thanks for the reply and the advice
the laptop is new, i have left the adaptor at home, and at my friends place for a couple of days, soon as i get home, i will check out if it still works on its own adaptor.
if the power unit has gone does that mean the whole laptop has gone, is there any way to charge the laptop battery in the meantime. what do you think are the chances that the laptop psu has gone?
i guess if i that is the case then i need to send the laptop without any "software" i have installed, correct?
