Review title: Only worked 5 months on a 600m
Product review: I'm also joining the unhappy list of customers. My adapter worked fine with my laptop but one day it stopped charging the battery. The next time I rebooted I had the famed message error message that the "adapter could not be determined". Now my computer runs at 1/3 of its speed, has an annoying message on bootup, and won't charge the battery. The original adapter lasted 4 years under heavy use so I was hoping to get at least half of that out of this one under light use.I plugged in another adapter from a friends laptop and things work fine. No error message and the battery charges.
