GT-191 Pen unresponsive
I have the GT-191 tablet that I got back in 2018, I used it for a while then my computer stopped being able to handle it and it's been sitting in my closet in it's box since. I've got a much better computer now and took it out to get it set up again, I've downloaded the drivers properly, it's connected and displays as expected, but the pens are completely unresponsive on the tablet. The LED charging indicators come on so they're not completely broken.
I no longer have the original chargers so have been trying to use an old direct to power charger I found that fits properly and makes the charging indicator turn on. I suspect it may just not be the right voltage and ordered a new cord but I can't verify that's the issue until it arrives in the mail.
I've done all the typical solutions; restarting my computer, uninstalling and reinstalling the drivers without the tablet connected to the computer, tried with and without the driver installed, toggled windows ink. The pen will not move the cursor or respond to button use.
Is there anything else I can try before the replacement charging cord arrives? Are the pens just dead from lack of use?
