I have a 2013 Macbook Pro 15 inch i bought from ebay. it has no ssd. i bought a new ssd and it will arrive shortly, but when i turn on the machine, the fans kick on, the processor gets warm, but the screen stays black. In my previous experience, the screen turns white with a grey folder flashing with a question mark. is something wrong with the graphics or display? or is that expected with no hard drive? it appears as though there is not water damage. thanks!
