Thanks brother for the help, but with this file the laptop continues showing the TPM error and likewise still has no additional sound, it does not allow exiting manufacturing mode....

Hello everyone, I have this laptop, which is displaying the TPM error, but also has no audio. As far as I understand, this audio damage is related to the BIOS file, so if anyone could help me with this, it would be very much appreciated.

Hi colleague, I appreciate the help, but with this file the laptop won't turn on, only the white charging LED stays on....

Hello everyone, I'm coming to you with this problem. I've performed a measurement on the laptop's charging system, but I can't find any errors. I've already tried using a new battery, and the problem persists. The problem is that the laptop won't charge the battery. Now all I have to do is test the BIOS. I appreciate any help.
