    Maybe this should be a poll question. I have seen several scattered comments about leaving the 921 on versus turining it off. Are there compelling reasons for either argument?

    Some of the issues are fans running constantly and dirt and leaving the hard drive running. I never turn my PC off but use Windows power mangement to shut the off the monitor and hard disks when idle. Would this have more than do with saving power than wear and tear on the hard drive? I would think some of the same reasons you would or would not turn off your PC drives would apply to the 921 as well.

    I just want to do the right thing to prolong my 921's longevity.

    Would anybody like to comment on the issue?

    The only compelling reason to "turn off" your 921 (really just putting it into standby, as the fans and hard drive always runs) is that the 921 will only auto-reboot each night if it's in standby. I usually put mine into standby when I head for bed.

    Hmmm interesting. I usually don't since the wife likes to fall asleep with the TV on. Maybe that is why I am having the issues I am having. It is not auto-rebooting every night.

    Is it hardcoded to midnight by any chance ?
    If so, it would never happen for me, since I have timers recording at that time on most days, and I am most likely home using it anyway at that time.

    Supposedly the witching hour is 2:00AM if no timers are set to fire at that time.

    It is supposed to try multiple times during the night to miss any timers. I'm pretty sure it tries on the hour starting at either 1am or 2am.

    I guess then it's better to put it in standby so that it does do it's nightly reboot.

    Does the motherboard have a battery that keeps the clock running like a PC?

    How do you know if the auto re-boot occurred?

    As for the hard drive, by putting the unit in standby you save it from constantly writing to the buffer. (Debate over always spinning vs repeated power-ups intentionally ignored.)

    I Never turn off either my PC or my 921 or my TV. All are on a UPS.
    My PC has been running 24/7 for 5 years. The only time it gets a reboot is after installing software.
    Before I upgraded to HD last year I had a JVC 27" that ran 24/7 for 8 years.
    My 921 gets a reboot about every 2 or 3 weeks when something stops working or stops responding.
    As for the 921 noise, either mine doesn't make as much noise as others or my hearing is getting bad.
    In my earlier days I was an engineer for a television station. We had automation equipment with hard drives as well as video monitors that had run 24/7 in excess of 11 years.
    With now over 35 years in the industry I am a firm believer in "always on".
    Thermal cycling has killed more of my equipment than MTBF.
    Of course this is just my opinion - I could be wrong !!

    Mark, is this a different kind of reboot than a power switch or a power cord reboot? I think is this is the one that restores my system in the middle of the night if I get a "lost lock".

    It should be equivalent to the power switch ("soft") reboot.

    As for how to tell if it happened, move your PiP window position away from the bottom right corner. If it returns to bottom right, the box rebooted. :)
