Dell Vostro 5640 2-in-1 — Pen Not Working Fix
Reinstall the Dell Touch and Pen Driver Most common fix
Go to Dell Support and search for Vostro 5640 using your service tag. Download the HID Digitizer or Touchscreen driver from the Input section. Uninstall the existing HID touch device in Device Manager, then install the Dell version. Restart and test the pen.
Check Pen Tip and Battery
Replace a worn pen tip using the spare tips included with the pen or from Dell accessories. If the stylus has a battery, charge it fully before testing. An uncharged or dead stylus battery is a common cause of no input.
Calibrate the Touch Digitiser
Search “Calibrate the screen for pen or touch input” in Windows Search. Run the pen calibration. Tapping each crosshair with the pen tip saves a calibration profile that corrects offset or drift.

Quick info
Does touch still work when pen does not?
Yes. Touch input and pen input use separate driver layers. The touch layer usually stays working even when the active pen digitiser driver is broken.
Does the pen work without Bluetooth?
For basic pen input, no Bluetooth pairing is needed. Bluetooth is only required for using the side buttons for eraser or shortcut functions.
Where to find replacement pen tips?
Replacement tips are available from Dell Accessories or from third-party sellers. Microsoft Pen Protocol pen tips from other brands often fit the Dell Active Pen PN557W.
