Hi Michbarany,
Welcome to Sony Community!
Thank you for your message. You should have provided the exact model name of your laptop so we could check the specifications. Is your laptop a VPCEB33FM (just like the one on the subject) ? We suggest that you replace the parts with the same specifications provided for your laptop to make sure that it will be compatible.
We recommend that you get some help from experienced people, Sony service center or a trustworthy computer repair service in your area.
Regards,
Jen
