Bad AC Adapter?

[invictus]

I've got a remote user at work that supposedly has a bad AC adapter (it's the 72 Watt type for T2x, T3x, and T4x series). This is the first I've heard of one going bad. I was told by a third party that it's not charging up the laptop's battery. I just went and sent her a different adapter, and now that I've got the 'bad' one, I dont' know if I should try it out on a laptop or not. I don't have access to a multimeter/voltmeter to check the voltage that it's outputing, if anything.

Any suggestions?

This is the first I've heard of one going bad.

Second one today for me . It's possible that something in the power supply gave up. If you don't have a voltmeter and the replacement power supply charges the battery then simply toss it. IF the replacement adapter also does not charge the battery, then you have the same issue that the other poster here had today, which I attribute to a motherboard issue.

Not a bad supply, but the same non-charging issue.

This was the one I was thinking about:
