I did. It decided to meltdown 2 weeks or so after the extended warranty expired in 2010. Vowed at that point to never buy another laptop again, it was a higher-end HP with a 17" widescreen. Dedicated graphics was the problem there, the nVidia card overheated and took the motherboard with it.
I prefer desktops because I have access to all the parts, and can easily get to whatever I need and can move parts in and out as technology changes.
Did you try getting the graphics chip reflowed to see if it would fix it? I had a dv4-1155se with bad graphics, and had a guy reflow the graphics chip and it brought the system back to life. It was a 2008 model.
