The phrase "bios better" usually implies you are trying to fix a boot issue, a hardware failure, or you want to ensure your system is running the most compatible version of the diagnostic tools.

Here is a comprehensive guide on what HP PC Hardware Diagnostics UEFI is, how to use Version 1610 (or your current version), and how to update it for better compatibility.

Part 3: The HD4 Error Code Fix – A Case Study in "Better"

One of the most notorious issues in HP support forums has been the HD4 error (hard drive not detected intermittently). In older diagnostics, HD4 often triggered a false “Replace Hard Drive” recommendation.

Version 1610 introduces a “SATA Signal Integrity Test.” Instead of just checking the drive’s ability to spin up, it measures the electrical signal quality between the motherboard’s SATA controller and the drive.

In firmware updates accompanying BIOS version 1610 (note: this is distinct—ensure you are running BIOS 01.02.35 or later for full benefit), HP engineers fixed a power sequencing bug that caused HD4 errors on cold boots. Version 1610’s diagnostic now correctly distinguishes between:

  • Failing drive (real failure)
  • Faulty SATA cable/motherboard trace (real failure)
  • BIOS power sequencing glitch (false positive)

Result? Fewer RMA returns of perfectly good hard drives and faster resolution of actual motherboard issues.

Why Version Numbers Matter

A jump to version 1610 is significant. Previous stable builds (like 1520 or 1580) offered basic functionality, but they suffered from slower test times, limited SSD diagnostics, and a lack of cloud integration. Version 1610 closes those gaps entirely.

Step 4: Verify Installation

Restart and press F2 repeatedly. You should see “HP PC Hardware Diagnostics UEFI – Version 1610.0.0.0” at the top of the screen.

5. Error Log Persistence

Failures are written to NVRAM. Even if the system won’t boot, you can access the log on next power-on by pressing F2 → Logs. This is invaluable for intermittent faults.

4. Enhanced SSD Diagnostics with Predictive Failure Logs

While previous diagnostics could read SMART data, Version 1610 goes further. It now reads the telemetry logs from NVMe controllers (especially Samsung and SK Hynix drives). The tool predicts failure not just based on reallocated sectors, but on:

  • Write amplification factor
  • Thermal throttling events
  • Unexpected power loss counts

This predictive layer means you can replace a drive before data loss occurs—a feature older versions lacked entirely.
