    Laptop suddenly turn off when main power turn off.


    Hi to all Eight forum.
    I m here with a strange problem, it happens from yesterday, the problem is when I playing games on my Dell inspiron N4050 and then the main power where the charger pluged in is turn off (it is the most problem in my country that there is heavy short fall of power), the laptop is remain ON just for 2 or 3 seconds and then its suddenly OFF. its not happening before, why is that,? why is the laptop didn't get power from the battery.?
    .
    when not playing games. and the main power (electricity) is gone, then this problem is not occurred.
    plz understand my problem and reply me.
    sorry for my bad English.

    Could it be overheating protection?

    Could be many things:
    I would check the power settings to see how your system behaves.
    Might just be that your battery doesnt have enough charge, capacity is under xx% and it goes off automatically because of that?
    Let me know !

    Many possibilities. Bad battery. Bad charging port. Bad connection between the port and the battery. Bad battery board. Bad motherboard. Bad bios. Heck, even bad user is a possibility.

    laptop, battery and user is all right, laptop almost new, I doubt in power converting system, which is tripping and didn't convert power from charger to battery, (in actual state, when pluged in charger, laptop didn't get the power from battery, it did get directly from charger, battery stay unused and just charging, when its full charged then it still stay unused, and when charger power goes off, then some kind of system immediately transfer power from battery to laptop and the laptop didn't feel the slightest disturbance of power loss)

    I checked it, its only happens when I play some heavy game. currently I playing 2 game, Resident Evil Revelation and International Snooker 2012,
    yesterday, I face the problem with both games. but now, a few minutes before writing this reply, the problem did not happen with Snooker game, it is really confusing.
    problem not occurred when laptop in normal state, browsing internet, watching movies. etc

    Your laptop comes in 3 flavors of processors, these are the heat limits of each..



    B950 85 c

    I3-2330M 85 c

    I5-2340M 100 c

    You can get in the high 70s c very easily, even just watching youtube HD full screen..

    Download and install CoreTemp, its free and will show you your core temps.. you can have it warn you about dangerous temps, or even put your laptop to sleep or shutdown when critical temperature is reached..

    You may need to sit your laptop on a cooler like I do.. Its not bad it keeps it balanced on my lap without plugging the bottom holes where it breathes from.. I dont even plug my cooler in, just the gap is sufficient..

    Check your temps, let us know..

    appreciate your reply. but you didn't get what I m trying to say or I did not able to tell you clearer.. let me try again,
    its only happens when I playing game and most important thing is when plugged in charger, and the laptop suddenly turn off exactly the moment when charger power goes off. so is it a heating problem or some sort of power problem.?
