I don't understand why did you use my entry as a quote for this message of yours.
Er, because you're the one advocating this procedure.
Peter
Oh, I see! You haven't seen this line then,
"I said nothing about supercaps. I only said that this method works for most time. And it still does."

Because you were complaining about this methods "effectiveness" on supercaps. But that line was my direct answer to your implys.

Let me repeat it again,
"I said nothing about supercaps. I only said that this method works for most time. And it still does."

Oh, wait. Let me remind you your words:
"if you could really drain the supercap via those pins, the supercap would try and recharge an empty-ish battery, which is clearly the Wrong Thing"

And I am answering:
"I said nothing about supercaps. I only said that this method works for most time. And it still does."

Oh god... I said something too!

"I don't think trekstor vibez has any supercaps inside. There are more easier ways to put system on somekind of a steady standby period especially for a system fed with micro amperes and a few volts."

I sense a misunderstanding here.

Blackozan, peter worked at Sigmatel while the vibez was being developed and probably knows the vibez better than most of us ever will.

Defector works at TrekStor now and is such a person in a position to get real answers.

Make sense?

I'm not arguing about knowledge here... There is a misunderstanding as if I've claimed anything about any supercaps. Thats ridiculous. Aren't we all writing and reading in the same language here?

Of course anyone worked at Trekstor would know better about circuitry of this device. But there is one thing solid: "If your Vibez is frozen, and seems death, try my advice. It might get better" (and very faster than waiting to get somethings change with battery seperated)

Yes. I, for one, would like defector's input on the matter.

blackozan, I don't think Peter (or anyone else) is under the illusion that you introduced the usage of the word "supercaps." He was making a logical assumption, based on his understanding of the Vibez' architecture, that the procedure you're describing involves the player's built-in supercap in some way. He was adding to your information, not claiming you said something you didn't.

That's exactly how I read it, too.

That's what you said. And peter just warned that this procedure *might* be dangerous in his eyes, due to the way the Vibez is designed, and asked for further input from the Vibez' hardware architects.

Seriously, I don't see how you got the impression that peter said you would be saying anything about "supercaps" or the Vibez' architecture - he was the one introducing the word - and I would be grateful if someone told me I was doing something potentially harmful to my player without knowledge.

I's suggest to wait until some with deeper knowledge of the Vibez' electronic architecture speaks up, I guess there's not much point in discussing this topic any further before...

Thanks for your warning, peter! (Furtunetaly, my Vibez doesn't suffer from crashes or "sudden death issues" so far...)

Greetings,

Peace and love dudes (and dudesses).  :scared:

I'll ask the designer of the vibez PCB and get the definitive answer.  :-)

Great, thanks! Perhaps you can ask him about the whole issue, too, and whether there will be some kind of fix or if at least new vibezes won't have that problem anymore.

Ok. I didn't manage to get an opinion on the whole issue but he did say that short-circuiting those pins is not a good idea as it will shorten the life of the capacitors in the vibez.

This really starts to piss me off. I just almost blew my right ear out. All of a sudden the right channel turned into a very loud, very high hissing or more like screeching noise. I pulled the earplug out as fast as I could but my right ear still hurts, ten minutes after. Perhaps I should move to the US, then I could at least sue Trekstor when I become deaf the next time this happens with a podcast that requires a higher volume level.

With the plugs out of my ears I experimented a bit: The screeching stopped as soon as the playback stopped. I restarted the Vibez and noticed that the beeping sounds during the "power on protection" didn't cause the noise but hitting play again did. The usual opening up, taking the battery out, waiting a while and putting everything back together fixed the issue. For now.

Until this damn issue is finally fixed by Trekstor I recommend not turning the volume much above 10 (with headphones at least) and using a software normalizer on the files that are too quiet. Just in case.

Couple minutes the first time. Turned it back on and it was at the music screen. Went back to radio, went out in less then a minute. Shut off again later playing music, screen just faded out.
Not looking good for mine, I'm afraid.

For mine I'm under the impression that it comes in waves. Might just be statistics and psychology though. Twice a day is not much compared to what mine did at high times. OTOH the last two weeks or so it hardly shut down at all.
