Similar story happened to me last month - left on for 4  days in a drawer. It never did re-charge. Hope that you have better luck.

 
Wow.... this is really scary. Did the red light go on too? Did you try to turn it off and connect to some USB power supply to recharge the internal battery? It may take a few hours or so to do it and the unit should power on after the battery has some juice in it. Complete charge can be 24-48 hrs depending on the supply.
 
I think it should not be the case with the unit turning into a brick if left powered on and unplugged for a few days or even months. The internal battery is drained and, if I understand correctly, the unit shuts down if the battery voltage is too low and it needs the battery to run even when plugged in. But why it would not recharge after the battery is drained???? Does the battery get drained completely and cannot be recharged again, like Li-Po type batteries? I read that the internal circuit in iDSD Micro has a voltage drop prevention mechanism that shuts off the battery to prevent the complete discharge, is it not true?
 
iFi Team - please chime in to shed some light on that. Is there a possible hardware or software bug that prevents the battery to pick up the charge? I am now afraid to leave my unit unplugged when going out of town for a few days or something like that.
 
Once the similar thing happened to me too before I got the iUSB power supply. I listened to the music the night before in battery mode and did not charge it over night, then listened to iDSD all day long while working, then around 4 it shuts down by itself. I turned it off, turn it on while connected to my USB laptop port, but it will not power on, the blue light goes on followed by the red light. I got scared that my iDSD went bad or something. Then I just left it alone for like 30-45 minutes, tried again and it powered on. I kept on listening to the music in USB-powered mode and later it took quite a bit to recharge, the blue light is on then off.
 
Hopefully it helps and nothing is wrong with your iDSD, just needs some charge maybe?

Also, make sure the mode switch is set to ECO so it will only draw power from the USB port. 
 

 
Just curious.... Is that in the manual? I understand that it draws the power from the USB port when turned on AFTER plugged it into the USB port. When turned on BEFORE plugging into the port, it runs on internal battery instead of using the power from the USB 5V current.
 
I do not know if ECO/Normal/Turbo switch has anything to do with the power mode, it only affects the wattage from the headphone amplifier.

What is an iUSB power supply?
 
I have been connecting the iDSD to my work laptop with the supplied blue USB cable.
 
Is there a different/better charger I should be using?

MusicDirect.com sells it for $229 and $199 sometimes.
 
iDSD can be re-charged from any laptop using the supplied blue cable. It works great in USB mode too in terms of sound quality but still sounds better in battery mode depending on how clean your USB power is, some people reported different audio quality with different machines. However, for the best quality I would recommend iUSB which supplies very clean USB power to iDSD and it can operate 24/7 without the battery being drained, etc.

Interesting! I want one...
 
What are the cable connections for a laptop with the audio files and JRiver, the iDSD, and an iUSB. Is there a diagram somewhere? None of the manuals on their site seems to show how to hook it up.

Pretty simple, no need for the diagram. There are plenty of discussions and diagrams online anyways.
 
1 - Laptop connects to iUSB with the USB cable.
2 - iUSB connects to iDSD with the USB cable (using the data/power USB output of iUSB). 
3 - Plug the iUSB into the wall electric outlet using the included 9V adapter.
4 - Enjoy the music.

Same question here, so there is no way to baypass the battery in normal and turbo mode?

Normal and turbo modes only affect the volume of the amplifier output in iDSD, they have nothing to do with bypassing the battery. Turbo mode will deplete the internal battery faster than normal or eco modes. To power the iDSD from the internal battery - simply turn on the iDSD then plug in the USB cable. This way the battery can be 'bypassed', however, it is still needed somehow for iDSD to work. Completely or almost completely discharged battery prevents iDSD from even powering on with the USB cable connected or not. Hope that helps.

i just love my ifi dsd micro, really its amazing, nothing bad to say about it
 
thanks so much ifi, u r truely innovators, and i hope u keep up this policy in making it possible to own great devices at reasonable prices and do not venture into insane pricing like other companies do
 
i sold my chord hugo and no regrets whatsoever on the opposite i am more happy with ifi micro dsd than i was with chord hugo

Normal and turbo modes only affect the volume of the amplifier output in iDSD, they have nothing to do with bypassing the battery. Turbo mode will deplete the internal battery faster than normal or eco modes. To power the iDSD from laptop/computer USB port (vs the internal battery) - simply turn on the iDSD then plug in the USB cable. This way the battery can be 'bypassed', however, it is still needed somehow for iDSD to work. Completely or almost completely discharged battery prevents iDSD from even powering on with the USB cable connected or not. Hope that helps.

Thanks, that makes sense.

I edited my previous post, the correct way to say should really be:
 
"To power the iDSD from the internal battery - simply turn on the iDSD then plug in the USB cable."

Looks legit to me. Just the website is half-cooked and made from a template, nothing on About Us page.
