I have an older model Clevo P150SM laptop I am trying to get running for my granddaughter. She does not play sophisticated games, so this older laptop will play what she wants to play. Everything works great with a spinning conventional hard drive. However, I have a spare Samsung 500 gb SSD lying around not being used, and I am trying to swap the spinning HD with the SSD. My problem is that the bios cannot see the SSD. I have two different SSD's and the bios cannot see either of them, so I don't believe it is a defective SSD. I have a bunch of spinning HD's lying around, and bios can see every one of these. The laptop was manufactured in 2012, which might have been before the invention of the SSD. Any ideas on how I can get this antique laptop to see this SSD? Thanks for your assistance.
