I tried to install a QX9300 CPU in my HP Pavilion dv4-1150br laptop (uses GM45 Chipset) but did not work. The laptop not turn on! Why? Some configuration to be mabe or compatibility is limited by the motherboard manufacturer? (Note: HP support is terrible and does not give any useful information!)
Compatiblity is limited by the system manufacturer, in this case Hewlett* Packard*, so I would recommend contacting them so they can provide you a list of supported processors for your Hewlett* Packard* system.
