A bad SSD hard drive will result in a no-boot, but you should still see the bios load and classmate splash screen. It almost sounds like your screen or the cable connecting your screen has gone bad. Or, you may have lost your motherboard.

On the off chance that it may be a memory issue, you may want to open the memory compartment and reseat the memory modules. Most computers I've worked on will give an audible beeping alarm when the memory is not in correctly, but who knows.

After that, I would contact the company that makes classmates - they have a service number. I believe you can find more info on the classmate on the FIRST website.

In the mean time, remove the hard-drive from the computer and hook it up to another to see if you can read the data, as the first poster suggested.
