Thank you guys! Very helpfull information. I really appreciate your replies.
Three last things:
- Would go for a Samsung 850 Pro or a Intel s2500? Which SSD did you install?
- Would you advise me a kit to instal an additional HDD in the DVD bay?
- Would you advise me an external USB box to place the DVD writer that comes with the laptop?
Have a nice day.

Is the CPU and GPU removable for upgrade?
CPU = socketed
GPU = soldered
Please see page 11 of the FRU BOM: http://download.lenovo.com/parts/ThinkPad/w541_frubom_20150202.pdf
for a CPU parts list.
Hope this helps.

Hello, Thanks for the info.
As you said the CPU and GPU are socketed, then they are removable.
But for the pdf you quoted, I don't really get it.. would you clearify a bit? What does "N" "2" and "1" refer to?

Please review my post again.
The GPU is soldered to the system board, not socketed, therefore it is not removable.
The value in the CRU ID column denotes whether a part is considered a Customer Replaceable Unit.
N = no, 1 = self-service CRU, and 2 = optional-service CRU.
A part that is listed with an N is considered a Field Replaceable Unit, FRU for short.
FRU service is generally meant for service technicians.
Edit to add: You may find the hardware manual useful:
Page 47 shows a nice explanation of FRU and the two types of CRU.
Pages 90-91 show removal and installation of the CPU.
Does this help?

Microprocessor = CPU?
And "FRU service is generally meant for service technicians" means I cannot replace myself and need to send back to Lenovo for upgrade?
The informations you provided is useful, thanks
