How to fix UEFI Error HWC8010 or HWC8011 on Dell server r750xs POST

2025-04-03

Fixing UEFI Error HWC8010 or HWC8011 on a Dell PowerEdge R750xs during POST typically involves troubleshooting hardware compatibility, firmware settings, or memory/storage issues. Since this is a server-grade system, the steps may differ slightly from consumer PCs. Below is a structured approach to diagnose and resolve the issue.

UEFI Error HWC8010 or HWC8011 on POST

Possible Causes for HWC8010/HWC8011 on Dell R750xs:

  1. Incompatible or Faulty RAM

  2. Incorrect UEFI Boot Settings

  3. Outdated or Corrupted BIOS/UEFI Firmware

  4. Storage Drive Compatibility Issue (NVMe/SATA)

  5. Secure Boot or TPM Configuration Conflict

 

Step-by-Step Fixes:

1. Reset BIOS/UEFI to Defaults

  • Restart the system and enter UEFI/BIOS Setup (usually by pressing F2, F12, DEL, or ESC during boot).

  • Look for an option like "Load Defaults" or "Reset to Factory Settings".

  • Save changes and reboot.

2. Check & Reseat RAM

  • Power off the system and unplug it.

  • Remove RAM sticks and reseat them firmly.

  • Test with one stick at a time to identify faulty RAM.

  • Ensure RAM is compatible with your motherboard (check manufacturer specs).

3. Update BIOS/UEFI Firmware

  • Visit the motherboard/Dell support site and download the latest BIOS.

  • Follow instructions to update (usually via a USB flash drive in BIOS or using a built-in updater).

4. Adjust UEFI Boot Settings

  • Enter BIOS and check:

    • Boot Mode: Set to UEFI (not Legacy/CSM).

    • Secure Boot: Try disabling it temporarily.

    • Fast Boot: Disable if enabled.

5. Check Storage Drives

  • If using NVMe SSD, ensure it’s properly seated.

  • Try booting with only one drive connected.

  • If the drive is new, check if it requires a UEFI driver (some older systems need NVMe support updates).

6. Disable TPM or Clear TPM (if applicable)

  • In BIOS, look for TPM (Trusted Platform Module) settings.

  • Try disabling TPM or clearing its keys (if error persists).

7. Test with Minimal Hardware

  • Disconnect all non-essential devices (extra drives, GPUs, USB devices).

  • Boot with only CPU, 1 RAM stick, and boot drive.

8. Check for Dell-Specific Fixes (if applicable)

  • Some Dell systems may need a BIOS recovery (check Dell’s support site for HWC8010/HWC8011 errors).

  • Try Dell SupportAssist for automated diagnostics.

 

Final Steps if Error Persists

  • Test with a different PSU (if possible).

  • Reset CMOS (remove motherboard battery for 5 mins).

  • Contact Dell/Motherboard Support if the issue remains unresolved.

If the error appeared after a hardware change (e.g., new RAM or SSD), revert to the old configuration to confirm compatibility.
