ASUS G73SW - Fried Motherboard?

Hi, I think your adapter is defective, the reason you have no light on the laptop is you were using the battery instead of the adapter. Maybe a component is burn on the motherboard, but if you can try the adapter on another laptop, that way you will eliminate the adapter for the cause of the problem.

The problem may be only two things, the adapter or a short component on the motherboard, because when you connect the adapter, the light on it goes off.

To verify a short on the motherboard, you need a multimeter.

That's what I was afraid you respond, meaning, I don't have the schematics for your laptop, so I'm blind for referring you what to look for. But, if you can take a good picture of the motherboard around the dc jack, maybe I could tell you what to check. Also if we find the defective component, you will need to replace it, desolder the defective component and solder the new.

This is not an answer Supatony... I have the same problem with my Asus G73s but here is my story.

This laptop used to work until two years ago but thr reason was my mom lost the charger and we couldn't find a new one. So it was put away until a few weeks ago 2017, 2 years later when i was going to my second year in varsity and i needed a laptop. So we found this one deepbin the closet. When i found a charger with 19V 3.14A it didn't work so i thought the problem was with the charging cord.

Not excluding thr fact that its been off for 2 years, i took it to someone to look at and they told me they don't know.. Then they refered me to a place called the nerd herd, left it there for 4 days today thry called me in and told me that..

They fixed the charging cord but the laptop is stull not charging so they think that the problem might me the graphics cord or something like that and that will cost me R7000 more or less.

But they also said that, it might need a big ass charger with 150watts for the boost to be able to reboot. Now im searching for that and i need your help Supatony and Toms people. I don't know what else to do right now. I am only 19.

If the laptop is not powering up, at all, then it is DEFINITELY not the video card. When a laptop/computer boots up, it goes through a device check (known as Post). The post process happens when the laptop turns on, starts running, and checks all of the components before starting the operating system. It will "beep" several times, in the process, and those beeps will tell you whether there is a component that fails, or tells you that all of your component passes post. A video card is an output device. So, if it were the video card, you would get zero video and you would most likely hear a double beep, or a long beep, during post. There are really only 3 things that will "brick" your laptop; bad motherboard, no power (i.e. bad AC Adapter), or bad processor/chipset. It could be a combination, or all three, but those three things are the only things that would cause it to miss post. No activity, at all, will point to either the Motherboard or the AC Adapter. I would start with replacing both. AC Adapter first, since it is the least expensive and it never hurts to have a spare. If there is still no power, you will need to replace the motherboard, which you can get online for 100-200 bucks. Keep in mind, if the motherboard was fried from a surge, it is highly likely that you will have issues with other components, once you get the machine to where it function to post. Processors, Hard Drives, RAM, Chipsets, and Video Cards all draw their power from the motherboard. So, depending on where the surge happened, it could have "zapped" your other components, as well. So, your cost to find out whether its worth fixing will be the cost of the motherboard, plus labor.

Hope this helps. The good thing to come out of this is that, if the "Nerd Herd" told you that your bricked laptop was a video card issue, you KNOW that you need to find a new shop. DO NOT bring it back to them. Order the board online and take it to a reputable shop. The above information is A+ certification 101 and is the easiest IT certification to get. If the Nerd Herd can't even pass the A+, then you don't even want them touching your old iPod.
