How do you reset BIOS and NVRAM on Dell Precision M6600?
I now have 2x Dell Precision M6600 <Private data removed from public view. DELL-Admin> Workstation laptops that are stuck at the Dell Logo screen with the load bar all the way. You can get it to say "Preparing to enter Setup" with the fans spinning and then off repeating, but it does not go past.
I have removed all RAM (except 1 and I traded that one out with different ones and in different slots), GPU, CMOS battery and so on. I have left the power off of the unit for 7 days, but it still seems to be stuck.
These laptops were fine until we tried to install Debian 12 on it in UEFI. At the end of the install, it said something about NVRAM and it is now stuck at the BIOS boot. I cannot get into the BIOS.
I have searched and I have not found any suggestions about this issue.
EDIT: Both have BIOS A18 and had (no more) the FirePro M6100 GPU.

Trying again, here is what I get...
Removing the battery, the CMOS battery, AC power, and holding power button for 30 seconds does not clear the BIOS/NVRAM.
Removing the battery, the CMOS battery, and then holding the power button while connecting it to AC power seems to wait for 30 seconds before powering on regardless of how long you hold the power button. The system will get stuck at the Dell Logo loading again. You can let off and then press and hold the power again and it will turn off after 10 seconds without doing anything else until you let off and hit the power button again regardless how long you held it to turn it off.
Removing the battery, the CMOS battery, connect AC power, and then press and holding the power button while to wait for 30 seconds before powering on regardless of how long you hold the power button. The system will power on after about 10 seconds and then get stuck at the Dell Logo loading screen again and will not do anything else regardless of how long you hold the power button.
Removing the battery, the CMOS battery, connect AC Power and not pressing and letting the system go through its regular procedure after being plugged in. The system will go through its check and then power itself on after about 10 seconds.

It will not go past to give you the boot option menu to select diagnostics or settings.
Hitting F2 when powering on gets the message "Preparing to enter Setup..." or F12 gets the message "Preparing ont-time boot menu..." with both getting stuck. The only thing that it does from either selection is the two fans will spin up for a minute or so and then turn off for about a minute or so repeating.
