Jan 25, 2010 Rating Laptop Power Supply by: Support Hello Mark, From your discription you are getting voltage from the laptop AC Adapter to the internal power supply of the laptop but the laptop will not power up, if this is correct and the testing of the battery only gives you 1 volt then I would say the internal power supply of both laptops have failed. If the AC adapter will supply the given voltage and amperage on the lable of the adapter then the power supply should power up the computer with out the battery installed, it should also charge the battery. Not doing either indicates the power supply has failed. Hope this helps...
