Since Page Up and Page Down still work, but Home and End fail on both the physical keyboard and the on-screen keyboard, this points more to a Windows keyboard setting or app behavior change than to a hardware fault.
Try these checks in order:
- Check Accessibility keyboard settings
- Windows 11: go to Settings > Accessibility > Keyboard.
- Review Sticky Keys, Filter Keys, and related keyboard options.
- Turn them off temporarily and test Home and End again in Chrome.
- These settings can change how keystrokes are handled, including ignored or altered repeated/special key behavior.
- Check for Windows updates
- Go to Settings > Windows Update.
- Install the latest updates, then restart.
- Microsoft notes that special keys not functioning can mean the PC does not have the latest updates.
- Test whether the issue is text-cursor behavior vs page navigation
- In Windows text editing, Home and End are commonly used to move to the beginning or end of the current line, while Ctrl + Home and Ctrl + End are used for the beginning or end of a document.
- If the problem is only inside editable fields, test Ctrl + Home and Ctrl + End as well.
- Check whether Chrome is treating the keys differently than expected
- The available context confirms Home and End are standard navigation/editing keys in Microsoft apps and Windows, but it does not document a Chrome-specific setting for restoring page-top/page-bottom behavior.
- If the keys fail only in Chrome and not elsewhere, that suggests an app-specific behavior change rather than a Windows keyboard failure.
- If special keys still do not work correctly across apps
- Recheck Settings > Accessibility > Keyboard.
- If using Microsoft keyboard software, review customization in Mouse and Keyboard Center, because key settings and configurations can be changed there.
Based on the symptoms, the most relevant first actions are:
- Turn off Sticky Keys / Filter Keys
- Install Windows updates
- Compare behavior in Chrome versus another app or text field
