[poushma]

How would you replace the motherboard and CPU of a dell inspiron 4150? I am updating a dell inspiron 4150 thats motherboard bit the dust, so i would like how to go about replacing, the motherboard, and installing the CPU on this computer model? It would also help if i were told good places to buy parts, like a how to identify processors i can use, and were to get them cheap?

The Inspiron 4150 (actually a rebadged Latitude C640, which I am familiar with) is a P4 machine that takes a Socket 478 CPU, and from what I've been reading on the Dell forums (such as this thread), the machine can take any SL6-series P4-M chip. As far as I can tell, the newer/faster SL7 series, badged as the "Mobile Pentium 4" instead of P4-M, won't work despite having the same CPU connector.

Wikipedia has a section in its list of P4 processors that should work with the machine. Your best bet to get such a CPU is probably eBay.

Dell's website has documentation on how to tear down the machine, so that you can remove the mainboard and replace the CPU.
