[quote author=“jang”]Hello there. I have this TR2 without any other markers except for the PCG-491P model indicated underneath. Are drivers model specific? Want to reinstall this unit.
Is there also bios upgrade for these notebooks?
Thanks.
I think Sony uses the model # stamped on TOP when cataloging drivers and whatnot. See SH*T lost the link…but it’s out there. Anyway, my TR3 is stamped PCG-4A1p and that was not relevent on the Sony support website. So anyway, I just chose Tr3 and got all i needed.
