Replace hard drive on ASUS ee PC

I have an ASUS eee PC model 1005HAB with a crashed hard drive.

This model netbook does not have a "trap door" on the back or a slide out drive bay. It appears I have to take the entire back off of the unit to access and replace the drive.

I've tried removing the 4 corner screws; the back case won't budge.

I'm trying to locate a service/repair manual. ASUS' web site doesn't have it available as a download and I would rather not pay an unknown source found in a Google search in advance for a manual that may or may not be the official one (I've been burned on this before).

Any ideas on where to find a legitimate download of ASUS eee PC repair manuals? Thanks in advance for your help.

 

Here you go. Not the repair manual but hope this helps.
