I just ordered a R13 (R7-371T) computer and was looking for an external backup battery that had the correct size connector. I did a search for extra AC charger and they listed that the connector was 3.0x1.1mm. I have seen external battery chargers that provide the 19V and 2.37A but the best fit tip was 3.0x1.0mm. Are there any owners out there who have an external backup battery for the R 13 and if so could you tell which one your purchased? Is the tip specification correct (3.0x1.1mm)?
