    Hai. I've Asus k55vd model, i3 processor, 4 gb ram, 500gb hard disk, 2 gb graphics card. I've certain doubts to clear.
    1) How to switch between battery and AC power? Is there any key combination ?
    2) Consider that the battery is fully charged(100 %). Still after that if i use the laptop while the AC power is still on, will the laptop use the AC power or battery power ? Is there any harm in using the laptop when the charger is on, after the battery has been fully charged ?

    Thank You

    1.)There is no physical switch to switch from battery and AC. You just unplug it.

    2.) Even if the battery is fully charged it will continue to use AC power so long as it's plugged in. Now days there is no harm to the battery while using and it's plugged in. The battery's (and all electronics) worst enemy is heat. Buy a cooling pad and your have no worries whatsoever.

    I own 2 laptops. (See signature.) And game a lot on both. I have never had an issue with my batteries before. (I did have a too hot room (ambient temperature should be taken in account while gaming.) and it caused some issues. I have always used a cooling pad though where ever room allowed it. Also my Asus laptop doesn't allow removal of the battery at all. At least not without taking it apart. Best thing to honestly do is to run the laptop battery down once a month until the laptop forces standby or forces shutdown. Then fully recharge it. This is to calibrate it and to condition it (You should actually do this to just about all electronics that have rechargeable batteries, cellphones, tablets, etc.) Unless you need to, don't continue running the battery down fully all the time, you will shorten it's life span, since the battery has a limited amount of recharges before it won't fully charge to 100%, not to mention most laptops will run in a lower power state, so for gaming laptops it won't play games as well.

    If your truly paranoid, charge the battery up (and if you can) remove it from the laptop. and only use it when you need to, but I have never done this as now days laptops have circuitry that prevents overcharging and such, and I have NEVER had an issue with my batteries, they have always had a proper charge and have been ready for the inevidential power outtage I have here. (Living in the country can be nice, but does suck sometimes. lol)

    Hope this helps out some! :)

    Mostly what he said.

    If the laptop and the battery get real hot at any point, try a cooling pad or even try to remove it for the time you use the system under full load. Using AC with the battery in the laptop is fine as long as there is no heat. System should tell you "plugged in, not charging", so it's not like the bat gets charged 24/7 like this.

    Do not let the battery "die" in the laptop, always charge it sooner.

    Do not perform full charging cycles unless you have to. Just use the battery only when you need to and you should be fine.

    Keep in mind that sooner or later all batteries will lose some capacity, it's normal.

    Hai. As you mentioned "plugged in, not charging", my laptop once displayed this message. But after that when the charge reaches 100%, it is not displaying that message. As i tried to switch off the charger, when the battery was 100% full, it displayed AC mode. Could you please tell me any way to display the message "plugged in, not charging", when the battery is 100% ? Thank You

    Yes, it should all be handled automatically by the EC.
