Thanks for the answer! I'll try it and repoting later Hi! Unfortunately, I did not think of it ... I found out about it later

Hello. I'm having some problems updating the ThinkPad t420. By default I have i5-2520m. After changing to i5-3210m, the notebook does not turn on. After that, I install my old i5-2520m, but it also does not turn on! Later I learned that before the upgrade you need some manipulations in the BIOS, but it was already late ... Thank you in advance Best regard, Boris
