What is its cost? Will it solve the problem I have?

• Laptop powers on and boots into Windows normally.
• System operates correctly while running.
• After performing a restart, the laptop shuts down but fails to power back on.
• The system can be revived by disconnecting the battery or performing a power drain (holding the power button for ~30 seconds).
• Service Tag disappears intermittently after battery disconnection.
• TPM device is not detected.
• BIOS was updated successfully to version 1.41.0, but the issue remains.
• 3VALW and 5VALW rails are present during the failure state.
• VCORE is present (~0.861V) when the system starts normally, but absent when the no-power condition occurs.
• The EC responds to the power button (charging LED flashes briefly), but the system does not complete the power-on sequence.

Why are there so many problems? Where did you copy this information and what do you want me to read it for??

Sorry, I was only providing information about the Dell laptop I currently have in my workshop. Since I was informed that the TPM fix is a paid service, I shared the details of the issue to determine whether fixing the TPM could also resolve the problem I am experiencing with the laptop.

Thank you.

Just to confirm, is the TPM patch related to the restart/no power issue, or will it only fix the TPM error?

only remove TPM,
All other problems need to be fixed first, there may also be other problems unrelated to the bios
