BIOS hp probook x360 11 g5 ee 6050a311260-mb-a01

This motherboard is a replacement (donor) board because the original CPU on the old board was dead. However, with this new board, the laptop refuses to trigger and start.

The Symptoms:
  • The battery is completely disconnected.
  • When I plug in the original HP 45W AC adapter, the power/charging LED blinks in a specific sequence: 2 White blinks followed by 1 Short Orange (Amber) blink, and it loops continuously.
  • I have already checked the main power rails (VIN/B+), current sense resistors, and charging IC area for short circuits, and everything seems fine.
  • Hardware CMOS reset did not change the behavior. I suspect the KBC/EC is locked up due to old battery error logs stored in the NVRAM of the BIOS.

Motherboard Details:
  • Laptop Model: HP ProBook x360 11 G5 EE (Education Edition)
  • Motherboard Model: Inventec 6050A3112601-MB-A01

I have desoldered the SPI Flash chip and read the current corrupted/locked firmware. I am attaching the original backup dump to this post.

Could someone please clean the Intel ME region of my original dump or provide a working, clean BIOS file for this specific board?

Thank you in advance for your time and help!
