Laptop CPU Upgrade

I have an Inspiron 15 3521 laptop with an i3-3217U cpu in it. I was curious about the possibility of replacing the i3 processor with a better one (i5 maybe). I understand that i would need to find a CPU that would be compatible. My question is in two parts. 1) Is it even possible to upgrade the processor on this laptop. 2) if I put in a processor with a higher clock speed that puts out more heat would the computer be able to handle it? Current TDP of the processor is 17W.

RE: Laptop CPU Upgrade

The CPU is soldered to the system board - so any upgrade requires replacing the entire mainboard.  There are likely boards with faster or more featured CPUs -- but the fact that you must replace both the CPU and board will raise the cost of the upgrade.
