I got it picked up on Monday afternoon (approx 4:30PM). I got it back on Wednesday
They updated the BIOS, replaced the keyboard and... REPLACED THE HEATSINK!!!
All this and my warranty expired in January. So, I can't say enough good things about Dell. They really stepped up, admitted to the SmartStep's problem and fixed it in a VERY quick timeframe.
Well... they didn't say it was the motherboard. They didn't say it was the memory or the hard drive.
They admitted it was an overheating problem. The keyboard fix was probably just the removal of the film (which has been proven is a pretty good fix w/making the unit cooler)... so that's great. They also cleaned it out and "fixed" the heatsink... don't know exactly what that was but it's better than nothing.
So, considering my warranty was up, they could have just told me "tough... we're not doing anything for you." But they didn't do that. So I say "Good going Dell." Besides the overheating problem (which didn't start until about a year after I had the computer) I can honestly say that I've been thrilled with this laptop... I think it works great.
I specifically referenced this board and told him I knew about the heating problems... he then went and checked it out and then came back and acknowledged it. So, you may want to request a supervisor or something like that.
Good luck with the new fan... I'm sure it can't hurt.
