Yes, I know: if I could free myself of the damn thing I’d’ve* not had to worry about a hot laptop on my lap. Last year I realized that while the Latitude was nice and comfy in winter, it was hell to work on in summer, even with air conditioning. Wasn’t good for the machine either, I assume, as I’d noticed that the pc’s did strange things in an overheated room and ran super hot themselves until we added the a/c. So I bought a laptop fan plate that you plug in via usb connection and that has worked wonders; for the Dell, as well as now the Mac which has taken over the fan unit as well as my computer time.
The only thing I need to modify on it is the sharp edge which cut into just above my knee. A strip of foam glued to this should solve the problem.
