Hi, I have a spare AC Adapter, details on it are:-
Input 100-240V~1.5A 50-60Hz 120-160VA
Output 19V --- 3.16A
I am not 100% sure if it works ok, but can easily check this at my local pc shop (just opposite my home).
If it checks out ok, you are welcome to have it at no cost. It is only sitting in a drawer at the moment, not doing anything!
Let me know here if you are interested, I will get it tested and if ok I will then ask you here, to contact me via yellow envelope.
