Hello, everyone! 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 and I do not have the original any more. Anyway, I googled for Dell genuine power supply and found this one: Dell 130-Watt 3-Prong AC Adapter with 6 ft Power Cord
That is the one I ordered, but when I connect it, my laptop issues a warning, saying that AC adapter of only 130W is detected ant the system will work slower. I need to connect 150W or more (!) for the computer to operate at full speed. Which is strange, because this exact power supply is listed on Dell's official page. But it turns out that my laptop came with a 150W power supply originally (which I do not have anymore, so I cannot test it or compare it with the new one).
So, I would like to know if this 130W power supply is powerful enough for my computer or I should ship it back and search for a 150W one? I have no means to make a test, but I found on this page, that at full power l701x consumes about 123W.
What do you guys think and what are your thoughts about this situation? Thank you in advance!
If I understand correctly it has a discrete motherboard, because it's got nVidia GPU and no integrated graphics. If I have to have a 150W power supply, it is indeed very strange that Dell is stating on their homepage that this 130W supply is the one to go for, because I believe there is no l701x with only integrated graphic.
