Windows 10: HP Spectre X360 Convertible KEYBOARD Erratic after upgrade

HP Spectre X360 Convertible (first gen) running on a I5-6200U and Win10Pro-1809 installed. I have tried multiple times to upgrade to newer builds of Windows (most recently 1903 and 1909) and each time, everything appears to be fine, EXCEPT the built-in keyboard is erratic and unusable. (Touchpad works however). Hitting any key on the internal keyboard creates a "keystroke" and I see something happen on the screen, but by the time I release the key it is subsequently erased or interpreted as a control character or Fn key or something strange. It appears to bring up a dialog box or other artifact.
Going back to Build 1809 resolves the problem and the built-in keyboard works fine. On 1809, I see the standard PS/2 Keyboard and the HID Keyboard device drivers loaded.

Any suggestions how I could move forward?

HP Introduces the Spectre x360 Convertible PC

HP today announced the HP Spectre x360, a 13.3 inch convertible PC that delivers an ultra-thin design, the quality customers expect, and performance to get things done.

"Customers are looking for beautiful devices that deliver quality, versatility and portability," said Mike Nash, vice president, portfolio strategy and customer experience, Personal Systems, HP. "The HP Spectre x360 is transformational as it has the productivity of a high end notebook, tablet mode for on the go, tent mode for play and stand mode for watching entertainment in a stunning ultra-thin device."







x360 Design and Experience for Maximum Versatility
The HP Spectre x360 is designed with an all CNC aluminum chassis and is 15.9 millimeters in height and weighs 3.3 pounds. The device features polished metal on the sides that is achieved using a single machined cut, giving it a jewelry-like finish in a natural silver color.

With the HP Spectre x360, customers get an ultra-thin PC with additional versatility to experience multiple modes in one device. Users can transition seamlessly from notebook mode for work, stand mode for viewing entertainment, tent mode for touchscreen entertainment, or tablet mode for on the go. To ensure the display glides smoothly and stays in place where a user wants it, the HP Spectre x360 has innovative new hinges that contain a set of three spiral gears for synchronized and precise movement. The geared hinge design allows the HP Spectre x360 to maintain the same thin profile in tablet mode that it has when closed.

The HP Spectre x360 includes a full-sized, 1.5 millimeter travel keyboard to offer customers a comfortable and familiar experience. The HP Spectre x360 has an extra-wide glass touchpad for improved day-to-day usability.

Premium Quality, No Compromises
To give customers the battery life they expect, the HP Spectre x360 features a 56-watt hour battery that precisely fits into the CNC aluminum body. Next, HP looked at the biggest driver of battery drain -- the high-resolution touch display. The touch panel on the HP Spectre x360 is optically bonded to the display, increasing brightness and pulling each pixel up to the surface of the display. On models with the Quad HD display, the HP Spectre x360 takes advantage of Panel Self Refresh (PSR) technology which holds images on the screen to allow portions of the PC to power down when nothing on-screen is moving. As a result of these and other focus areas, the HP Spectre x360 delivers up to 12.5 hours of battery life.

HP improved Wi-Fi reliability and performance in the HP Spectre x360 for home, work and on the go. Based on issues identified in real-world testing, the wireless driver is tuned to improve performance on noisy networks and across a wide range of wireless access points. The new antenna slot design featured at the top of the display allows for effective 2.4 GHz and 5 GHz tuning, in every mode -- whether in notebook, stand, tent and tablet. The result is wireless throughput and connect rates that outperform other PCs.

Power and Smart Features for Productivity
The HP Spectre x360 supports Intel Core i5 and i7 processors to tackle the most demanding tasks without lag. With a lightning fast SSD up to 512 GB, customers can expect their PC to turn on instantly and load apps quickly.

The HP Spectre x360 supports both a full-size HDMI and DisplayPort 1.2 compatible ports to allow customers to access content across multiple screens. Customers can also take advantage of the built-in Intel Wireless Display technology to stream content on their living room TV. To accommodate multiple devices and accessories, the HP Spectre x360 has three USB 3.0 ports and with HP USB Sleep and Charge, customers can use the HP Spectre x360 to charge their devices on the go even when in sleep mode.

The HP Spectre x360 is expected to be available in the United States on March 1, 2015 at www.hp.com/spectrex360 and Best Buy on March 15, 2015.

HP x360 Spectre Windows Hello No Longer Working

Thanks for the suggestion. For reference (for people coming after me trying to find a solution), the steps Lee is suggesting are as follows:

• Device Security > Security Processor Details > Security Processor Troubleshooting > Clear TPM

Appreciate the help, Lee, but resetting the TPM using the process above didn't work. All it did was make me reset my PIN and sign in again via my Microsoft account. As I mentioned in my initial post, I have an HP Spectre
x360 Convertible 13-ae0xx, so I've been using the drivers found here:

HP Spectre 13-ae000 x360 Convertible PC Software and Driver Downloads | HP® Customer Support

Also as I mentioned, the latest drivers are installed - that's always my first go-to solution (other than turning it off and on again! ).

Any other suggestions?
