L420 - 7826A54: CPU Upgrade

Hello to everyone,

I have a Thinkpad L420 - 7826A54, the version with the i3 2310M cpu.

 

Is it possible to upgrade it to an  i7 7260M?

There is a version of the L420 with the i7, so it should work, shouldn't it?

 

Thanks for your help!

Did you mean i7 7620M?

Should theoretically work. Same socket.
And if Lenovo sells one, a better chance.
(What model of L420 has a i7?)

But, there may be other differences in the laptop,
cooling, power, bios support, etc.

Best bet would be a i5.

Thanks for your fast reply.

 Oh, of course, it is the wrong type of i7...

 

Here you can see. You can choose it in the customizing step of your order of the l420 I have.

Do you know how I can find out whether it runs or not?

Hi,

I might be seven years late, but what it the latest processor that the Lenovo ThinkPad L420 can support?

 

Thanks in advance,
