Hi Ulrik1000,
Thank you for considering Sony Community!
Your Sony Vaio SVP132A1CM is not being recognized by our system. Probably that's not the right model name. If you are not quite sure what exactly happened, if you formatted it already or not, you may consider the steps here to isolate the issue: https://esupport.sony.com/US/p/support-info.pl?info_id=773.
If Assist button is not working anymore and you are decided to format the unit, try resetting it using F10 key. Follow the steps here: https://us.en.kb.sony.com/app/answers/detail/a_id/35585/.
Regards,
Vincent
