I got Lenovo Thinkpad P16V Gen1 for testing and work – I got Intel i9 model with 32GB of RAM and 1TB of SSD – first thing I did is get new RAM and disk and get to update it. However, after I upgraded RAM with new (Crucial) sticks, on boot I got blinking ESC + F1 + F4 on keyboard. First ESC, then F1 and then F4 key. This is going on and on… Let’s check what I tried so far.
