kakagi, Thank you very much for joining the Intel® Processors communities.
In this case, I just wanted to let you know that before purchasing any type of processor for your laptop, we recommend to get in contact directly with the manufacturer of it, because the compatibility of a processor will not only depend on the socket type, it will also depend on the BIOS the laptop has, the microcode in the BIOS needs to be capable of supporting that processor as well, so we recommend to check with them first.
To answer your question, on the link below you will find a list of Intel® authorized distributors for USA. Remember that the processors that are sold to end users are the “boxed units”, those are the ones you use to build your own personalize desktop PC. The mobile/tray processors that are used in laptops are sold directly to the manufacturer of the laptop so they can build their products, I just wanted to let you know that information in the case you might not be able to find the processors you are looking for. Additionally, the boxed units have 3 years of warranty with Intel, the warranty for the mobile/tray units is provided by the manufacturer of the system:
Any further questions, please let me know.
