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.

Thanks for the suggestion. Unfortunately after removing the battery and power for ~ 0.5h there is no change in the No boot, not being able to launch the diagnostics menu item and not being able to access the update bios menu item. All the other bios functionality seems fine.

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.

If I disconnect the data cables i can still boot into the bios, but the behaviour and lights remain unchanged. Other than I now get an alert, which you would expect, hard drive not found.

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.
