I have an IFR2975 that has been working fine for many years.
It was most recently calibrated a few months ago and the uP board has a new backup battery.
Last month, the soft "Power-down" from the front pannel started to hang at the X-windows screen during a shutdown and I had to turn off the main power.
I have a work-around where I just tell it to reboot and shut off the main power when it gets to the reset screen (display blanks).
So - my question is - has anyone see this and is there a fix?
Also, with all the above, an image of this unit's drive works in another IFR2975, which has no issues with a soft shutdown, so it's NOT the OS.
Thanks for any help here.

Hi bigbop, have you checked the bios settings?

Re: IFR2975 hangs on soft power-down
Yes. This morning I took photos of ALL the BIOS settings in my cloned and working 2975.
I then confirmed the problem unit was set up the same - it was.
I then selected the BIOS to reset to defaults from the EXIT menu and reset all settings to match my cloned 2975, which DOES power down from the front keyboard - so it's not the drive data.
Didn't work - still hangs on the Xwindow screen but the mouse is unresponsive at this point so that O/S process has quit.
I'm suspecting a processor board issue at this point - RAM or NVRAM?
I noticed the bios in this unit is newer and supports booting from a USB device so I may boot up a Linux distro with memory diagnotics to check the processor board - NO Windows though - Mounting the internal VXWorks OS drive on a Windows OS will corrupt it!
