My original CPU is Core2Duo.
I opened my laptop and tried a DualCore cpu. It worked.
But when I returned my Core2Duo, the laptop boots then suddenly turned off. They are of the same socket type which is Socket P.
Why is my original cpu not working?
The tech support said that the original CPU isn't compatible with my unit.
I'm a Java programmer. Is there any workaround so that I can self-diagnose the problem. It will save me some bucks!
