My keyboard is malfunctioning by randomly repeating keystrokes, with no discernible pattern or specific key affected. However, when I disconnect the keyboard and plug it into another computer, it operates without any issues. Additionally, the laptop’s built-in keyboard functions properly without any problems. Strangely, this problem only occurs when the laptop is connected to a power source, and not when it is running on battery power.

I have attempted several troubleshooting steps, including restarting the computer, enabling filter keys, adjusting the keystroke delay setting, physically removing the battery, reinstalling the keyboard driver, and completely draining the battery before turning the laptop back on. Unfortunately, none of these solutions have resolved the issue.

The only way I have found to use the keyboard without the repeated keystrokes is by unplugging the laptop and running it on battery power. However, this is highly disruptive to my workflow. I would greatly appreciate any assistance in resolving this problem.

  • OS: Windows 10 Home (64 bit)
  • Laptop brand: ASUS
  • Processor: Intel Core i5 -2450M CPU @2.50GHz
