Tired of ur 130w cememt block power-brick? ALTERNATIVE! - Page 2

I've heard that dell's don't play nice with universal power supplies, because of different and/or wierd plugs they use.

It doesn't work that well with mine...

I have this Kensington 120w PS and the dell adapter for it. my e1705 bios reports it as 90watts only. It is putting out more than that however. I'm able to game on my e1705 with 7800GTX on it without cutting off (no battery installed either of course) BUT the lcd backlight will dim/flicker when I'm playing really intensive games like Oblivion. The stock 90 watt adapter will just cut off power so I know this aftermarket adapter is putting out more than 90 watts. BTW this screen dimming/flicker doesn't happen with the geniune 130watt adapter. Also Duracell makes a 130w adapter in the same form factor as the Kensington, but I've only been able to find it at Dell. I dunno if anyone's been able to test it on a graphically instensive game on the M1710/M170/Xps2.

130 watts is nothing. Scroll down to about 8 lines from the bottom of this page.

Taking this article from another thread, I think that the 120w adapter can be used with the XPS M1710 with the 7900 GTX.

Look at the 1st graph. The XPS M1710 draws out 107w at PEAK load........just something to think about.

With the Dell systems its more than just how much power is needed. The AC adaptor communicates with the BIOS via the center PIN in the connector on the AC plug that connects to the computer. This is how the system determines what AC adaptor is attached. If the BIOS does not recognize the proper 130watt (or larger) adaptor it will not run at full power.

Hmmm... I know that this isn't always the case but... Bigger = More power capacity. I'd be happier with the Dell brick. It's got warranty and product testing written all over it, why try to ruin it for 2.5lbs?

I can confirm that on AC power, it works fine with the M1710 ... the BIOS recognizes it as a 130W power supply. I haven't tested it with the auto or air adapter, but someone said it dropped down to 90W with the auto adapter ... but most cigarette lighter ports may actually be the limiting factor on that--most aren't spec'd to provide that much power. I believe that air power ports provide even less wattage--something like 70W

Edit: For anyone interested, I have attached a pic of the Duracell side-by-side with the Dell power adapter. The Duracell is slightly wider, but much shorter and much much thinner. Also, at 6 ounces, it weighs less than half as much as the Dell power adapter. That said, I'm not sure if it is really worth it since it is more expensive if the auto/air functions don't work properly.

That 130W Duracell looks like it fits the bill, but in the list of "designed for" notebooks, the 9300, E1705, and XPS Gen2/M170/M1710 aren't listed.

Yeah, that duracell one looks nice.

Also remember that dell prduces bricks that serve one purpose, to power the system. They do it cheaply and efficiently. That doesn't mean they are making it as small as possible.

Newer, more expensive technology can take the same dell brick and decrease it's size as you can clearly see, yet still maintain the same output and specs as OEM.

JMO though.

Perhaps the smaller units are switching power supplies, which are more efficient and cooler. The others may be large and hot because they are continuous?

I don't think that's true, I was able to run two inverters, one 150W and one 300W simultaneously and able to run a 130-watt XPS Gen2 and a 90-watt 9300 at the same time, using two different cigarette outlets. Both running at full speed. However I would highly advise against plugging two machines into one inverter, even though it may have two outlets on it. That blew one of the fuses in the car. That said, I'm really interested in one of these for travel, and keeping the original on my desk at home. $100 is a bit steep though so if anyone has a good Electronics and Accessories coupon I want it

I used to be RV Tech working on those inverters is one of my things that I loved to do when customer do Q's & A's. Anyhow your Cigarette lighers have of 15 amp fuse thats about 180 watts limit but I would not go higher than 150 watts due to limits and if you go to limit or higher your wire will get real hot. I seen people tried to do this on their own and not get right wires for it end up burning whole trailer or car down to ash. Even big 18 Wheelers gets burn too.

Now if your planning to go higher than 150 watts you MUST make Hardline that goes from batt stright to inverters, Also add Fuse to handle load and if shorts out it will blow than to burn.

you know what people would say when car on fire "Burn baby burn"

Sorry if I ran off topics but I use my Power brick to keep my hot Drink HOT!

Just to confirm, my M1710 does charge with the Kensington, but won't boot with it plugged in because it "sees" a 90W charger. When up and running, my M1710 is running at half speed because it's not detecting a 130W adapter.

Anyone know of a way around the 130W XPS BIOS lockout?

BTW, I only use this charger while traveling, not for day to day use. I have docking stations and the normal 130W brick supply. But for travel, I want to pack light!

Thanks.
