The video below shows some tips on how to fix your battery pen: PEN68 or PEN68D. (NOTE: PEN68 is for graphic tablets, while PEN68D is for tablet displays.)Below are the steps for your reference:
- Check if the battery is inserted in the right direction by ensuring that the positive side of the battery is towards the positive terminal.
- Your battery may no longer have power, so replace it with a new one.
- Check if the negative terminal is stuck. If it no longer protrudes, it would result in loss of contact. You can fix it using a tweezer or a pocket knife to make it stick out again.
- Make sure to press the power button before using the pen.
- If you have a pen display, ensure you have PEN68D, not PEN68. These pen models look identical, but PEN68 won't work with pen displays.
- If you have a pen display, ensure your tablet is manufactured after January 1st, 2017.
