Question : Problem: HP All-In-One 135d Printer

Any know where I can get an service manual for HP All-In-One 135d Printer.
I need to take of the outer cover to fix a loose battery holder, but I am not sure how to get to it.
I can see it, but can not reach it, need to take the cover off to get to it.
I know that if I try and get one from HP they won't gave it out, maybe someone might have one on hand.
