As long as the fans come on appropriately and the CPU temp stays in the normal range you should be okay (if a bit warm). We had customers complain that they'd used the machines on their knees and gotten blistered. The only answer is, "Don't do that." I know that's not very satisfactory, but it's a good machine otherwise and you just have to know its shortcomings. I understand that the newer D-series machines are better, but I'm no longer with Dell Portables Engineering and don't have access to data on them. -- Jerry Dunham M3 Design, Inc. jdunham@m3designinc.com (512) 218-8858
