This weekend I went from home in Georgia to a weekend of work in Philadelphia, leaving my AC Adapter for my Inspiron 600m at home. So I checked to see if there was any third party adapter I could purchase locally. MicroCenter had a Targus universal adapter that listed the 600m on its package. It's a multi-source adapter (car, plane, wall) for $80. But when I checked the website I discovered the unit would power my 600m but not charge the battery. Apparently the IGO will not charge the battery either.
I chatted with tech support and all they could say is that adapters are available from Dell (shipping in 24 hours, not the one to two weeks claimed on the website), but I needed something that night.
Anyway I decided to make do with web access to email and using my wife's notebook computer.
So is there no third-party power supply that will work? And is there some proprietary circuitry needed for charging the battery?
I had the same problem with a Targus APA10US -It runs my laptop, but won't charge the battery. Too bad because it is 1/2 the size of the 1lb 'brick' supplied by Dell and would be great for on the road. Dell even advertises the APA10US on its website!
