computer won't fully turn on.  The Apple icon appears then the screen goes to blue and stays that way.  I ran the battery down yesterday and now it is plugged into the charger and the light goes from green to red.   The computer is off now and plugged into the charger.  What's next?

    Try these steps:


    Restart your Mac with the Shift button pressed.


    - Shut down your Mac

    - Wait until your computer turns off and after that press the Power button

    - Right after you hear the startup tone, press and hold the Shift key

    - Release the Shift key when you see a grey Apple sign and the progress bar below this sign

    - Once you see Desktop, start a Disk Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)

    - Click on Verify Disk and then, if asked to fix problems, on Repair Disk

    - After this, click on Verify Disk Permissions and then on Repair Disk Permissions

    - After the process is finished, shut down your Mac and turn it back on after about 30 seconds


    Apart from that, take a look at this Apple article and follow the instructions on Resetting NVRAM shown there: How to Reset NVRAM on your Mac - Apple Support


    Take a look at the steps suggested by Apple in this article:

    The red light indicates that the battery is being charged.  Let it sit for an hour or so and then try to start it.  If no success, try a SMC reset:
