You would need to buy from ebay.com - seems to be 15USD plus extras. As for the backlighting - AFAIK, check if there is a model with backlight AND your laptop should have a free port near the keyboard port which seems like a backlight port. If no model has B/L support - try to see if the keyboard used in the 1564 is also used in any other machines - check whether they have B/L support. Its a bit tedious - but you will get your answers.
