revoming 680e motherboard

How do I get the motherboard out of my handheld. I have taken out all the screws that I could see on the outside of the computer. The mother board still won't come out. It's attached inside right under the serial number. How do I get the screw out that is holding it together? Thank you for your help.

Look under the HP tag in the bottom, between the white part (The one that says Prod# and has the barcodes) and the certifications part (the one that says NOM, NYCE, CIB), u should try to either remove that tag or to make a hole on it. I made a hole by using a sharp tool and then removed the rests with my fingers, underneath it there's a screw, similar to the others, if you want to email me, i'll send you a pic of the exact spot where the screw is located.

Hope this helps
