In sempteber 2008 I've bought my dv7 1070ed, since then I was really happy with this laptop. Never had problems with it, beside the dead battery, but most of them die after 6 months(that's why they only give 6 months warranty on batteries). Around a months ago I've noticed that the cooling fan is turning on more frequently while using the laptop. Last week tough, it was a very hot weather and my laptop turned off by itself. I've tried to turn it back on few times, I was able to log in and after than it shuted down again. The next day I was able to turn it on for an hour and run CPU Tester Pro, but after an hour of running it went off as well. The next day I was able to start and run fully the windows recovery, but after that it went off. Yesterday it shuted down after few seconds.
I can hear the fan is running, I can hear hdd starting up, but after few seconds it goes off. I was also able to update BIOS, but it didn't help either.
Is it broken cpu? are those the symptoms of broken cpu? because if it was motherboard I think it wouldn't go on at all?
I've found a cpu I would need for $160, seems to be a reasonable price, while in Holland I can get it for 400 euros.I also thought about getting some second hand laptop and I saw few nice ones for 200-300 euros. I would rather repair mine tough. I liked it so much.
