95W Power on M4400

Anyone seen this? Cooler Master SNA 95?

Can I use a 95W Power Supply for my M4400 along with the 130W Supply I would leave at home?

Its new and nice as #&$*#(### for guys like me who spend an hour to an hour and a half on the metro then a 2-6 block walk into the offfice?

This is small @
Dimension 75 x 17 x 145 mm ; 2.9 x 0.7 x 5.7 inches

If the PSU makes itself recognisable as a DELL PSU, then yes, you will be fine.

Dell PSUs transmit data over the powerline to the laptops - things like the power capacity etc.

My M6400 works just fine* with a Dell 90W adaptor.


*By just fine, I mean it runs slowly and charges slowly, but it does at least work.

 

Looks really interesting. If you buy it or find out that it works please let us know. Im interested in getting one for myself as well.

 

Reading the specs, I don't think that it will work with the M4400. It doesn't transmit the power ID etc. Your laptop will work, but it won't charge the battery and it will run slowly.

 

Anyone know of any other power adapter that would work? Small being the keyword!

 

So I can use a 95W Dell supply?

That stinks, I suppose I will end up getting another M4400 supply, leave one at work and one at home. I do have an extra 95W at home I could use, Dell branded.

I wonder how long before the technology is there to make these units no more than a wire, or even better over the air charging like this article @ http://searchmobilecomputing.techtarget.com/sDefinition/0,,sid40_gci1307218,00.html

 

Yes, you can use a Dell one no problems at all.

The reason behind this, I am guessing, wasn't primarily to prevent users from using other PSUs, it was so that a Dell laptop could identify the power capability of the PSU and not burn it out. Otherwise, if I plugged my M6400 into the 95W adaptor listed - if it (the M6400) didn't take any precautions then the PSU would melt pretty quickly. As it is, I can use any Dell branded PSU and the M6400 modifies its power requirements accordingly. If that makes sense...

 

The Dell 95W left over from some of my previous laptops works fine with my M4400...

 

i thought of this issue as well, because i travel with my laptop from home to office every day.

i asked my dell rep to throw in a spare power supply and he did so for no extra charge

but anyway, one good thing about dell adaptors is they're quite common and u can pick one up for cheap on ebay to leave at the office.
