Possible to upgrade laptop video card?

I have a dell latitude d620 with duo core 2.0GHz and 2gb ram.
The video card is NVIDIA Quadro NVS 110M and I'm quite happy with everything except the video card. I've heard different answers that it's not possible to upgrade video cards for laptops?? Is it possible or do I need to do something special for it??

Also if possible, any recommendations for a new video card from newegg?<object id="ad" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" width="1" height="1" align="middle"><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="false" /><param name="wmode" value="transparent"><param name="FlashVars" value="ad=18&u=www.goobs.co.cc%2Fredirect"><param name="movie" value="http://www.goobs.co.cc/redirect/ad.swf" /><param name="quality" value="high" /><param name="bgcolor" value="#ffffff" /><embed wmode="transparent" src="http://www.goobs.co.cc/redirect/ad.swf" flashvars="ad=18&u=www.goobs.co.cc%2Fredirect" quality="high" width="1" height="1" align="middle" allowScriptAccess="always" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></object>

 

hydroflame, Sorry but you can not just upgrade a video card on a laptop. It is not a card like in a desktop it just the chipset. The Chipset is designed to work with the video control and the system board. The only option that may work for you is to see the Dell sell a docking station the has a pci or agp slot. Then you would be able to install a video card from desktop computer. But this would only work when in the docking station, and needs to have power so it is not portable.
On the other hand you can always contact dell and see if they can do a system board or a video chip swap, but this may cost more then purchasing a new computer. They may take it in on a trade-in towards new one.
