I got the powertip for my notebook (which is listed as "power only - no charge"). I expected that this was just a CYA disclaimer because that tip also works with other lower-powered universal adapters which wouldn't be able to provide full power but it does in fact force the notebook into low-power mode (600 MHz, no charging). The BIOS says the power adapter type is "not recognized" on boot. Sounds like it's using something other than the power delivery ability of the supply to detect it. I'd like to be able to fool it into working at full power. Jim __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
