Hi,

Try the following.

First, download the Synaptics driver on the link below and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp72001-72500/sp72142.exe

When done, turn off your wireless card ( should be f12 ).

Open windows control panel, open Programs and Features, right click the current Synaptics driver and select Uninstall.

When complete, restart the notebook.

When windows has reloaded, open your Downloads folder and run the Synaptics installer - when this has completed, restart the notebook again.

If this has corrected the scrolling issue, turn your wireless card back on and use the utility on the following link to prevent Windows 10 from automatically updating the Synaptics driver.

I have tried that one also,butpointer freezes frequently.Once a key input is given it become movable.Am I need to modify any changes in synaptics smart sense option?

Hi,

Try the same procedure to install the Synaptics driver below.

Synaptics Driver Version 17.0.18.8

When done, open the Synaptics settings panel, disable SmartSense and then check if the touchpad will now work with a keyboard key held down.

Sorry to say this Sir,Still the problem exist.But the time interval taken was too lokk,also I felt it wasnot observed when keyboard is using.Is there any connectio with keyboard and touch pad properties.Auto scrolling is irritating

Hi,

If your using the 17 series Synaptics driver and have disabled SmartSense, this usually corrects the problem - the only other suggestion I Have is to check the following.

In the Synaptics Control Panel, make sure that for both 'Two-finger Scrolling' & 'Scrolling' that the option 'Enable Coasting' is not checked.

From the Start Menu, select Settings, select Devices, the select Mouse & touchpad - set 'Scroll inactive windows when I hover over them' to Off and also set the Touchpad to No delay (always on).

Freezinng problem seems to be ok with your suggestios.Thank you sir,but the scrollling occurs rarely.

My doubt is whenever I press a key after scrolling occurs,then it become normal state.Why that become to normal state when keystroke given?Is desktop refresh after the keystroke given?

Even after I uninstall the synaptics driver auto scrolling problem is still there.Willthere be any problem with windows update?Or it caused by any malicious software?Im using windows defender only,nothing detected? Will a clean reinstllation of windows by formatting all my drives help me?

Even I reset the PC by completely removes the files and retaining windows 10,the auto scrolling still continues? why that?
