Touchscreen latency/wake-up issue on HP OmniBook X Flip 14 (Snapdragon X Elite)

[kenn50]

I am experiencing an issue where the touchscreen on my OmniBook X Flip 14 seems to go into a standby or "sleep" mode after a short period of inactivity (often around a minute or so). This happens even while I am actively using the laptop with the keyboard and touchpad.

When I try to use the touchscreen again, it doesn't respond to the first touch. I usually have to tap it once or twice to "wake it up" before it starts registering my input again. It feels as though the touch digitizer is being put into a low-power state too aggressively, leading to a noticeable lag or a "double-tap" requirement to get it working.

What I have observed:

• The device appears to stay in a "Powered On" (D0) state in Device Manager, yet the input itself seems to be gated or paused.

• This is not tied to the system going to sleep; it occurs during active use of the machine.

• The touchscreen is an ELAN2514 device, likely interfaced through the Qualcomm I2C bus.

Troubleshooting attempted so far:

• Checked and adjusted power management settings in Device Manager for the HID and GPIO controllers (where available).

• Attempted various registry overrides for EnhancedPowerManagementEnabled and SelectiveSuspend for the HID/ACPI device paths.

• Tried to adjust "WDF" idle timeout settings to extend the active period.

• Ensured all HP Support Assistant and Windows Updates are installed, including Qualcomm chipset drivers.

• Checked for "AI Presence Sensing" settings that might be disabling input when no face is detected.

None of these steps have resolved the behavior. It seems like a firmware-level power management policy for the I2C bus or the digitizer itself that is not respecting Windows power settings.

Request: Is this a known behavior for the Snapdragon-based OmniBook series? Are there any firmware updates or specific Qualcomm driver configurations that can prevent the touchscreen from entering this inactive state so quickly?

Hi @kenn50,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand you’re experiencing a touchscreen wake-up latency issue on the HP OmniBook X Flip 14 (Snapdragon X Elite), where the first touch doesn’t register after short inactivity. Let’s go through a few checks and explanations to clarify what’s happening and what can be adjusted.

Understand Snapdragon platform power behavior
On Snapdragon X Elite systems, the touchscreen digitizer and I2C bus are managed aggressively for power efficiency.
Even while the system stays in D0 (fully powered), individual input devices may enter a low-power idle state.

Confirm this is not Windows sleep or display power-off
Go to Settings > System > Power & Battery and temporarily set Screen timeout and Sleep to longer values.
This confirms the behavior is independent of system or display sleep, which you’ve already observed.

Check BIOS power and input settings
Restart and enter BIOS using F10.
Under Power Management, look for options related to Modern Standby, Input Power Saving, or Panel Self Refresh, and disable them if present.

Review AI-based power and presence features
In BIOS or HP software, check for Human Presence Detection / AI Presence Sensing.
Even when disabled in Windows, firmware-level presence logic can still gate touch input on ARM systems.

Verify ELAN touchscreen firmware behavior
The ELAN2514 touchscreen on ARM devices uses firmware-controlled idle timers.
These timers are not fully exposed to Windows registry or Device Manager power settings, which explains why overrides had no effect.

Check for optional firmware and driver updates
In Windows Update > Advanced options > Optional updates, look specifically for Firmware or Qualcomm System updates.
These updates sometimes adjust I2C and digitizer idle thresholds without changing driver version numbers.

Test behavior in tablet vs laptop mode
Fold the device into tablet mode and leave it idle for a minute, then test touch input.
If the issue is reduced or absent, it confirms the behavior is tied to laptop-mode power policies.

Perform a full shutdown test
Shut down the device completely (not restart), then power it back on.
Test touchscreen responsiveness before and after short idle periods to rule out session-level power state persistence.

I hope this helps.

Hi, it seems like nothing is working. It is extremely irritating. My bios is very simple and does not have much customization. I do not have a "HP Software" and turning off "allow this device to turn off to save power" for the devices and their parents still did not help. It seems like either a bug with the hardware or a feature since my mom with the exact same computer as me also has this problem.
