I am going to replace the motherboard in my dead Toshiba Satellite 5005-s504 laptop and am having trouble opening the case. I have removed all visible screws as well as the keyboard. The lower half is loose, but seems stuck at the rear about where the phone jacks are. I don't want to force it for fear of breaking something. Any advise? Do you know where I can find detailed disassembly instructionsfor this model??
Thanks,
