Lenovo T480 doesn't charge on inverter power

2020-03-15, 12:19 PM

My Lenovo T480 doesn't charge on inverter power (800 VA inverter with 150 ah battery). Does anyone know how to fix this? This is not due to a faulty charger I tried with different chargers and none of them charge the laptop on inverter power

 

 

Regards,

Karthik Pavanje

This might be an incompatibility between the charger and the inverter.

 

As I understand it, some types of inverters produce a 'sine wave' AC that should be compatible.

 

But some types of inverters produce an imperfect 'square-wave' or 'stepped square-wave' AC that may not be compatible. (This is only an approximation of the normal sine-wave AC you get from the normal wall outlet).

 

It's also possible that the peak current required by the charger exceeds the peak current capability of the inverter (even if the average power rating fits).

Hi,

    This exact problem is with me, any solution...

 

While everything in house including other laptop etc works but my office laptop T480, doesn't work as adapter seems to be supplying in consistent supply while on inverter.

 

Adapter model is ADLX65YCC3A

I recommend the Lenovo 65W DC adapter.

I don't work for Lenovo. I'm a crazy volunteer!
