Hi.i just upgraded my bios on dell poweredge t20 and than the power cut because of loadingsheding while the bios was stil busy upgrading ...so now after power is restored the pc comes on but does not show on screen...what to do??
You may start with a flea power drain and check results.
If it doesn't work they try clearing the NVRAM with the RTCRST Reset Jumper.
drain flea power (shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed).After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in, then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.
