Then I will try to connect the adapter power, actually can also be used. The But with 1 to 2 hours later, and smell the smell, I found the adapter quite hot, I quickly pulled. The The The Ask what is the matter ah? Now dare not use ...: Hello, your machine in the transformer burned, this time do not connect the adapter to the computer business. Because your adapter output has no 19V constant pressure, if the voltage below 19V better, if more than 19V, and higher than 25V, then your computer will be very dangerous, at any time may burn the machine. If your adapter is not outside the damage, then you can certainly get after-sale warranty, if there is external damage, after sale may be said to be man-made damage is not guaranteed, this time your attitude to be tough, You can seal the adapter intact, no damage, man-made can not be destroyed due to the request to replace (because the adapter is no screws, only violence to open). If the insurance, you can get outside to buy power, OEM 40 or so, but I suggest you buy the original, 2 hands are ok, 80 or so, because the OEM adapter is quite unstable, I was doing laptop repair, repair To a lot because the adapter burns the machine.

Alternative adapter is more, sometimes even if the parameters with your adapter, but do not plug the light, so buy the same model of your machine adapter, and then try on the spot card machine on the line, the original adapter do not know the price , Because what things stick on the brand and the original is very expensive, generally 200-600 or so, personal recommendations to buy a substitute can be, we have a lot to buy here on behalf of the adapter, basically not a few problems! In your side there are some physical store ah, repair shop ah, or the Internet to buy, but the Internet to buy this thing can not be tested in person, and perhaps some trouble, if you want the original adapter, then you some side of the entity The store can generally be set to, or to ASUS service station is also OK, but the price of the market to be a lot of expensive, you can first ask ASUS phone to ask. good luck!
