Yeah you hare an investment you want to keep.
OK, I will say go ahead and try to remove only the retainer and slip out the shard drive. You do not actually open the hard drive itself, jut remove it form the laptop.
If you find the problem is the hard drive, you might get a replacement for under $50 if you shop around. But you will have to install the system again.
But I will guess it might work when you put nit back in. It might be a loose connection.
Worth trying.
