And to GreyFox7 who sent me a note about his 7 year old charger still woring: this is the porblme, most appear to work, but some of us have repreated issues whihc suggests it is the SP3 and not the charger. For the record, I have three chargers, and none work except that one manages a flickering light, occasionally.I bought my Surface Pro one week ago. Charged it immediately - no problem. Haven't had a lot of time to use it, so the battery only ran low today. Plugged in the charger, turned on power and - nada. No little blue light, no power to the Pro, no action.
I've checked with a multimeter and power is getting from the outlet to the transformer. It's coming in at 248V (I'm in Oz) which is a bit high since the charger range is 100-240V, but our standard supply tolerance is +/- 5%, and it wasn't a problem last week. Anyway, power is getting from the transformer to the connector at 12V, which is right according to the small print on the transformer. For some reason, power is not getting from there to the battery. The connector seems to click into place OK and nothing is obviously loose, missing or dirty.
Has anyone else had this problem and does anyone have any suggestions, or is it back to the store with warranty in hand?
