I'm facing a frustrating issue with my Lenovo P3 Tower, and I'm hoping someone here can help. System Details:
Model: Lenovo P3 Tower
GPU: NVIDIA T400 4 GB
Current OS: Ubuntu 22.10 (Kinetic Kudu)
The Issue:
I recently got my computer back from a repair center, and they informed me that the drivers were installed correctly. However, I'm now trying to access the BIOS to make some changes, but I can't seem to enter it, no matter how many times I try.
What I've Tried:
Pressing the usual keys (F2, F12, Esc, Del, etc.) repeatedly during startup—I've tried this over 100 times with no success.
Using a different keyboard and switching USB ports.
Attempting to access the BIOS from within Ubuntu using sudo systemctl reboot --firmware-setup.
Disabling Fast Boot and Secure Boot (if they were enabled) via Ubuntu.
The repair center sent me a picture showing that they were able to access the BIOS, so I know it's possible, but I just can't seem to get it to work on my end.
What I Need Help With:
Why might I be unable to access the BIOS even though the repair center could?
Are there any specific tricks or less common methods I can try to enter the BIOS on a Lenovo P3 Tower?
Could this be related to the installed drivers or any other software issue?
Is there a way to reset or force entry into the BIOS using hardware (e.g., a specific jumper or button on the motherboard)?
I’m trying to upgrade (or rather, downgrade) my OS from Ubuntu 22.10 to Ubuntu 22.04 LTS for stability reasons, but I can't do that without accessing the BIOS to boot from a USB drive.
Any advice or suggestions would be greatly appreciated! Thank you in advance.
