Removed battery and attempted to run computer on AC cord alone without success.When both batteries were completely dead the computed shut down. Does not operate on AC alone with or without battery installed and will not charge batteries. The light at the charging connection comes on but computer appears to not be receiving power for operation or charging.
I switched the chargers to another HP and they appear to be working properly so I'm guessing that the problem is within the computer not the charging units.
