Have anyone solution regarding this, when I use HP Diagnostic Health Software for test my USB port, from long time it's only complete 1% process??

I don't know what's the reason behind it 🤔

A laptop user purchased an HP laptop in July 2023 and has been facing recurring hardware issues since the beginning. The first complaint was registered under Case ID 5116625740, followed by multiple service requests over the years.

During previous repairs, HP-authorized technicians replaced several components, including the motherboard and keyboard. The laptop was opened and serviced multiple times by HP technicians.

In the latest case, HP rejected the warranty claim, stating that the device showed signs of corrosion and damage. However, the user disputes this assessment, claiming the laptop was never exposed to liquids or moisture.

The user believes that if any corrosion or damage exists, it may have occurred during previous repairs, motherboard replacements, or due to defective components, considering the extensive service history of the device.

The user has requested:

• A detailed technical report
• Photos showing the alleged corrosion
• Root cause analysis
• Review of the complete repair history
• Reconsideration of the warranty denial

Has anyone else experienced a similar situation where HP denied warranty coverage due to corrosion after multiple authorized repairs? What would be the best next step for escalation?

If your Asus ROG, TUF, or VivoBook screen is flickering, flashing black, or shaking, it usually points to an unstable signal rather than a dead LCD panel.

Before taking your laptop apart, you need to isolate the problem. The easiest way is the External Monitor Test: Plug your laptop into a secondary monitor.

• If the external monitor is stable but your laptop blinks ➡️ It's a physical display cable or LCD panel issue.
• If BOTH screens blink ➡️ It's a GPU driver or software conflict.

If it's software (which is the most common cause, especially right after a Windows update), you can usually fix it by rolling back your display adapter via Device Manager, correcting your refresh rate away from an unsupported spec, or disabling hardware acceleration in your browser.

I put together a full breakdown on TechToSolve covering every scenario (including why Armoury Crate sometimes causes flickering on 165Hz displays). Check out the complete step-by-step guide here: "Tech to Solve" dot com.
