thinkpad l440 cpu upgrade?

Dears,
when i decided to buy thinkpad l440 i was choose Intel® Core™ i3-4000M , it was 3 months ago. Really, this is laptop is very good but now i want to upgrade my laptop cpu to Intel® Core™ i7-4600M .
please any advise in the following questions:
1. is it possible to upgrade my laptop cpu to Intel® Core™ i7-4600M ?
2. my laptop still in warranty until 2017, so if the upgradation is possible is it can be made by lenovo or by myself? and the cost will be high?

Re: thinkpad l440 cpu upgrade?

If you do it yourself it will certainly be cheaper, but the CPU is not considered customer-replaceable, so it may affect your warranty status. If you can do the replacement in a professional manner, so it doesn't look worked on, probably nobody will complain, as long as you keep the old part and replace it back before getting service. The FRU of the i7-4600m is 04X4049. You do not want to get one marked "ES" (engineering sample). The ES parts may not be final versions

Re: thinkpad l440 cpu upgrade?

I have a 47w i7 4910MQ installed in my L440, it runs well, average idle temperature is around 42c, just make sure you use very good thermal paste. If you install a real quad core then you should upgrade your PSU to 135w, it will also work with 90w but you might need more than that. The heatsink in standard L440 does the job but if you want to be safe then you can replace it with the heatsink that comes with the Nvidia version of the laptop. Those are hard to find but i managed to get one with a quick google search :-)

I have an L450, looks like the heatsink is quite smaller on mine, I wonder if that i7-4910mq would overheat mine.

Re: thinkpad l440 cpu upgrade?

The L450 is 5th generation and will not have a socketed CPU, your CPU is soldered onto the motherboard and you will not be able to change it without replacing the whole board. Basically if your current CPU ends in a "U" then you are stuck with it... if it ends in an "M" or MQ then it is socketed and you should be able to swap it :-) That is one of the reasons the heatisink on the 5th gen motherboards are so small.
