Re: L520 Cpu Upgrade

2015-06-23, 23:07 PM

Seeing that this thread is still alive, I should have replied that I eventually updated the computer to the 2620M with no complications at all ... no driver problems. Of course, I can't tell you if there would be driver problems with the 2630QM.


I have also increased my RAM to 8GB and the L520 is quite a fast laptop.


I have no intention of adding an SSD, as I have had nothing but trouble with them in the past. I'm sure that one would increase computer speed, but I've never had an SSD live longer than about 3 months.

I also lenovo L520 and I managed to buy a processor i5-2410M and i7-2630QM. They both work . But my system is linux mint shows operating temperature 60-75 C. Video , especially flash and browser slow down , frequent errors and freezes . Size of stone i7-2630QM more and I can understand why this is happening to him , the cooling system is smaller . But why is this happening to i5-2410M? What is the cooling system is needed for normal stable work ?

I'm a bit late to the game but I can confirm that the L520 can take an i7-2720QM. It draws 66W while on Prime95, but doesn't complain about the 65W AC adapter - I have also been using a third-party 90W adapter though just in case. It's a pretty decent way to extend the life of a good value Thinkpad. I moved  up from an i3-2350M.
