Can HP ZD7000 video card be replaced?

The video card on my HP ZD7000 is out of work. Does anybody know if this is a replaceable part? I would discard the laptop if I have to buy a whole new motherboard. If it is replaceable, where can I buy a new or used video card? Thanks.|||Get ready to buy a new laptop|||It is not replaceable since it is integrated onto the motherboard.|||There were three or four different motherboards made for that model of laptop. Some had upgradeable graphics chips while others did not. You'll have to contact HP and ask them if your laptop has an MXM module in it. If you're willing to update your question to include additional information such as the serial number or a GPUZ reading, then I can help you further.
