No response from my ipod shuffle 4th Gen, no power, no computer recognition

Dear all

I've seen several similar posts on the communities but I've tried everything I could see but couldn't fix my problem.

My shuffle won't turn on, it can't be recognised by my iMac when connected and it doesn't show any light.

I've tried several things:

1. resetting (several times) by turning off for 10sec and then on again.

2. charge via the wall charger for an hour...still nothing

3. apparently someone said we could plug it in and out of the charger until there is enough power to kick start something in case my battery is completely drained. I've tried that too for about 5 mins, still see no signs of any lights.

4. I have tried 2 original ipod shuffle cords and also 2 bought from internet, no difference. And yes, they are pushed all the way in.

Is there anything else I can try before giving up? Mine is just over one year old so it's no longer under warranty.

Thank you all very much

Regards,

Simon
