Yesterday night I put my computer to sleep with a functioning keyboard backlight, when I woke it up today morning I noticed that the keyboard backlight has stopped working!! I can confirm that both my Fn and spacebar keys are working fine! Pressing the Fn and spacebar keys together does not even bring up the small visual on the display which shows that the backlight mode has changed. I tried using the Lenovo Vantage app to turn on the backlight, but also to no avail. Lenovo Vantage shows me that it did an update to the "Lenovo intelligent thermal solution" driver to version 22.214.171.1247. I even rolled back the driver to its previos version using device manager to 126.96.36.199 but the problem is still persistent.
