Re: upgrade i5 to i7 ?

The CPU is socketed, so you just need the CPU itself.

Re: L540 - upgrade i5 to i7 ?

Good day and welcome to the community.

 

According to the FRU BOM: https://download.lenovo.com/parts/ThinkPad/l540_fru_bom_20140807.pdf , there are compatable i7 CPUs (see page 2).

 

The installation looks straightforward. See pages 104-105 of the hardware manual: https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/l440_l540_hmm_en_sp40a26004_03.pdf

 

Hope this helps.

Regards.
