> AC adapter doesn't give an SL-C760 a full charge in the USA

I purchased my SL-C760 on eBay. I noticed that the battery was not getting a full charge. I thought that perhaps the battery was dying, since the computer was already used by someone else. I then read elsewhere on the web that the AC power adapter is meant for use in Japan, so I tried using the Zaurus SL-5500 power adapter. The model number of the SL-5500 adapter is EA-70. The SL-5500's power adapter was able to give the battery in my SL-C760 a full charge. The power adapter that came with the SL-C760 is for 100 volts.

Ditto on both my C860s. Amber while charging, off when complete, blinking if no battery (bad battery??).

One other thing to consider. The power input to ALL the Zaurus's is finicky, both low voltage AND HIGH Voltage. I tried a few other regulated power supplies that I had, around 4 to 6 volts.

The 5 volts works best. the "4.5 volt" high output (2 amps) supply worked well. The nominal 6volt supply I had wouldn't work. A charger output of greater-than 5.5 volts will prevent charging just like less than 4.5 volts.

The zaurus, especially the SL-CXXX versions take a lot of power to run, and to charge a near dead battery. A simple Walmart 500 millamp charger won't cut it. It may charge the battery only (with unit off), but probably won't allow the zaurus to run and charge the battery.

I noticed that the charger that came with my SL-C700 (tiny) will run and apparently charge my older smaller battery, but the charge light never goes out (indicating the charge completion) unless I turn the unit off for awhile. My old Casio Cassiopiea charger (also 4.5 to 5 volts) but 2.0 amps (2000milliamps). Runs and charges my battery, but the charge eventually finishes (light goes out), even while running. These newer little tiny chargers aren't the el-cheapo transformer / regulator type supplies, they are what is know as a "switching" supply. The end result is the physical size is much smaller than the older type of the same power rating.

Be careful. I have heard horror stories of ruining Zauruses with sub-standard generic chargers and/or using the universal types and getting the polarity wrong. Also, don't use the cheaper "unregulated" 12v car adapters to charge in your car, especially while starting the car.
