compaq docking station

[Marklc]

I have an old compaq docking station and can't seem to get it open. There are 2 push tabs in the back on either side to open the case. but then nothing else. Also a Key access ( no key of course ).on the side .. How does this thing open ??

the model # is cnt75mb21. and the computer is a compaq lte elite 4/50cx..



thanks ..
