    Why is the included AC Adapter unit on NP130 only 120 watts? Isn't that a bit short when the stock GTX 670m is 75w TDP and i7-3610qm is 45W equalling to 120 watts to be exact.

    Is everyone's AC Adapter only 120watts? I mean i can understand the 180watts on the Np9150 since the gpu upgrade like 675m/680m or 7970m have 100w TDP.

    Can anyone tell me how is 120w ac adapter enough when the total watts of the gpu and a quadcore cpu alone is 120w, then you still have the monitor, the hd and how is everything working on a 120w?

    Because not everything is 100% loaded all of the time.

    Also TDP is not always the actual power consumption.....

    The 3610QM is 45W including the IGP, but why would your IGP going full pelt at the same time as your graphics card?

    You can use a 120 or 150 w adaptor on the np9150. Unless you are blasting on graphics my np9150 with 670m never goes over 130w

    Actually when I googled the P151EM adapter's part number, it showed as a 135W one.

    Multiply voltage by ampage to get the power. Mine is 19.5 x 11.8 = 230w.
