Request: Lenovo ThinkPad T15p Gen 1 – Phoenix SecureCore BIOS Unlock (Advanced/Power Menus)

Hi all,

I’m trying to unlock the advanced BIOS settings on my Lenovo ThinkPad T15p Gen 1, which uses a Phoenix SecureCore BIOS. I’d like access to menus such as Advanced, Power, Thermal Configuration, and CPU Voltage Control for undervolting and power tuning.

System Info

  • Model: Lenovo ThinkPad T15p Gen 1
  • BIOS Vendor: Phoenix SecureCore
  • BIOS Version: N30ET57W (1.40)
  • BIOS Date: 2024-07-16
  • Chipset: Intel WM490
  • Dumped via: flashrom on Linux (no hardware flasher yet)
  • File Size: 32MB

What I’m Hoping to Unlock

  • Undervolting options (e.g. IA AC/DC loadline, voltage offset)
  • CPU power limit settings (PL1, PL2, Tau)
  • Fan curve or thermal trip point tuning
  • Any available debug, chipset, or hidden engineering menus

I haven’t flashed anything yet. I understand that unlocking may require disabling BIOS Lock, FPRR, or flashing externally. I’m comfortable using a CH341A + SOIC8 clip if needed.

Thanks in advance for your help!
