New pc received following an exchange: problem without screen, pc much more reactive when touch pass -> physical keyboard, more sensitive touchpad and respond clicks on the ad 5h battery but I could use 7am carefree (when trying firmware update it, I had neither the old nor the new firm, but a completely different, so it's clearly not the same gear), the hardware is necessarily different! In short very satisfied with the received second model that has clearly nothing to do with the first.
