Lenovo G400 Processor Upgrade

I have a Lenovo G400 with Intel Pentium 2020M processor and I want to upgrade it into Core i7 3740QM. I just want to know if it is compatible before I buy one. Thanks.

Hello Niwa

 

Thank you for using the Lenovo forum

 

Best thing to do is chack the hardware manual on the lenovo support page, it will provide you with the details on if that is compatible or not.

Re: Lenovo G400 Processor Upgrade

This post shows the I7 -xxxx options for a G400 machine.

 https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/G400-20235-Processor-Upgrade/td-p/22380...

 

What model of the G400 do you have? Do you have the Intel HM76 chipset or the Intel HM86 chipset? The I7-3740QM is not in the list.

Re: Lenovo G400 Processor Upgrade

The 3 I7 processors in HMM are the I7 processors supported by Lenovo.

If you use I7 other than the 3 listed, your machine may not boot, may have power supply issues, etc.
