I looked around and didn't find a thread on this, but I'm sure it's probably been asked. The old TIVO I had just stayed on. Is it OK to leave the HR20 on, or should it be powered on and off? Does anyone think it matters?

Thanks for your help. Freddy

It never really turns off, just powers down the outputs and the front panel lights. Someone on the forum checked the wattage and it was something like 45 watts "on" and 39 watts "off". Actually better to turn it off (standby) so it can concentrate on running some of its maintainence programs.

Unless you unplug it, your HR20 is always "on". It goes into a "standby mode" when you "turn it off", but actually stayes powered up anyway. This is so that the unit can promptly kick in to record any scheduled programming.

Some have their units powered up all the time, while others power them down when not in use. Either is fine. More important, in either case, the units are "on".

Does it really do maintenance? I thought that it took care of all then whenever it restarted after a software download.

My understanding that it was an ongoing process; anyone with more details please chime in.

I leave mine "on" all the time - that is, I never use the remote's or the front panel's power button, so my HR20s are never in standby.

Yes it does, but if you don't have the HR20 recording all through the night, it does its maintenance just as well with it "on" as it does in standby. As others noted, the HR20 is never really off. I run mine 24/7 on, always have.

BTW, I got the 0x17E national update last night...came down to my Blue Ring of Death brightly lit up this morning....trusty ol' upgrade detector works again!:)

Let us not forget that "its-not-off-its-in-standby" also applies to our TVs, AVRs, VCRs, DVD players, standard sat receivers, and anything else that is controlled by remote.

It is not really specific to the HR20, and not unusual with today's equipment.

Equipment includes a buncha stuff that I no longer have interest in detailing

Good point, although the power draw in "standby" might not be the same as the HR20, where ON vs. Standby is only a watt or two different.

BTW, my Onkyo HT receiver, when "put in standby"...really shuts down...including all video processing/switching...so it stays on all the time too, and it DEFINITELY draws lots of current when on (with no fan on it, I could cook an egg on top of it).

The HDTV draws just a tiny amount of power...and the large bulb for the DLP is obviously off.

As I think about it, most devices that I have are not like the HR20...the only thing that seems to be powered in these other devices when in "standby" or "off", is the IR processing circuitry to allow it to be turned on (and the backup memory that holds user settings). Very few have nearly full functionality when "off", like the HR20.

As posted above the unit is never really off unless you pull the power cord. Putting it into standby only turns the lights and the outputs off.

I have had 2 of mine since September and never turned them off until about a month ago. Now I turn them off maybe 5 to 10 hours a week. But I have never had a problem.

I know that someone else put a meter on the thing and determined the power draw was about the same but my empirical results suggest otherwise.

I conducted this test some time ago, when the ambient temperature was 70. The DVR is in a closed cabinet with a USB fan.

Unused, in standby, the temp was 111 upon being awoken.
Turned on, hands off the remote for 15 minutes, the temp was 113.
Using trickplay, menus, etc. in a normal way for 15 minutes, the temp was 115.
Put in standby again and left that way for 30 minutes, the temp was 111 after being awoken.

This extra heat has to come from somewhere, it cannot spontaneously appear. It's reasonable to suspect that the DVR is putting out more heat because it is using more power.
Opinions expressed by me are my own and do not necessarily reflect
those of DBSTalk.com, DIRECTV, DISH, The Signal Group, or any other company.

I turn mine off when I am done with it each night.

No idea if that actually helps or not BUT I have had no problems with my HR20 doing this so far.

I tune my HR20 to one of the music channels before turning it off. The theory is that the hard drive won't work as hard because it won't record music channels. Just a theory, I really don't know if it makes any difference.
