Lenovo T580 - The connected AC adapter has a lower wattage than the recommended AC Adapter which was

2020-02-18, 16:14 PM

"The connected AC adapter has a lower wattage than the recommended AC Adapter which was shipped with the system.
To use AC power, please connect the AC adapter which was shipped with the system.
Press the ESC key to continue."

 

The adapter is the one that was shipped with the unit....Have tried 4 different adapters that are the same. 

 

Does not charge on the ThinkPad Ultra Docking Station / Type 40AJ    as well....Tried 4 different docks

 

Have pulled battery, pushed and held the power button for almost 1 minute and repalced battery. All firmware and updates are up to Date per Lenovo Vantage tool

 

Thought? Suggestions?

It sounds like the power circuitry on the motherboard has gotten messed up.  Are you still under warranty?

Does it work without the docking station?
Are you using a 135W adapter with the docking station? The latest 40AJ firmware updates have caused my docs to only work with 135W and greater adapters. I previously had used the 90W adapters that came with the docs.
