I haven't been using my idsd micro lately for over 2 month and i think i faced the problem with the over discharge and flat battery, it didn't want to charge, i read about the issue didn't understand the procedure quite well, so i left it charging for 24 hours with no luck .. then i read more into the subject and found more detailed procedure by ifi that worked for me, i wanted to mention it here so if anyone had the same problem.

while charging a flat battery it will be blinking blue, it should only take around 60 minutes to turn to steady blue and start charging normally, if 60 minutes passed and it is still blinking blue, you should remove the usb cable, wait for 30 seconds then connect it back and leave it charging again for 60 minutes, if still didn't turn to steady blue, you should repeat the procedure as needed until the led turns to steady blue, it can take up to 5 cycles to work, if more than that the battery can be dead.

i had to repeat the procedures 3 times and on the fourth time, it turned steady blue and started charging normally.

i have a question though, if i am going to shelve it for a long time, is there some procedure to avoid this because i read it harms the battery, or should i just recharge it once every month or so ?

If it gets discharged once in a while, that's not very harmful, no worries.

Just ordered one of these the other day, but having trouble sifting through the comments on what the ideal USB connection for PC is. The package states it has a few usb female adapters. im mostly wondering between using USB A and B, and USB 2.0/3.0. All help appreciated!

A cable is included in the box.

Adapters are included in case you want to use a diferent cable.

Is there a tool. available which browses my music library and tells me which albums are available on MQA format?
This is possible with MediaMonkey.

Just downloaded the free version .... how do I do that searching for MQA albums?
Right-click on the column headings and add a column for 'Extension'. Then click that heading to sort on it.

Yes, understood, but my question was which connection was “ideal” or “recommended” between the cables that are included.
The supplied USB cable hooked up to PC works great! I haven't ever tried a direct comparison between it and optical, but USB sounds great either way.

I tried Eitr into the optical and it sounded better than USB in. That of course reduces the portability however. The iPurifier gives a sonic benefit over USB but it nukes my computer battery (2x faster burn rate) so I don’t use it if running fully off battery.

We're very happy how this one turned out, but since it's active, it has to take some juice off your machine.

Yeah fully expected, any active dongle accessory can drain the internal laptop battery.

I should also mention that the iSilencer works well too and doesn't drain my battery appreciably. It can be used with an iPhone using the camera connection kit without drawing too much power for the phone.

However the iPurifier creates a much quieter background and an provides more instrument separation. It's a great compact solution that I use when I have access to a power outlet.
