Is 130W power supply enough for Dell XPS 17 L701X?
My laptop (Del XPS 17 L701X) started to freeze randomly, so I was thinking that my power supply may be failing (sometimes my laptop also lost power if I the power supply a little bit while connected, sometimes the same supply made a buzzing noise). I have to say, unfortunately this supply was not genuine Dell part, but some "Delta Electronics" supply. Anyway, I googled for Dell genuine power supply and found this one: Dell 130-Watt 3-Prong AC Adapter with 6 ft Power Cord
So that is one that I ordered (bear in mind, I don't have the original one that I bought my laptop with), but when I plugged it in, my Dell issued a warning, that AC power supply with only 130W is connected, the system may operate slower and that I need 150W or more. Turns out my Laptop originally came with a 150W power supply, but even at the DELL official page it is said, that this 130W supply is the real deal. So I would like to know it this 130W supply will be enough or should I send this one back and exchange for 150W one. Do I have the risk to not to have enough power?
I have found on one page that this particular laptop consumes 123.2W on full throttle, if this helps (I have no means to test this myself, I believe).
