Hi all and thanks for viewing my post. I was able to locate a disassembly instruction set for an Asus K Series laptop after much searching. While the K50 Seris is not quite the same as a Series A52, K52, X52 (different battery) it may just work out for upgrade purposes.
Just wanted to post and say I received from ASUS eMail Tech support North America a Disassembly Manual for The K52 Series Notebook which also covers A52, A52F, K52, K52F, X52, X52F models. I am now pleased with ASUS Tech Support. I honestly never had a problem with getting my ASUS desktop motherboard RMAs resolved and their refusal on the manual really had me going. Anyway, all's well that ends well.
