Q:
During the past week, my HP Pavilion dv6000 had always been overheat until auto shutdown. Previously I could start it right after auto shutdown. However, yesterday when it turned off, I couldn’t start it any more. Fortunately, I have a backup of my documents, and then I called HP. They said this would not be the problem of the motherboard…
When I connect power wire to the laptop, blue indicator light is on. But on/off button won’t work. Could this be the problem that motherboard is broken? Or just some other reasons? What choices do I have?
A:
1): There’re many reasons causing overheat, such as broken components, design defaults, old driver, bad stability or sort of that. Any electric component inside laptop may overheat or get something wrong, including CPU, RAM, HD, GPU, LCD inverter, power supply and so on. Of course, it’s not that easy to find out the root of the problem. You need to find possible thermal parts carefully.
2): Except to change a fan, I suggest you blow dust off with a blower. Many times, the default of thermal system would cause the ponderance of the problem, generally a large quantity of dust pile up on fan, causing a thermal problem. Afterwards, CPU does heat continually. Continuous heat, when reach to a critical point, CPU would auto shut down. And then what? Just like the situation right now, some component might be burnt by accident.
