Fix ZenBook Duo ScreenPad+

My ASUS ZenBook Duo runs on Windows, and ever since a recent software update the ScreenPad+ has stayed blank. I have already restarted the laptop, updated display drivers, and checked every display setting I can think of, yet the second screen still refuses to light up. I need someone who really understands the Duo’s ScreenXpert software, ASUS Service utilities, Windows display & graphics driver interactions, and firmware/BIOS nuances to track down what the update broke and get the ScreenPad+ fully functional again. Remote diagnosis and step-by-step repair is fine as long as the final result is the lower screen behaving exactly as it did out of the box—brightness controls, touch, app launcher, everything. Acceptance criteria: • ScreenPad+ powers on automatically at boot without errors. • Touch, gestures, and ScreenXpert features work. • Device Manager shows no display-related warnings. • A brief summary of what was fixed and how to avoid a repeat. If additional tools or firmware files are required, just point me to official sources or share them during the session.
