Live or Die: CPU and MotherboardMy HP Pavilion Entertainment Notebook PC dv1227us died the second time in its period of existence last week. Out of all the notebooks I had--I had quite a few, just see this web site--this was the most expensive one I paid for. Most of my other notebooks hovered in $600 price range. This dv1227us costed $1600. And so far, it died twice, while my other more affordable laptops still lived happily today. The first time it died, I managed to fix it under warranty, which covered $750. It was about half the price of a brand new dv1227us. This time around, I had no warranty to save it, so I looked around on eBay for a motherboard/CPU combination. I bought one for $200. It was still a bit pricey, but I liked the notebook. It came next day. After replacing the motherboard, I now have some experience in diagnosing the failed parts. I can readily tell whether it's the main board that failed or if it is the CPU that failed. Here are the rules: If the computer powers on, but there are no change in the display (and you are sure that the display is working), then the CPU has failed. If the computer does not power on, then the main motherboard has failed. The CPU is probably ok, unless you know more about it. Chieh Cheng
