Hi Teltom1,
Welcome to Sony Community!
Please verify the model name of your laptop. The PCG-2J3L is the chassis number of the unit. You may check it on the lower bezel of the screen or on the top right of the keyboard then look for the model that starts with "VGC".
Once you found it, go to esupport.sony.com and search for the manual.
Regards,
Jen
