I have SDR running and the 6400M display is turned off (black). I have no idea how I did that. Anybody?

do you have hdml connected?

2 things i have found that cause this

1. the power button is a relay that turns on the tablet and the radio. you can actuly power down the radio and keep the tablet on if you hit the power button while the tablet is booting. this will now cause the switch to be out of sync, now when press the power button to turn everything off, it will not power back on the tablet the next time until you turn off the power supply to the radio.
2. if you have hdml connected to the radio. it looks that windows does not shut the tablet down correctly so the next time you power on the radio the tablet never restarts because its actually never shut down. its just hung. but your radio will work fine with smartsdr. if you use hdmi you need to turn off your power supply after you turn off the radio. this completely shust down the tablet so that it will all turn on correctly the next time you sit down at your radio
