You determine if the heatsink, fan is designed for the higher watt output? And the CPU power supply isn't ready for such a change unlike desktops.
In fact I may take a bet you are applying what you learned in desktops to laptop upgrades. If so be aware that CPU upgrades in laptops are rare to never seen events.
I'm in the process of trying to upgrade my laptop. A VAIO VGN-FE28H it has the T2300 1.66GHz processor which I am looking to upgrade. I dont research and know that the Motherboard and FSB dictate the available upgrades along with the BIOS.
The problem is I can't find the details to this I've tried using CPU-Z and HWinfo but no value for FSB appears! I have a Intel i945PM chipset if that helps.
Could someone tell me if a T2600 would work or better CPU that would work? Or just how I would figure it out myself.
