Have you tried to "Calibrate the screen for pen or touch input" in Windows? Just search that in the Windows Start Menu and hit "Calibrate."
Have you tried to update the Bios?
In the meantime, let's try these steps here:
The pen can be in two modes: tablet mode (for drawing etc), and presentation mode (for pointing and switching slides). You switch between the two modes by holding the side (thumb) button down and clicking the top (eraser) button.
When the pen is in presentation mode, click the eraser button to make the slides go forward, double click to make the slides go backward. Single click on the thumb button is a regular left click, double click on thumb button is a regular right click.
You can find more instructions:
First off, you must have your pens Bluetooth mode turned on to go into Presentation Mode.
If you click your eraser (grenade) button once and the LED on the side flashes green once, then you're in "Active Mode". In active mode you'll get much longer battery life between charges, with about 10-15 days of daily 8-hour use in my findings. BUT the pen's bluetooth is turned off; disabling the tilt, Windows Ink shortcuts, and flip to erase features.
If you then hold the eraser button for about 5 seconds and release, your pen will switch to "Bluetooth Mode". While in bluetooth mode drawing with tilt, Windows Ink shortcuts, and flip to erase features will all work and your LED will constantly blink blue. BUT you're only gonna get 1-2 days of battery life from a full charge.
So now if you're in Bluetooth Mode and paired, while holding the side button on your pen, click and release the eraser button.
Congratulations, you're now in Presentation Mode. Just point your pen at your screen from a distance, and look... you're a wizard Hairy!
The pen uses internal accelerometers to move the cursor, much like a Roku remote, or lesser so a WiiMote. And although it isn't terribly too accurate, it works wonderfully for presentations or TV casting of photos or games.
Presentation Mode Controls:
Click the side button for a regular left click.
Click and hold the side button is a left click and hold, such as dragging, scrolling, or selecting text.
Double clicking the side button is a right click.
Clicking the eraser button is a Page Down.
Double clicking the eraser is a Page Up.
Holding the eraser button for 5 seconds turns off presentation mode.
Hope this answers your question.
Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
