My T1000 has been claiming to be discharged by changing its light from green to red after about 2 hours instead of the 4 that is claimed. The manual says that there is only supposed to be 10 minutes left before disaster strikes, so I have only recently started experimenting. It appears that there is about an hour left after the color change, and I have now calibrated my copy of "Battery Watch, II" to give me useful warnings. Some curious things happenned during these experiments: Initially the light would turn green immediately on connecting the charger; but when the power was allowed to get low, the time to turn green lenghthened. With about 10 minutes power remaining, this time seemed close to a minute. In one test, the power got so low that the light remained red until I turned the machine off many minutes later. On repowering, I was told that my HARD-RAM had lost data and needed to be reformatted. By contrast, the "deep discharge" cycle of "Battery Watch" has never lost data. The relevance to the topic at hand is that the indicator light itself may be the weak link here. Some other way of testing the battery might be needed in order to discover the truth. -- --R. T.
