Hello, thanks for reaching out. I'm Ace, one of the Independent Advisors.
Your touchpad click-and-drag issue is likely caused by incorrect settings, driver conflicts, or firmware limitations. Since you've already updated and reinstalled the drivers, the next step is to check the touchpad settings in Windows.
Go to Settings > Bluetooth & Devices > Touchpad, then expand the Taps section. Ensure that Tap twice and drag to multi-select is enabled. If this setting is missing or disabled, you can manually enable it using the Registry Editor by navigating to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PrecisionTouchPad
Look for the TapAndDrag entry and set its value to ffffffff to enable dragging.
Let me know if this method works.
Thanks!
