Hi all, I own 4 Sony Vaio SVP13, 3 of them working good but the last one, bought on Ebay a few days ago has arrived in pretty bad shape.
I've fixed it with some spare parts but after booting to Bios to do a clean install I realized the Model, Serial, Tag number and UUID are as RESERVED/ missing...
out of curiosity I went to check my other 3 SVP and only one has Info matching, other 2 are either missing or wrong.
I don't know how or why has this happened because I got them all second hand.


I would like to fix this issue in all of them as I really like them and already tried one DMI Tool, I can change the values using it in Windows but It will not update, it returns some D8 Code and can't save the changes.
I've read somewhere it might have something to do with the exe version... but I can't find much about it since it was removed from their Website.

Is there someone who can guide me through the process and point me to the right tools?
I'm willing to do it myself if someone guides me and if I can, never done this before.

I can post backups from all Bioses of course but I need still to back them up. All those numbers are also visible on the Laptops, so I have all the info's.

Please let me know if someone can take some time to guide me...

Thank you in advance!

Really no one able to help me?

I've been reading around but don't even know where to start...
