Black screen and noise

[QQ38]

My laptop is 14s-dq2000.

I was checking my laptop and pressing lightly on about above of the USB slot, and it got the black screen and noise(not the beeing, like rattle or crack) until I turned off.

Is that RAM on some promble? Hope there's no some power problems. Can I get component diagram form my laptop's specification please.

Hi @QQ38 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for describing what happened so clearly. That sudden black screen and noise after pressing near the USB slot on your HP 14s-dq2000 suggests a hardware sensitivity issue—possibly related to internal connections rather than RAM or power failure.

Here’s how to interpret and address it:

What Might Be Happening

• Flexing the chassis near the USB port may have disturbed a nearby internal connector—such as the display cable, fan header, or even the motherboard itself.
• The noise you heard (not a beep, but a rattle or crack) could be:
  • A fan briefly struggling or misaligned.
  • A loose screw or component shifting under pressure.
• RAM issues typically cause boot failure or blue screens—not sudden blackouts from light pressure.

What You Can Do

1. Run a Hardware Diagnostic

Use HP’s built-in tool to check for hardware faults:

• Power off your laptop.
• Press the power button and immediately tap Esc repeatedly.
• Press F2 to open HP PC Hardware Diagnostics UEFI.
• Run the System Test and Component Tests (especially for memory and fan).

2. Inspect for Loose Connections

If you're comfortable opening the bottom panel:

• Power off and unplug the laptop.
• Remove the bottom cover carefully.
• Check the USB board, fan, and display cable for secure seating.
• Gently press around the USB area to see if anything shifts or clicks.

If not, a technician can help inspect without risking damage.

 

3. Monitor for Recurrence

• If the laptop boots normally and the issue doesn’t repeat, it may have been a one-time flex or contact issue.
• Avoid pressing near the USB slot until it’s inspected.

You can access the component diagram and internal layout for your HP 14s-dq2000 laptop through HP’s official Maintenance and Service Guide. This document includes labeled diagrams, disassembly instructions, and part identification.
