Who upgraded i3 2350m of y470 to i7 2720qm? Tell me about it. Will there be any problems?

To be honest, there is no need to upgrade. Upgrading to the second generation notebook i7 is still at the elimination level. Moreover, the power supply pressure and heat dissipation brought by upgrading CPU are also devastating to old computers, and the cost of time and money far exceeds the improvement of performance. Personally, I suggest using this computer first, and I won't be willing to buy a new computer one day. You really don't have to consider upgrading.

This i3 version Y470 uses a 2-phase CPU, and the i7 quad-core version uses a 3-phase CPU. If i3 is directly upgraded to i7, there will be insufficient power supply. In other words, the performance of i7 2720QM will be unsatisfactory, and the pressure of power module will increase. In addition, the second-generation notebook CPU must be second-hand. Aging CPU+ aging motherboard+aging heat dissipation module+insufficient CPU power supply +CPU architecture elimination can be imagined.
