How do I update my laptop's CPU?

Generally, the notebook cpus are soldiered to the board. I am not sure it can be done.

Which CPU do you have now and what do you want to upgrade to?

I have a Intel Core Duo T2300E. Don’t know what I can upgrade too.

I thinks its bad idea to upgrade your CPU. First of all dell does not sell authorized CPU parts and a google search did not bring up any CPUs manufactured by any trusted brands. Also the CPUs themselves will be quiet expensive. I have never heard anyone upgrading their laptop’s cpu. But I do know they charge well over $ 100 for changing over the CPU of a regular desktop at most shops. Is there a reason why you need to upgrade (because quiet frankly i think an Intel Core Duo is quiet fast) ?

fyi. a similar question came up on CNET LIVE a while ago and Tom Merrit even suggested that it’s a bad idea to upgrade your laptop’s CPU

Well, wouldn’t a trusted brand be Intel? I’m sure you can buy stock Intel cpus. As for cost, wouldn’t this be cheaper than buying a new laptop altogether? The Intel Core Duo is alright…it is pretty slow for apps that can only use one processor.

Well,obviously only an Intel processor would fit the socket providing it is not soldiered to the motherboard.

What would you suggest that would be faster for apps that can only use one processor, shared3?

I don’t know what cpus are compatible.
Does anyone know where I can find this information?
Also, how can I determine whether my processor is soldiered to the motherboard?

any cpus use 478pin are compatible. but D620 alreay have a T5600 cpu,I think it is enough for most of works.

I have a Intel Core Duo T2300E though. And does this mean Core 2 Duos are supported? That is the only requirement? There are no BIOS limitations or something like that?
