Cursor jumping, scrolling freezes, clicking an option not working sometimes

[SM_Fahim]

I'm facing several problems at a time.

1. After writing a text, if I try to delete a character or a word, when I press backspace, one character deletes but the cursor goes to the start of the line. If I then try to click at the end of the text, the cursor again jumps back to the start of the line. Only using keyboard I can get back to the end of the text. But again, I can't delete more than one character. If I try to select the whole text by double click, it highlights the text for less than a second and then again gets unselected. So I again can't delete a whole text.

2. Sometimes and not always, while I'm trying to scroll a page, it scrolls a little bit and then again goes back to the top of the page. This problem shows for some time and then suddenly gets fixed. But after a while, the problem again shows up.

3. While I'm trying to click an option, sometimes it doesn't click that option. Like, after having the 1st problem, I was trying to adjust the cursor speed, but it suddenly selected the minimum automatically and couldn't be selected to any other value. I had to restart my PC to solve this for a while. But when I'm trying to select an update option from HP Support Assistant, it couldn't be selected. 

I was trying to go for the Hardware and Devices Troubleshooter, but I encountered that there wasn't an option for this in the troubleshooting option. I searched online, found others having the same problem, and none of them find any solution.

I suggest you reinstall the Touchpad driver from Device Manager

- Select the Start  button, type Device Manager, and select it from the list of results.
- Look for Mice and other pointing devices and expand the List
- Look for Touchpad driver then right-click it, and select Update Driver.
- Select Search automatically for updated driver software.
- If these steps don't work, try reinstalling the driver: Open Device Manager, right-click the Touchpad driver and select Uninstall. Restart your Notebook and Windows will attempt to reinstall the driver.
 

Also update the BIOS from this Link: https://support.hp.com/us-en/drivers

You can also run a Touchpad Test from F2 Diagnostic to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the Notebook.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Touchpad

Keep me posted how it goes 😊
