Bought the laptop about 1.5 years ago. I 95% of the time just close it to sleep when not in use. Rarely shutdown or updated.
The other week I finally tried to restart it and when it loaded up it was just a black screen that said no bootable device found. I had to startup holding the command key and load up using time machine. This has happened twice now. I am now just putting it to sleep and have been avoiding any updates or restarts. Wondering if anyone can point me in the right direction to fix this problem.

If it pops up and says no bootable device found on a black screen, it sounds like it's trying to boot to Windows but is failing to do so. Have you ever installed Windows on the MacBook Pro?
Next time it happens, try booting up holding the option key. It will show you a list of bootable partitions, and you should be able to select the main system partition.

Try Safe Mode. Power down. Power up and hold shift key down until the Apple logo appears.
