Hello every one, i know when i bought my laptop (5150 Dell), it said if it got to warm it would not run as efficiently. A buddy of mine also bought the same computer, after listening to me talk about it. Both our computers have run fine for these months of use, but recently my friends computer has just become prone to shutting down without warning. After some googling we have found out that this is a design flaw in with dust collects and causes the computer to over heat. Dell has done nothing to solve this problem, which leads me to ask is there anything i can do so this doesn't happen to me, and shouldn't dell do something about this. If anyone else has a 5100 series from dell and is experience problems please visit this page.http://www.geocities.com/i5100dustproblem/index.html
