A couple of days ago, I had a dead motherboard for a HP Z420 wich I sent into RMA and got another one. The new motherboard booted fine but I got the following BIOS message:
Management platform (ME) in manufacturing mode
At first glance there are no other symptoms but after digging a bit, it keeps me from pushing Bios configuration settings automatically in windows using a config file wich I can do fine on all other machines. I have to configure the Bios manually. Also I found out that if I move the FDO jumper on the motherboard to flash the management engine hoping to fix this, I get the following error message:
error - global valid is not set, please power cycle the system.
I tried calling HP support, a technician even came on site to check it and he was not able to fix this.
2 days later, received another RMA motherboard for another Z420 (different PC) and the bios is also in this manufacturing mode. Anyone knows how to fix this?
