    I hate making similar threads, but this one is specific. I will be on a 12 hour international flight and I want to be able to charge my NP9377 during the flight. I am mostly concerned about the adapter I will need, a universal adapter for whichever power they use on planes (90W) that would work on Sager NP9377, which uses a huge power block. Could someone please recommend me one?

    Also, the first desktop PC I received in Europe, which was also the very first desktop EVER for me, I killed because it wouldn't come on, so I switched the PSU thingy to 120W and then there was some smoky smell... Obviously because Europe outlets use 240W and US ones use 120W. Do laptops have protections against that? I will be buying NP9377 in USA, so it will come with 120W thingy. I also have a 120W to 240W converter. What if, by chance, I end up flipping the switch the wrong way and use 120W setting for 240W outlet? Laptop kaputt? Being taking to hospital due to raging, pacing non-stop, hitting my head against the wall and screaming "Jahamalala! Jahamalala-LLAA! Diggy-Diggy Yo - Sasquatch is a whore!" and violent behavior AGAIN? That cannot happen. I hope they have anti-death for the whole 120W/240W problem. Its so easy to forget and just SHIZAM!

    http://www.amazon.com/Rosewill-Univ..._sim_pc_5?ie=UTF8&refRID=0BJTCK1VD7XT8VCSW6GW should this do the trick??? Are there better ones? Would I just ignore the power block that comes with NP9377 and hook NP9377 into the Universal Automatic Notebook adapter and then hook adapter to plane outlet? I am confused about all these things, wattages, etc.

    It would be helpful if someone told me a trick on how to get the isle lady to divert plane's power to my laptop instead of wasting it on some safety thingies, lights, steering, and whatever else, like UFO-dars.

    You are mixing a bit things up !
    The inlet voltage ( V , not W) is different among countries, most used are 110 volts and 240 Volts, as you said, european countries are in 240V,
    BUT , most of the PC adaptators are designed to operate at both voltages (on the specs : AC input), on notebook, the power adaptater adapt itself automatically !:), but on desktop PC you have to switch manually indeed :(
    so, the laptop you will receive will be ok automatically for all countries :) ( and yes, most of adapters have anti overvoltage protection !=))
    BUT, you have to choose carefully if you buy an after market AC adaptor, meanwhile the AC input is not a problem, DC output is !
    Your laptop is designed to operate at very precise voltage, is written under, and if you choose a aftermarket, it have to be the same voltage (like 19v), or be voltage adjustable ;) ), you have to pay attention to output power too ! the output current ( Amp) tell how much power ( Watts), you can draw : Power (W)= Tension (V) * Current (A).
    your NP9377 can draw more than 280 W while on heavy loads ( like gaming or video editing), that's why the power adapter is so big, (330 Watts) so the one you linked, will burn for sure ! as it can only deliver 90W at most ! ( DO NOT USE IT !)
    If you are just planning to just watch movies on plane ( or other very light loads), you can probably go to a 180w adapter, BUT DO NOT USE IT FOR GAMING or heavy loads !)

    So, to make simple :
    to choose an ac adaptor :
    Output voltage ( V ) have to be the same that the one they bundled you with your laptop, absolutly !
    Output current (A): ok if it's the same ( 16.9 Amp), better if it's capable of more ( but i don't think it even exist ^^) , very risky if you choose less, for your laptop , 180W ( 8.5 Amp) represent the bare minimum ( and i repeat : NO HEAVY LOAD !)
    Also, your power jack will not be anything near standard, so you will probably don't see aftermarket power adapter sold with this !

    about power on plane, i hope you have a wonderfull smile ! :D

    OK, so assume the plane can deliver only 90W, what would happen if I were to hook up the power brick that comes with NP9377 into that 90W outlet? Would I get SOME juice out of it??? I could wait an hour, play a game for an hour. Would that work, no?

    You could turn off sli and clamp the p state of the primary card to a lower clock with your standard brick and it would be ok.

    Will you have space for the machine however in your seat?

    I have drugs that are tasteless and work fast. I'll MAKE space. Nobody gets in the way of me and my PC, especially my baby G (Baby G because its SaGer, lol, get it? I don't... it makes no sense :confused:, but "G" rhymes with "PC" o_O and I am saying all that because I like emoticons on these forums - they are cute :rolleyes: LOL!) --->:oops:<----- LOL!


    Wait though, how would I lower clocks with a brick? Power bricks don't lower clocks AFAIK. Are you saying I should just reduce workload to a minimum and use the brick that comes with the laptop? I can disable both cards, use only Intel HD4600 graphics, minimum brightness, etc., use some battery-saving software that I hope comes with the laptop, and play only 2D games like Fallout 2, Baldur's Gate 2 Enhanced Edition, Grim Fandango Remastered (its 3D though), or watch movies, hardcore porno's, etc.

    You can use nvidia inspector to limit we the maximum p state.

    You need how many threads? You couldn't ask this in a np9377 thread or shockingly, ask a reseller?

    thank you Zymphad, great message , very useful, as the thread are talking about very differents problems, and can lead to big disscussion, and also can be found more easily than on a 200 + pages thread, i think multiple threads is ok.
    About reducing energy consumption, you can limit p state of GPUs ( or just lower frequency to 150 mhz ^^), you can also limit CPU power with windows, by making a personalised power plan, and reducing CPU max %, you can also select " passive cooling".
    I don't think you will be able to disable both GPU as you don't have optimus, the HD graphics is most likely not plugged ^^
    And basic stuffs : minimum brightness, no wifi, no bluetooth. If you do so , you will be able to use your computer with a smaller power brick !:)
    Anyway, for plane, i would recommand a tablett or a small notebook, not a monster :D
    About power output, if it's 90W, i think you can ONLY charge your laptop ( while offf), and make the 1hour charging, 1 hour gaming scenario :)

    So is it best to get a different brick for plane's 90W or use the stock/default brick, assuming use of passive cooling, P state, low brightness, lowest clocks, and very strong energy-saving profile???

    No need for a different brick, only the weight and size can make aftermarket useful.
    but i repeat, finding an aftermarket adapter with the kind of plug you are using on your sager is going to be very difficult !
