I have just recently notice that, my Surface Pro 3 pen is not working well. This morning, after I have written some notes, it no longer work anymore. But the top button is still working fine. Does it has problem with the battery? But why the top button still work?
Does anyone experience the same thing to me? How to resolve this problem?
The Surface Pen has two separated battery. One for the top button, that it is used for pairing and calling OneNote on Surface. Another for powering the pen itself and your pen might be running out of the battery.
To solve this problem you need to replace the AAAA battery inside the pen. You can buy it from Amazon.
To do this:
Hold the top area of the pen and unscrew it
You will the AAAA battery, remove it
Put the new AAAA battery in
Screw the pen back together
One more thing, this battery is last about 1 year for common use. So if you have used it for over a year then it might be sure that it cause from the pen battery.
