T7610 - Bios reset
How do I reset the bios if I can’t boot , run the bios menu item or run the diagnostics. Booting from the CD ROM, Nic, external usb just does nothing
Every other bios menu item seems to be fine. I.e it recognises all my hardware: ie the correct procs, memory and disks?
Is there anything I can do on the motherboard to re flash the bios?
The front diagnostics panel shows. ‘123’ lights on.

Try clearing the CMOS memory (BIOS). With the PC powered off, open the case and remove the CR2032 coin cell battery located on the motherboard for AT LEAST 10 minutes. Reinstall the battery, observing polarity.
Power on and see if that helps.

Lights 123 is "Some other failure has occurred". Not very helpful. It tends to lead me to a motherboard problem, may not be, but that is my feeling.
For testing, disconnect the data cable to all the hard drives, CD/DVD drives then try to boot and see if the diagnostic lights change or if its able to boot to the BIOS. One possibility according to the manual is a defective peripheral causing the problem.

The change setup menu item takes me to the bios options which detects the hardware and all the data seems fine, but if I choose run onboard diagnostics or bios update nothing happens.

Have you updated the BIOS? There is a BIOS recovery option for some models. I don't know if your model is one that can be recovered or if even possible however the link is below.
Sadly, if a BIOS is the problem (and not recoverable as stated) the fix is to replace the motherboard. The 3 lights as noted indicate a failure but not specific.

There will definitely a bios recovery method. But dell wont tell about it. Ctrl+Esc not worked on Precisition T7610.
