Asus Laptop Keyboard Shorting? Will a replacement fix the issue?

Hey guys, i have recently acquired a fix-me-up Asus G73. The laptop is near perfect aside from the keyboard.

When i first booted it up to the desktop, i tried to click on the desktop shortcuts, this is when i noticed that it was acting like someone was holding down the delete key. 10 or so "would you like to delete this?" pop ups would show up.

I fought my way to notepad and i found that it was typing just constantly. there would be a endless stream of numpad numbers, decimals, random enters, and backspaces. when attempting to use the numlock to shut it off, it would simply just press the "." button. Caps lock would get stuck off, and unable to be turned back on.

I first tried to update and re install all of the BIOS and all relating drivers. this did nothing to help the situation. I then tried to plug in a usb keyboard, but the computer wouldn't register any additional keystrokes from it.

Downloaded a keystroke recorder, and it showed that a fistfull of keys were "held down". I then removed the keyboard from the faceplate and the problem immediately stopped. I could then type using the usb keyboard, and the keystroke program showed there wasnt anything pressed. However when testing each key, i found that the backspace would also trigger "p". I then placed it back into place (without clipping it in) and the board started writing random numbers again. The seller has told me that laptop was sent to Asus for a RMA on it's keyboard in the past.

I am assuming that some of the leads in the Keyboard have somehow crossed or are broken. There appears to be some light brown "scorching" on the backside of the keyboards as well as the metal plate it sits on. I put a full layer of tissue paper between the keyboard and the base and then snapped the keyboard back into place. This solved the random number typing problems however the backspace key (and some others) will still hit multiple keys on a keystroke. I haven't bothered to unscrew the keyboard to look at the back side yet, i am waiting on my replacement to arrive first.

The back light does turn on when the computer boots up, however it doesn't come back on afterwards.

Aside from the keyboard, and a loose power jack (also replacing) the laptop is in perfect condition and operates correctly.

Am i correct to assume that replacing the keyboard will fix the problem? Is there something that may cause the new keyboard to start glitching out?

Is there anything that i'm overlooking?
 
Solution
It looks like the previous owner has spilled coke over the keyboard. So, once you have the keyboard out, check to see whether there are any traces of residue there. I don;t think your laptop' motherboard needs replacement.

Thanks for the reply, by "board" i meant the keyboard. The keyboard itself is clean and there are no sticky keys or signs of residue.

I am having the same problem. But in my case - the backspace button is being shorted. Randomly.
I replaced the keyboard, but the problem doesn't go away.

Stay away from ASUS.

While i never have figured out exactly what was wrong, i did end up getting a replacement keyboard (non-backlit) from amazon. They keyboard is working fine now and there are no issues.

I do remember that when I was fooling around with the old keyboard I remember flexing it slightly and it started to write different keys. Anyhow, the only issue I have with it is that the touch pad is a bit picky. at random it will not seem to register your touch, most notibly when you are putting pressure on the palm rest. So i still think there may be a issue. But who cares, we use mice.

I own three g-series laptops (two g73's and one g74) This is the only computer I have a issue with. Like I said originally, It was a used laptop that was known to have a couple issues. Including the power jack being loose. So Im really going to place the blame on the previous owner.

I have no issues with Asus, and I reccomend their products to anyone. They have been much more reliable than the pile of lousy dell's my family has acquired over the years. Heck, at four years old, the most I've done to my other g73 is replace its hard drive to speed it up. My g74 only has a issue with a loose power jack due to fault of my own. And I was even looking for yet another Asus g series to give to my girlfriend.


Though as a note, i will be getting the faulty G73 back from my friend to give to my girlfriend and at that time I will probably take some time and look back into this issue. If I end up finding the cause, Ill try to remember to message back.
