I've had several Sola lights, and have had similar, although not the same problem(s). During several fairly lengthy calls to L&M last year, they suggested resolving these types of problems in 2 ways: 1) return the light to L&M or the retailer for a replacement, and 2)try repeatedly plugging and unplugging the charger into the wall outlet. I've done both,and the latter seems
to resolve charging problems. Even still, it's obviously a great light, and so I never travel without a spare charger.
