Cowork AI Agent Causes Keyboard Input Issues on Windows Laptops

Keyboard Input Failure After Using Cowork AI Agent

A Windows laptop user experienced severe keyboard input issues after working with the Cowork AI agent. The problem manifested as only the first few keystrokes registering properly, with subsequent keystrokes either not appearing at all or appearing sporadically (approximately 1 out of 10 keys typed).

The issue persisted even after restarting the system, forcing the user to rely on the onscreen keyboard to type their password for login.

Specific Fix for Dell Latitude 9430

After trying numerous troubleshooting steps, the user found a Dell Latitude-specific solution that resolved the problem. The fix targets the embedded controller on Latitude models and clears stuck key states:

• 1. Shut down the laptop completely
• 2. Remove the power cable
• 3. Hold Fn + S + B simultaneously for 10 seconds
• 4. Then hold the power button for 30 seconds
• 5. Plug the power cable back in and restart

This procedure resets the embedded controller on Dell Latitude models, specifically addressing the stuck key state that was preventing normal keyboard input.

The user shared this solution on r/ClaudeAI to help others who might encounter similar issues when using Cowork on Windows laptops, particularly Dell Latitude models.
