I have 2 sticks of SD Ram 512 that I would like to put in a Dell Inspiron I2650. How can I find out or how would I know if the unit could handle these two stick and bring my existing laptop up to 1 gig of RAM. The machine is actually another family member who is going back to school and needs it if it works. All I can say is it went in a Dell laptop before. Dos anyone know how to do this? Thank you very much for the support that you bring.
