Needs a new display or can be used for parts or with an external monitor.I purchased this renewed off Amazon a year ago so its basically in great cosmetic and working condition.  I took this on vacation with me earlier this week and I guess it got jarred around in my travel bag and caused the screen not to work.  When I arrived at my hotel and turned it on the screen flickered and went out (The Apple logo won't come on and the screen does not display).  When I arrived home I plugged it up via HDMI cable to my monitor and everything works great. It currently has Big Sur installed and the backlit keyboard, sound, hard drive works as intended. This computer has good battery life it just needs a display.  There are no dents on this was kept in a plastic shell case the entire time I owned it.  Contact me with any questions you might have.  Computer will ship out Monday.
