Have you used it for more than an hour or so, and then given it a full 4 hours on the charger...and then did it still keep working for a long time after that? If yes, then a clue is that IT WORKS! It heats and vapes! Therefore, NOT THE BATTERY!so after writing to PV to ask about my solo and the warranty i had left, this is what i got back:
We have spoken with Arizer directly and here is what they told us. The battery in your Solo is only under warranty for one year, but the rest of the solo has a 2 year warranty with a lifetime warranty on the heater itself. In order for Arizer to determine the cause of the light issue you will need to send your Solo to Arizer directly for testing. If it turns out to be the battery pack, it is not covered under the warranty any longer and you will have to pay a fee for the repair, if it is not the battery pack causing the issues it will be repaired / replaced under warranty.
so now they leave it up to me to "gamble" here are my options for my still working but acting funny Solo
1) hold on to it and hope nothing is wrong and ignore the lights cost: nothing
2) send it in for warranty and find out its not the battery but something else cost: shipping charges
3) send it in for warranty and find out it is battery cost: shipping and repair
not too sure i like the options i am given. i may have to wait this one out
I'm speculating of course, having no knowledge of batteries or electronics...zilch! Circuit board problem, maybe...but that would be Good News, warranty-wise
