Hi @eke ,
Here is a link to the service manual for your laptop.
Scroll to p.28 to view the necessary pre-requisites and then the procedure to remove the SSD.
Once you have it removed you should be able to insert it into another PC with the appropriate mSata connection as an extra drive and hopefully retrieve your files or you may have to purchase an adapter to suit your "host" computer's available spare connection type, e.g. there are mSata to sata adapters, just search online for the appropriate type.
Hopefully this is of some help
