I have an iBook that I tried to use on an inverter. Don't know where it(inverter) is right now, but according to specifications it should have worked. Looking at the adapter, it is one of the auto-sensing ones that detects 110 or 220 VAC, 50 or 60 Hz (like almost every laptop ever made by anyone) so they can sell the same brick in Europe and U.S.A. just with different wall plugs. Disclaimer: What follows is just a hypothesis! I think some (or all) kinds of autosensing power supply stays in 220V mode until detecting a 110V source because putting 220 into 110 circuitry is BAD and putting 110 into 220 circuitry isn't good but doesn't hurt. In this scenario, the inverter might detect the 220V as an overvoltage and shut down... OR the inverter is built with a delay to allow short term draws beyond capacity. The modified sine wave doesn't flip the PS into 110 mode, so its drawing 220. After the delay, the inverter shuts down b/c of overvoltage detection. Just a thought. -Eric J ===== PB145, iceBook Classic II(x2), Performa 405,IIci 6100/66 DOS Compatible, Blue and White G3 and random bits and pieces You are not drowning in old computer parts until you start charting tides... __________________________________ Do you Yahoo!?
