    HP ENVY 2-in-1 15-fe0053dx Bios/TBT Charges at 5v

    Hey guys I've been working on a HP ENVY 2-in-1 15-fe0053dx that had a dead EC chip. I've replaced the chip but the laptop only pulls 5v at 0.07amps.At this point I believe I need to reflash the Bios and possibly the TBT rom.

    Laptop Name: HP ENVY 2-in-1 15-fe0053dx
    Model : 15-fe0013dx
    Motherboard Model : JPR50 LA-M794P REV 1.0
    Serial : CND32207GZ
    ProdID : 7H9Y3UA#ABA

              No unfortunately it doesn't. I fear at this point I might have another hardware fault I need to track down.

                  Did you flash the EC chip, was it blank or pre-programmed

                      It is a blank chip. I assumed that the laptop would program itself.

                          I don`t know, you would need an EC programmer to read it, if it`s still blank then it would need programming.

                              Cannot modify HP Envy 15 ep-00008na BIOS
                              by Kenzi
                              Hi everyone,

                              I'm trying to modify my BIOS to unlock the advanced menus and unlock the processor power limits. The first thing I have tried is reading the BIOS from the laptop and opening it up in amibcp, and changing the advanced menu to User. However, no matter what tiny change I make to the BIOS, when I flash it back to the laptop with a programmer it says there is corruption and the BIOS needs to be recovered.

                              I've also tried rolling back the BIOS to an older version. I made the mistake of updating to the latest version and now I cannot even edit the CFG and OC...

                              🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
                              by macabook
                              Hello everyone,

                              I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
                              🧩 Initial Issue
                              • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
                              • External display (HDMI) shows
                              ...

                              Bios Request - Dell Precision 5530 2in1 LA-F211P rev 1.0 - updated
                              by mizzed
                              Hi, Would anyone have a bios dump for a Dell Precision 5530 2in1 LA-F211P rev 1.0.

                              Following a failed bios, I had a new bios chip programmed with the the XPS 15 9575 2in1 LA-F211P rev 1.0, which the motherboard has identical model numbers, (having not being able to find a 5530 2in1 bios) however both in bios and os, the Vega graphics, and sound boards are not detected or installable, everything else worked fine. The only difference I can see is that although the motherboards are nearly identical is that they have slightly different CPU/GPU 8705g vs 8706g.

                              If anyone...
