Touchpad stops working intermitently or completely 15-bs013dx

[buffalto]

I have tried removing the device from the device manager and re-adding it.  This has worked in the past but now not at all.

The Synaptics SMBus Touchpad version is 19.5.35.15 I have tried rolling back to last known good version with the same results.

Please help me identify why the touch pad seems to turn off at random times and now seems to be off permanently.

@buffalto,

Thank you for posting your query on HP Community,

Have you tried to run a test on the touchpad from F2?

Have you tried checking with an external mouse? Does the issue persist?

Let's run the test on the touchpad which would be under Component test: 

Mouse/Touchpad Tests - This consists of two tests, the Pointer Test and the Drag and Drop Test.

To run the tests, click Mouse/Touchpad. Select the test you want to run, and then click Run once. Follow the instructions to complete the test.

If the test fails then this would clearly indicate a possible hardware failure with the touchpad. I would recommend you contact our HP support team. 

If the test passes, I would suggest here is to update the BIOS, touchpad and chipset driver on your PC and check if it helps.

You can try updating other drivers on your PC using the HP support assistant.

If the issue still persists after trying out the steps try the steps recommended below.

• On Start , search for Device Manager, and select it from the list of results. Under Mice and other pointing devices, select your touchpad, open it, select the Driver tab, and select Update Driver. If Windows doesn't find a new driver, look for one on the device manufacturer's website and follow their instructions.

• If those steps didn't work, try uninstalling your touchpad driver: open Device Manager, right-click (or press and hold) the touchpad driver, and select Uninstall. Restart your device and Windows will attempt to reinstall the driver.

• If that didn't work, try using the generic driver that comes with Windows. Here's how: in Device Manager, right-click (or press and hold) your touchpad driver > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer, select HID compliant mouse, select Next, and follow the instructions to install it.
