The Lifebook will never work with a finger or plain stylus touch. It must have an appropriate Wacom Stylus. Various Wacom products will function but the original will fit the screen dock. An available source of an alternative , functional, and reasonable fit in the slot ( a secure fit and allows the lid to close normally ), may be found on eBay - See Item # 140504970431. These units do not require a power source but are interactive. This supplier has a very prompt and reliable service. Good luck. Paul W.

hello

Some of the letters stop working due to dust that stuck between the pad and board..Or due to degradation.

So you can try cleaning the keyboard with vacuum cleaner and clean properly between the keys.

If the keys still don't work you can replace the keyboard as it is replaceable.

Thank you
