Pen & pen app not working - Yoga c640

2020-08-22, 7:31 AM

I bought my Yoga c640 right after the lockdown lifted. The problem is that (a) the pen intermittently doesn't connect to the screen (b) the pen app hangs and doesn't connect to the pen at all (c) the buttons on the pen don't work at all.

 

I called customer service, who sent an engineer, replaced the pen, but the new pen has the same problem. I've been calling and writing to customer service repeatedly since then but haven't received a single reply.

I've tried:

  • updating Windows
  • uninstalling and installing the pen app
  • Wacom drivers & HID drivers which are all up to date

 

Has anyone else experienced this problem? Please help!

Hi,

 

As I said above, no the same laptop and probably no the same pen, but I had the same problem: serious intermittent disconnection. There was no noise with the battery shaking the pen; so, I thought It could not be a false electric contact and I tried never the spring solution as mentioned in others forums. However, one day I noted the pen get back the connection if I shake as trying came out the ink. So, I proceeded to insert additional spring from an ink-pen. Unbelievable!!!! No any more interruptions; now, I enjoy the touchscreen ability, specially with software that distinguishes between pen and finger to avoid writing mistake.

 

I really hope you can solve soon your pen problem.
