I find these numbers to be very off actually. We have hundreds of laptops as well as desktops and the between dell and hp's we only seem to have problems with the dell's. What is also rather funny to me is the hp laptops that I have had at my home have Asus motherboards. Heck even my hp desktop had an asus motherboard and video card. Does anyone actually even know who makes dell's boards????
As far as the failure rates go what exactlly are they measuring for failures? Are these failure's due to HD's, Mem, Motherboards, CPU's, GPU's, etc...... Perhaps the reason for higher rate of failure from one brand to the next is due to the components used. I have a compaq that is 10 years old and still works fine. Then again I have purchased higher powered laptops that only last a year. Lets face it. typically in the past you got more for your money from HP, Acer, etc.. than lets say dell or sony. However, with a more powerful laptop comes increased heat. It should be a no brainer that heat is what kills a laptop faster than a desktop.
