I still can return it, yet it works gret, and just looking for ppinions on if it was a good deal.

Now for the topic question. I hear about overclocking a lot of this forum and how it can get my processor speed(1.83 duo i think?) up some. I really dont know what it is so looking for someone to explain it. Along with this is it dangerous to the laptop or are there risks? If its riskless should i even attempt it on this laptop?

Sry if its a lot just getting into the pc sphere. Playing UT3 and loving it

You probably could overclock the graphics card via Rivatuner but with the cooling of laptops, it wouldn't be very wise.

As for processor and ram, you have to overclock them through BIOS and as laptops and pre-built PCs aren't designed for overclocking in the first place, they shouldn't have required BIOS tools to do it either.
