Hello there, this is my first interaction with the HP community.
I just bought a HP ENVY x360 13-ag0002na two weeks ago and at first I was very happy with the product, as it is exactly what I needed for my studies. However every once in a while I started facing some problems with the touch screen and the interaction with an active stylus pen, namely:
- When I am writing with the pen (on OneNote, Windows Ink, and similar) the cursor jitters, therefore making it impossible to draw/write anything. This happens even if the pen is standing still on a fixed point on the screen.
- After I touch the screen with my finger (while not using the pen) to drag/zoom/select anything, the input from the pen is not recognized for about 3 seconds: the shortcut button on the top still works, but everything else is ignored, which is pretty annoying for my workflow.
- Often the touch screen is very inaccurate, registering multiple touches all around the screen both when I drag and when I try to click something.
All of these would happen sporadically and (at first inspection) randomly.
Attempted solution 1: Initially my guess was that some drivers were out of date or faulty, so I followed what most answers in this forum to posts about touch screen input and stylus problems suggest, I went to many of the possible HP support pages about the topic, attempted all restarts/driver reinstalling or updating, but I was having no success.
Attempted solution 2: My second guess was that it was the stylus' fault. Since the ENVY does not come with a stylus, I had to buy one (Wacom Bamboo Ink), which I was recommended by another person who purchased the same model as me. I attempted changing the compatibility settings, replacing the battery and/or the nib, but still with no success.
Final note and curious finding: After reading a lot of posts around the internet and doing some testing, I realized that all of the problems only happen when the laptop is charging and the laptop's metal frame is not touching my skin. That is, if while I am using the pen/touch screen with my right hand, I touch any part of the metal frame of my laptop with my left hand, none of the problems presents itself. Or alternatively, if I unplug my laptop from charging, all the problems disappear. I was starting to think the problem was that the stylus was just not compatible and that created instability, but the fact that the stylus works perfectly well when I am touching my laptop, and that the problems involve interaction with the touch screen only as well, discourages that idea. This seems to be some kind of hardware issue, albeit I have no idea what could be causing it.
What could I do to solve the problem? Except for changing the active pen stylus...
Thanks in advance for your time.
