The Dell Inspiron 15 3535 is an affordable everyday laptop powered by the AMD Ryzen 5 7530U processor. A common issue reported by users is a jumpy or erratic mouse pointer — the cursor moves on its own, skips across the screen, or behaves unpredictably when the touchpad is in use.
This guide walks through the most effective fixes for a jumpy mouse pointer on the Dell Inspiron 15 3535.

Why the Mouse Pointer Jumps
- Palm accidentally touching the touchpad while typing
- Outdated or corrupted touchpad driver
- Touchpad sensitivity set too high
- External wireless mouse interference
- Physical damage or contamination on the touchpad surface
Step-by-Step Fixes
Fix 1: Enable Palm Rejection
The most common cause of a jumpy pointer is accidental palm contact on the touchpad while typing. Windows Precision Touchpad includes palm rejection to block this:
- Open Settings > Bluetooth & devices > Touchpad.
- Under Taps, increase the Touchpad sensitivity toward Low sensitivity or enable Turn touchpad off when mouse is connected if you prefer using an external mouse.
- Also look for a Palm check threshold slider and increase it to be more aggressive about rejecting palm touches.

Fix 2: Update the Touchpad Driver
An outdated Synaptics or ELAN touchpad driver can cause erratic pointer behavior:
- Open Device Manager and expand Mice and other pointing devices.
- Right-click the touchpad entry and select Update driver.
- For the best result, visit the Dell Support page with your Service Tag and download the touchpad driver for the Inspiron 15 3535.
- Install and restart, then test pointer movement.
Fix 3: Reduce Touchpad Pointer Speed
A very high pointer speed amplifies small involuntary finger movements, making them appear as jumps:
- Open Settings > Bluetooth & devices > Mouse > Additional mouse settings.
- In the Pointer Options tab, reduce the Pointer speed slider to a moderate position.
- Uncheck Enhance pointer precision and test whether pointer movement becomes more predictable.
“Setting touchpad sensitivity to Low sensitivity in Windows settings stopped the random cursor jumps when I type. My palm was brushing the corner of the touchpad constantly without me noticing.”

Fix 4: Check for Wireless Interference
If using an external wireless mouse alongside the touchpad, RF interference can cause both to produce erratic signals. Unplug the wireless mouse USB dongle, use the touchpad alone, and check whether jumping stops. Keep wireless peripherals and the dongle away from strong RF sources like Wi-Fi routers.
Fix 5: Clean the Touchpad Surface
Oils, moisture, or debris on the touchpad surface can cause false contacts that appear as pointer jumps. Power off the laptop and clean the touchpad with a dry microfiber cloth. If the surface is visibly damaged or has deep scratches over the sensing area, a hardware replacement may be needed.
