usb ports and touchscreen are not working

[shashank3012]

hi my notebooks usb ports are not working and also the touchscreen display is not responding when i try to use the touch screen 

in the device manager under the usb controllerwhen i open it i see this kinda message 

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

kindly help me out of this

@shashank3012 Welcome to HP Forums Community!

Here's what you need to do to deal with the touchscreen issue before we deal with the USB, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction and you'll need to Contact HP to have it repaired.
• And does the mouse work fine? it doesn't go around randomly clicking things, does it?
  perhaps check with an alternate mouse to rule that out as well?

While you respond to that, I have a few more steps that should help:

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the Touchscreen isn't appearing on the diagnostics, it could again, determine a hardware failure,

If it works on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here

1. as you have suggested me to update my bios and chipset drivers and i have done that . and i found no change 

2. thereafter i have tried to check whether is it hardware malfunction or software problem in the bios menu i the touch screen was functioning perfectly . here after this i came to a conclusion that it is software problem 

3. thereafter as per your suggestion i tried to  reinstall windows using the recovery partition 

thereafter the installation of windows was successful 

as on 03/07/2019 at 22:00 hours as per IST

@shashank3012,

I'm glad to hear you got it working however, it seems that the issue has reoccurred again. 

In this scenario, I would suggest here is to update the drivers either using Windows update or using HP Support Assistant. 

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

Keep me posted how it goes

Thank you and have a wonderful weekend 🙂

hi @jeet_singh

i have done everything the same way as you have suggested 

and i dont see any change in my touch screen display or usb ports or bluetooth they are neither responding properly

[Jeet_singh]

Let's try to perform a system reset on the PC.

You may follow the steps suggested in this support document for  - HP PCs - Resetting Your Computer (Windows 10)

For some reason, if this does not help then I would suggest you could try to use HP Cloud Recovery Tool which allows you to download recovery software to a USB drive.

If this option does not work then you can follow this link: HP PCs - Obtaining PC Recovery USB Drives or Discs Or else you may contact our HP support team to help you order a set of recovery media for your PC.

HP support team can be reached on this link. 

Keep me posted for further assistance!

Cheers 🙂
