E6400: is there any 2-prong AC adapter?

Love the NB, but hate the AC. Why it came with 3-prong AC while most NB comes with 2-prong AC? Is there anyway to convert?

 

Get a 90 watt dell "standard" adapter, those are 2 prong now.

 

huh.... almost all notebook adapters are 3 prongs

maybe, what you're implying is the power cord from the outlet to the adapter itself.... that would depend on your country

 

3rd prong is the ground line, its there for safety.

 

I think they may have gone back to three-prong standard adapters after the whole M1330/M1530 mess... but you can definitely still find two-prong standard adapters even if they are or aren't' making 'em.

 

I share your dislike for the 3 pin connectors and the heavier, thicker mains calbes that come with them.

The Dell 65W AC/auto/air adapter is two pin. It works fine if you have the Intel GPU but if you have the nVidia GPU then the BIOS (a) throttles CPU performance (can be over-ruled by using RMClock and settling throttling to 100%) and (b) only does a trickle charge on the battery when the computer is running (but is OK when it is off).

Alternatively, look at third party universal PSUs such as Belkin and Kensington.

I hardly think a bit of a thicker cable is a good reason to get a 2-prong AC adapter over a 3-prong...as Commander Wolf mentioned, it's already caused quite a fiasco with the brushed metal-body XPS notebooks that shipped with a 2-prong adapter. Since they didn't have a grounding prong, the notebook and its metal palmrest grounded their current via the next best thing: the user!

Shocks and tingling from the current were pretty common complaints. Using a grounded 3-prong adapter fixed the issue.

I'm not sure what the E6400 is made of; I've never used one, but if there's any metal parts on the exterior that you come into direct contact with, like the palmrest, chassis, screws underneath when it's on your lap, then I highly recommend sticking with the 3-prong.

Now that I think about it, it almost makes me glad my entire Studio 15 body is made of plastic.

 

The E6400 includes a lot of metal and I have had the occasional tingle from the front corners where the paint is wearing off but this gets fixed if I put some slippers on my feet.

I do a lot of travelling and have been in places where the ground is not grounded as well as many places where the mains sockets only have two pins.

Grounded power supplies can also cause unwanted side effects such as stray current loops.

Anyway, each to his own.
