My t.sonic 850 mp showing "insufficient power"

This is a common problem with these players (first link). My MP860 failed in this way (insufficient voltage etc message)
I made a rig with laboratory PSU (several amp output) connected to USB socket and I know that that the problem has nothing to do with voltage (voltage was stable 5V - tested also higher up to 5.5V)
For a while a trick with holding the volume up button worked for me. (see second link) But once I discharged the battery to a too low level and the trick did not work anymore.
My conclusion is that that message indicates Li-ion battery degradation and charger circuit/FW declines to charge it showing misleading message. (battery made by Foxlink)
I tore my the player open and rigged charge circuit and get it working again. Photo: http://farm6.static.flickr.com/5063/5683361395_d59bef8142_b.jpg
Few suggestions: 1. Never allow the battery to be fully discharged. Charge at any opportunity you have. 2. Once you get the Insufficient input voltage message try trick with holding volume adjustment. 3. If 1., 2. failed rip it open and make charging circuit or replace battery. 4. Do not buy Transcend MP3 players. (?)

Your question appeared two times, I send my answer here also:

Try Powering it ON and OFF a few times, if this does
not correct the problem you can Reset the unit by pressing the "Reset" button for 3 to 5 seconds.
Is your T.sonic 850 properly connected to the USB port? If not, unplug it and plug it in again.
The MTP mode in the Settings menu should be set to "USB." In this mode, files
can be transferred by simply dragging them onto the T.sonic 850's Removable Disk drive letter.
You don't need any driver on PC in case of windows op.system.
If these don't help try study the user manual to find additional possibilities:

Good luck!

maybe you need some kind of driver. go to the website and check it out.

Do a full restore on the iPod because the files may have been corrupted.

press reset button & connect to the pc

Hi,

You can install 'Ubuntu' OS as an application inside windows. And login to Ubuntu OS, now connect your player, it will show all the songs, photos everything.

Hi,

When you switch on the Music Player(MP), go to settings->MTP
Under MTP, you can able to find two options, USB and MTP. It will be in MTP, select USB. Now you can able to play with the Player.

If this message persists no matter how long you charge the device then it is an indication that the battery has failed. Your best bet would be to contact Transcend for repairs.
