Advanced port replicator power supply

Question

I have a inspiron 600m laptop that uses a pa12 power supply. When I hook up the power supply into the APR and plug in the laptop, I get a error that reads the power suppy is not supplying enough power to run the APR. I noticed that the APR states for use with pa10 power supply.  The pa10 has 18 v. and 3.5 a. The pa12 has 19.5 v and 3.34 a. Is this the cause for the error? Seems to me that I would be getting more power from my pa12 than my pa10.  I just want to know someones opinion before I go out and buy a pa10 power supply.   Tim

I'm not expert on electrical stuff here, but often notebooks and docking stations are powered by either 65w or 90w AC adapters. Sometiems 120w, but not often.

It's very possible that you may have gotten your ac adapters mixed up, so if they don't show the listed wattage on them, try swapping them around. If they don't work, i dunno if you can figure out the wattage from the ratings listed on the adapter (if it doesn't list wattage) i'm sure someone knows a forumla to do so.

Yes, the 600m uses a PA-12 and the APR requires a PA-10. The PA-12 puts out 65 watts. The PA-10 puts out 90 watts. That's the difference.

Thanks for the information. I didn't realize the wattage difference.

The PA-12 in fact has 19.5V and 3.34A, which makes 19.5x3.34 = 65 W The PA-10 has 19.5V and 4.62A, whoch makes 90W. The 600m works with PA-12 and PA-10, but when using the APR, it requires the PA-10.
