Hey Chris
No charge light despite being on charge for a fair amount of time. No visible damage to the charging port. No luck with the refresh attempt. May be that the psb is shorted, but before it died, it simply refused to charge until the battery was drained, hence me thinking it was that. It's only a cheaper model and I've jumbled it around a lot (carried it in a backpack) 18 months of life is understandable still I am curious to know how it could totally fail.
