Hi,

 I am getting this message on my Precision Workstation M50 notebook, when I boot System.

“Warning: 70watt (20v, 3.5a) AC adapter detected. System will not be capable of running in full performance mode a 90 watt (20v, 4.5A) AC adapter.”

I have tried switching batteries and power adapters but no use.

Can some one help me?

Thanks..
