Hi ...

Request to my dear computer doctor / tech person:

Thought you might enjoy helping me sleuth this…

Situation: When I’m working with this computer (Dell Inspiron N5110 ) on a hard surface (as I am now), the cursor jumps around while I’m typing. This creates errors. I have to manually move the cursor back where I need it and type again. This is a known issue with this computer : overly sensitive touchpad / body of computer / sensitivity to vibration, etc. with Dell and they are aware of it.

I went online to try to identify solution but haven’t found one yet. The only one I have found that works is to unplug the laptop. One of the sites I found online today states that the issue seems to be moderately addressed when the computer is not fed via A/C power (HUH? What?) Please explain.

Is there a chance that you might be able to help me with this? Meanwhile I will continue searching online. Would you contact Dell?

Hi PLGoss,

Check the status of touch pad in safe mode (restart the computer and tap F8 on dell logo) .Select Safemode and try using the touchpad.

If the touchpad shows the same behavior in safe mode, try updating the Touchpad Driver from the below mentioned link:

Follow the on-screen installation instructions.

I have provided steps below to change the Touch Sensitivity:

Turn on the computer and log into Windows as normal. Open the "Start" menu and click on the option labeled "Control Panel."
Double-click on the icon labeled "Mouse.". The "Mouse Properties" window will open. Navigate to the tab labeled "Device Settings." Click on the button labeled "Settings." A window labeled "Properties" will appear.
Examine the left panel of the "Properties" window and expand the option labeled "Sensitivity." Click on the option labeled "Touch Sensitivity."
Reduce the touch sensitivity setting by moving the slider to the right, towards the "Heavy Touch" label. Experiment with different levels of sensitivity until you find one suited to your needs.
Click on the button labeled "OK" to close the "Properties" window; repeat with the "Mouse" control panel. Your new touchpad sensitivity settings are now saved.

If the issue persists, run full system scan from the below link:
