I would start by connecting the SSD to another computer to see if you can access the files. You can buy an SSD to USB adapter for $20 or so from Amazon. Be sure you look carefully at drive compatibility. It's likely you have an M.2 drive. There are different keying slots on the connector for these drives so make sure you get a compatible adapter. Before plugging in the disk, open Disk Manager and see how many disks there are on the test computer (the primary HDD will show multiple partitions and CD drive(s) or other HDD will show as Disk 1, 2, etc. You may need to mess with the View option but the default should be OK. Shut down the PC and plug in the USB adapter. Disk Manager should show another disk number. Itshould appear similarly to Disk 0, but the number of partitions may vary. If the drive shows up, run a disk checker to exercise the drive fully. If the drive doesn't show up, you have your answer (SSD is bad or the adapter doesn't work which is unlikely). That's how I would start. Make sure you use ESD precautions when you are inside the laptop and handling parts. It's possible to zap something otherwise. Let us know what happens. I don't have a "quick" fix as that would just be throwing darts.
