Question Encrypted HDD woes on Lenovo G580

[auriga2001in]

Hi,

I have a Lenovo G580, which was password protected both in the bios and the HDD, and running ubuntu 18.04. I replaced the HDD with a SSD and everything seemed OK. I then installed ubuntu 20.04 LTS.
I set the bios and HDD passwords, so I know the passwords.
Now I notice that I am not asked for a bios password. I can live with that, but there are two nagging issues. The earlier HDD was encrypted, and now I cannot use it using a HDD enclosure. It does not get recognized. The second issue is, I can't get into the bios setting by pressing F2 at all. I can get into the OS selection using F12 sometimes, but just cannot get into bios setting. Is this related to the bios password issue as well? Will a bios reset using the coin battery approach help?
Thanks in advance for any help.

Put your HDD back into the laptop to remove the password. Use the occasion when swapping storage to get into BIOS when no storage device is connected.

When I put back the old encrypted drive, I was asked the disk passwd. I could subsequently boot into Ubuntu and reformat the disk to NTFS. BTW, I used a Ubuntu on a pen drive to boot. Later on I restored the laptop with the working SSD drive with Ubuntu. The laptop is functional, but it does not give me any option to get into BIOS.
Earlier, I tried booting without the boot disk, and I could not get into the BIOS using the F2 key... it straightaway went into the boot options, and trying a network boot.
The reason why I need to edit the BIOS options is to remove the network boot option. I think there are some "wake up on" options, that it making the laptop reboot, when I ussue the shutdown command.
Any other options I can try? Or, should I just live with what I have?

If you have an intel Nic in that PC then disable 'Wake on Magic Packet' in the devices properties.
I dont use ubuntu so cant tell you how to do that in their OS.

The problem of the Lenovo G580 not shutting down, was narrowed down to a 4 port USB 3 hub (Orico W9PH4-U3) being plugged in. So I cut open the USB cable to the hub and introduced an on/off switch. Now the PC shuts down gracefully and stays shut.
The original problem of not accessing BIOS settings is not solved.
Thanks.
