Facing a hardware problem (HP Laptop reboots without any dump)

[anandnathaniel]

Hello Tech Experts,

I've a HP Spectre x360 - 13t-ap000 CTO (Product number: 4CJ14AV). And whenever I connect a USB disk on the USB A port, or to the USB-C port, the OS hangs with a blue screen and reboots without a dump file. I'm not able to identify the causes of this problem.

I've performed hardware diagnostics; it completes successfully without any errors or warnings. Do you think whether there could be a short circuit inside the motherboard.

Please assist with any recommendations to identify this unique problem.

Thank you, Anand

Hi @anandnathaniel,

Welcome to the HP Support Community!

Thanks for reaching out!

I understand that your HP Spectre x360 - 13t-ap000 CTO reboots with a blue screen whenever you connect a USB device, and no dump file is generated. You’ve already run hardware diagnostics with no errors, but the issue persists, and you’re concerned it could be a motherboard short circuit. Let’s try narrowing this down:

Update BIOS & Drivers

Go to the HP Support website, enter your product number, and install the latest BIOS, chipset, and USB controller drivers.

Outdated firmware can cause USB-related crashes.

Test with Different Devices & Ports

Try multiple USB drives or peripherals.

If the crash happens with all devices, it points to a port/controller issue. If it only happens with one device, the device itself may be faulty.

Check Event Viewer & Reliability Monitor

Press Win + R → eventvwr.msc → check under Windows Logs → System for any USB or hardware-related errors.

Also open Reliability Monitor (search in Start Menu) for clues on critical events before the crash.

Disable Fast Startup & USB Selective Suspend

Go to Control Panel → Power Options → Advanced Settings and turn off USB selective suspend.

In Power Options → Choose what power buttons do, disable Fast Startup.

Restart and test again.

Run System File Check & Memory Test

Run sfc /scannow in Command Prompt (Admin).

Also run Windows Memory Diagnostic to ensure RAM errors aren’t causing instability.

I hope this helps.
