Since a few days some keys of my P6689 don't work anymore. I have to press them very hard and a lot of times until they work again. I already tried removing the driver and reinstalling the driver. What other things can I do to fix this?Best regards,
Considering you've already reinstalled the drivers, have you also tried using compressed air to carefully clean under the keys? If so then I would contact Medion support as it could be a hardware issue.
