Integrated Camera Not Working

Subject: HP Built-in Camera Error 0xA00F4244 - Hardware tests pass, but fails in Windows

The Problem: Whenever I try to use my built-in HP Wide Vision HD Camera, the camera indicator light turns on for a brief second, then immediately turns off. The Windows Camera app throws the exact error code: 0xA00F4244 <NoCamerasAreAttached>.

Additionally, the camera completely disappears from the Device Manager (it is not even visible under "View Hidden Devices").

The Big Clue (Hardware Test): I ran the HP PC Hardware Diagnostics UEFI tool before booting into Windows. The Web Camera component test PASSED perfectly and displayed a live video feed on the screen. This proves the physical camera module and the ribbon cable are fully functional. The camera only crashes/disconnects the moment Windows takes control of the system.

Troubleshooting Steps I Have Already Tried (None of these worked): I have done extensive software and power-state troubleshooting, but the camera still refuses to work:

• Privacy Checks: Verified no physical kill switches are active and Windows Privacy settings are set to allow camera access.

• Driver Swaps: Uninstalled the OEM driver and forced Windows to use the generic Microsoft USB Video Device driver.

• Hard Reset / Flea Power Drain: Turned off the laptop, unplugged everything, and held the power button for 40 seconds. (This temporarily made the camera reappear in Device Manager, but it immediately crashed again when trying to open the video feed).

• Power Management: Disabled "USB Selective Suspend" in Power Options, and unchecked "Allow the computer to turn off this device to save power" for all USB Root Hubs in Device Manager.

• Registry Fix: Added the EnableFrameServerMode (set to 0) in the Windows Media Foundation registry keys.

• BIOS Update: Flashed the absolute latest BIOS firmware available for my exact HP serial number to fix any ACPI/USB handoff issues.

• OS Rebuild: I performed a full Windows 11 In-Place Upgrade (Repair Install) using the official Microsoft ISO to completely rewrite the core Windows OS, PnP subsystem, and driver cache.

My Questions: Since the camera flawlessly passes the pre-boot UEFI diagnostics but completely drops off the internal USB bus even after a fresh Windows In-Place Repair Install:

1. Is this a deep Windows 11 PnP/driver incompatibility?

2. Could this be a degraded motherboard USB header/power regulator that survives the low-power UEFI state but crashes under the ACPI power load of a full OS?

3. What is the definitive fix for this, or is a physical motherboard replacement/external webcam my only remaining option?

System Model Victus by HP Gaming Laptop 15-fa1xxx is my Laptop Model , I also tried Windows Support they Clearly mentioned it is the manufacturer Driver Issue.

Also Have tried uninstalling and Reinstalling the Drivers as well , still no solution as well.

Hi @ak04102002,

Welcome to the HP Support Community!

Thanks for reaching out!

You’ve done an excellent job narrowing this down, since the HP Wide Vision HD Camera passes UEFI diagnostics but fails once Windows takes control, the hardware itself is fine. That rules out a ribbon cable or sensor fault. The fact that it disappears from Device Manager after Windows loads points to a driver/firmware handoff issue between Windows 11 and HP’s camera module.

Manually Install the HP Driver

1. Go to the official HP Customer Support - Software and Driver Downloads website.
2. Enter your laptop's exact serial number to ensure you get the exact match for your specific hardware revision.
3. If Windows 11 drivers are not listed, select Windows 10 from the operating system dropdown menu.
4. Expand the Camera or Driver-Keyboard, Mouse, and Input Devices section.
5. Download the standalone camera driver installer executable (usually an .exe file).
6. Right-click the downloaded file, select Run as administrator, and follow the prompts.

Run the HP UEFI Hardware Diagnostics Webcam Connection Test again and note if the camera stays visible after reboot. If it vanishes, firmware corruption is likely.

If none of this helps, it likely needs a service.

Let me know how it goes

Take care and have an amazing day ahead! 🚀
