Jabra supreme wont turn on

The headset light turns off when it is at full charge. If it is not charged yet it will be illuminated red.
Found this in the online manual:

I opened mine into the on position and the charge light went from blinking to solid red.

The headset has to be in learning mode first for any phone to find it, press and hold the power on button for 8 seconds until the power light comes on and stays on then search for it with your phone, pairing code can be 0000

seeing the red light tells you that the jabra isn't fried or shorted and that there is life but there is a problem, the red light isn't blue when it should be. so have you read the directions your ear piece came with when you first bought it?... hold the on button until you see the blue light stays on.(blue light will flash fast then slow then come to a complete stop and stay on) once blue light stays on that should mean you can now find the ear piece on your cell phone to link up. if problem still isn't fixed then you might as well buy a new one.

Try a tank of supreme gas, plus a can of SEAFOAM in the gas tank.After running about a half of this tank out. Pull positive post off the battery for about 1-minute. This will reset computer, and it might clean up the fuel problems that you are having. If it keeps on, change the O2-sensor out and do the above steps again.

its the starter

I had the same issue. So what I did was get a small screwdriver, opened the A210 case removed the battery. You will notice orange tape (remove it) then attached to the battery is a small board (the defective part) . Cut away the board, then you will need to solder the wires back to the thin metal film leads. And voila it will now charge, make sure to never let it charge for more than 2 hours. Do this at your own risk. Of course this will void the warranty.

I had not used my A210 in a couple years, and when I needed it again now, I TOO GOT THIS SAME EXACT SYMPTOM: where it would light red (charging) only for 2 or 3 seconds, and then be off. Hours on the charger and no charging or difference. I tried plugging it in a few hundred times to see if it would "jump start" for the 3 seconds to add up, no luck. I WAS VERY GLAD to read MightyFrosty could change something inside and get it working. I followed his advice up to "removing the tiny circuitboard on the tiny battery and resoldering". Instead (got the case open with a razor blade, gently) I removed the amber tape that wraps the battery/circuitboard assembly and tried first "jumping" the red to the "+", nothing~ but then jumping the black to the "-" the RED LIGHT came on and STAYED ON! (but only while "jumped". Better yet after some 20 minutes of "jumpered" charging, the RED LIGHT STAYED ON even when I removed the tiny jumper~! (a tiny wire is all, bent to touch the black wire solder spot and the "-" battery lead). so IT APPEARS it CAN CHARGE PROPERLY on its own once the battery has a little juice in it! It is charging completely normally now (red light solid, no jumpers, and with no cuts or circuit removals!). I believe I can reassemble it all tomorrow and have a non-modified operational bluetooth Jabra! Thank you MightyFrosty and good luck to all!

I contacted Jabra and they said this problem is due to a bad internal battery. There is nothing that can be done to fix it. So I returned it to the guy who sold it to me and got my money back. Purchased another from a different vendor, and this one works great. That's the only solution!
