Windows 10 1709更新后三星XE700T1C自适应亮度无法关闭求助

Hey Jonno, sorry to hear that the brightness control on your Samsung XE700T1C went haywire after the 1709 update—super frustrating when basic controls stop working like they should. Let’s walk through some targeted fixes that have worked for similar hybrid devices:

• Roll back or reinstall display drivers
  The 1709 update often messes with display drivers, especially for older hybrid devices. Here’s how to tackle it:

  1. Open Device Manager by typing devmgmt.msc in the Run dialog (Win + R)
  2. Expand "Display adapters"—you’ll likely see Intel HD Graphics for this device
  3. Right-click the adapter, select Properties > Driver tab
  4. First try rolling back the driver; if that option’s greyed out, uninstall the driver (check "Delete the driver software for this device" if available)
  5. Restart your device—Windows will auto-reinstall the driver, or you can grab the specific model driver from Samsung’s support page for XE700T1C (stick to Samsung’s drivers over generic Intel ones if possible)

• Reset power plan settings to default
  Power plan glitches often override manual brightness controls. Let’s reset them:

  1. Open Control Panel > Power Options
  2. Click "Change plan settings" for your active power plan
  3. Select "Restore default settings for this plan"
  4. Apply changes, restart, then test brightness adjustment again

• Force-disable adaptive brightness via Registry
  Since you already toggled off adaptive brightness in system settings, let’s shut it down at the registry level (back up your registry first just in case):

  1. Open Registry Editor by typing regedit in the Run dialog
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation
  3. Look for the DWORD value AdaptiveBrightnessEnabled and set it to 0
  4. Also check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Monitor for any adaptive brightness-related keys, setting their values to 0 if present
  5. Restart your device to apply changes

• Run the Windows Power Troubleshooter
  The built-in troubleshooter might catch hidden power-related conflicts:

  1. Go to Settings > Update & Security > Troubleshoot
  2. Select "Power" and run the troubleshooter
  3. Follow any recommended fixes it pops up with

• Check for Samsung firmware updates
  Even without a BIOS menu, some hybrid devices get firmware patches via Samsung’s own software. Install Samsung Update if you don’t have it, scan for updates, and apply any available firmware or driver patches specifically for your XE700T1C—this can fix post-Windows-update hardware miscommunication.

If none of these work, a repair install of Windows 10 1709 (keeping your personal files) might resolve corrupted system files that the update left behind.
