After the recent 24H2 Windows 11 update we have seen a number of Lenovo laptops that appear to have developed a keyboard problem. The keyboard becomes unresponsive at startup. Reboot and it works fine – until the next reboot, when it is again unresponsive. The keyboard only works every other reboot. An annoying issue, to say the least. From what we have seen it effects numerous T-Series, Yoga, and X1 laptops with 8th and 9th generation Intel Core i5 and i7 processors running Windows 11 Professional.
