Bugzilla – Bug 6230
"Off" state still drains battery
Last modified: 2008-05-15 13:00:28 UTC
To save battery power, I always turn the JHB off by pressing and holding the home button. This allowed the battery to last several days. But lately when I turn the JHB off I only get 24 hours or so before the battery goes completely dead. It's like the JHB is no longer truly "off" and there's some load that drains the battery even when it's supposed to be "off". I notice this started about when the "Goodbye" power off icon started appearing. I will be able to accurately time how long the battery lasts in a few days as I will be out of town on business.
I think I've seen this as well with recent nightlies/firmwares. I press-and-hold and I get the 'goodbye', followed by the screen going black. However, I'm pretty sure that it's actually stayed on as I ca npress the 'back' button and here the sound you normally get when you press that button. In this situation I've found you have to press-and-hold for the ~20s like you had to in the old days to force a power off. Could you try pressing 'back' or another button that would normally make a sound and see whether it appears the JHB is actually still powered on but the screen is blank?
Caleb: Can you look at this?
I logged a bug about the same problem before PQP2 HW. Ever since PQP2, I have not been able to reproduce this one. Diane: Which hardward is this gentleman using?
This doesn't seem to be a consistent problem for me. It was working OK for me when I tried this morning, and I couldn't reproduce this over several restarts. The firmware was updated last night so I don't know if it's related - I'll keep an eye on it. I'm still not sure this is the same problem as Mark's so I don't want to divert his original report onto my issue accidentally.
Sorry for the delay. With r1061 the unit definitely appears off when I turn it off - I can't wake it up by shaking it. I'll let the battery run down and report back in a day.
I don't know whether that's the same effect as I saw, but I don't remember shaking it was enough to discover it wasn't actually "off". I pressed things like the back button and could hear the normal click/beep noises. I'm pretty sure that shaking it didn't reveal anything.
Mine's definitely off, off, off, no amount of button presses causes any sign of life. Also the LCD screen is completely blank (not even activated pixels without backlight).
FWIW when the JHB is "on" the back warms up. In the "off" state I'm in now, it's stone cold. Still waiting for the battery to run down.
it's possible if the screensaver kicks in that the shutdown is canceled. that's an easy bug to fix, but i'd like to understand if this is contributing to the problem your seeing first. if this is the cause i don't understand why the lcd is not waking up. it would be create if someone could capture the debug from /var/log/message and dmesg in this zombie state.
Approximately 18 hours after I powered it off, I just powered it up again and the battery icon still shows full. (Does r1061 have an accurate battery icon indicator?) I've just turned it off again and I'll keep the bug updated tomorrow. BTW I may turn out to feel awfully sheepish here. I notice there's a ~2 second delay when starting it up where the backlight flashes then everything appears to go dead. But after that the backlight comes on and the Logitech logo eventually appears. I may have interpreted that ~2 second "dead" time as if it was out of power, I never noticed that pause before. Wow would that be embarassing, all this over my interpretation of that pause as it being out of power... Still, that pause "feels" like nothing is happening.
It's now been 51 hours since I first turned it off. I powered it up and the battery reads 2/3. Doesn't seem too bad. I'm going to be busy most of the weekend, but if it powers up on Sunday afternoon with any battery power left that's probably acceptable performance.
Whoops, the comment I made at 2007-12-06 15:52 should have read "30 hours", not 18.
After a busy weekend where I could not test, I turned the JHB on this morning and nothing, the battery is completely drained now. It has been almost 5 days now, that's quite reasonable. Unfortunately I could not determine when the battery did die, obviously it was sometime in between my last comment (at a little more than 2 days) and now (5 days). So, at least for me, the bug is closed.
I've found it to be a lot better recently at actually switching off when it looks like it's off, but just when I thought it must have gone away it happened to me again a couple of days ago. Same symptoms as before: 1. Hold down "standby button" 2. See the "goodbye" screen 3. Let go of the standby button (well before it would have forced a hard shutdown - I did it immediately the goodbye screen disappeared) 4. Screen is off, but unit is otherwise still on. I could spin the wheel and hear the clicks, and press "standby/home" and hear the bleep as it toggled from the home menu to the now playing screen. Unfortunately this was at a time when I couldn't log into the remote (isn't that typical?), so I've been unable to collect the logs from that instance on the device (sorry). However, I'll keep trying and will definitely be able to capture them when it happens again. This isn't necessarily the same problem as Mark originally reported (he's convinced his unit is definitely off as he can't get it to make any clicks from the buttons). Would those in the know prefer me to raise a separate bug to keep things from getting the two confused?
should be fixed in r1124. Would appreciate verification on this one.

Afraid to say that I've just had the "it-look-off-but-it's-on" problem again. I held down the standby button until it played the tune and the screen went off but then noticed that pressing the standby button again didn't turn it back on. I then held the standby button for a few more seconds and it played the "going off" tune again, but again it wouldn't turn on when I pressed the standby button again. I popped it back in the stand and it lit up and is still showing the "goodbye" screen. I've left it in that state in case you want me to do anything else before I hard reset it. I've attached the dmesg and /var/log/message files as requested (the previous two attachments).
Sorry, forgot to mention the jive version. /etc/jive.version contains: 1 r1203 root@padbuild #133 Tue Dec 18 01:22:30 PST 2007
One *final* point (sorry - I should have composed all these better), but before I turned it off the wireless indicator was red, despite it apparently having good coverage because I was able to SSH in. That may or may not be related.
This bug has recently been fixed in the latest release of SqueezeCenter 7.0.1 Please try that version, if you still see the error, then reopen this bug. To download this version, please navigate to: http://www.slimdevices.com/su_downloads.html
