Asus g50v laptop boot failure

Hey guys, my g50v is on vista, and I was getting constant blue-screens suddenly after 3 years of no problems, so I went into bios and touched something called Intel TXT, and enabled it.

So then, my laptop will not POST. I hit the power button, and oddly roughly 5 seconds later it turns on, then 2 seconds later turns off. If I have it plugged in, it will keep repeating this.

I cannot enter bios, or boot from a CD, because it turns off far too quickly.

I tried disconnecting the cmos cable following a disassembly guide, as well as hitting the pin hole reset button, but I still cannot boot!

I've also tried taking out the battery, unplugging it, and holding the power button down and trying to drain it, then hitting reset and resetting the cmos cable.

I have no idea of what else I can try I'm almost 100% positive this is not hardware failure.

 

Hi,

It sounds like you have done the process correctly. I don't see any threads where people say that particular notebook cannot reset CMOS so I am wondering if you should double check your procedure.

Which disassembly guide did you use? The reason I ask is that this guide (look at the CMOS cable they show in step 4) seems to show a CMOS cable that does not look like the battery power cable where people had success. If you disconnected this cable for a few minutes it would likely not have removed power from the CMOS battery.

In these two pics they are showing a square power connector with a black and red wires being disconnected for a few minutes.

This is a thread with your exact problem

Here is one that sounds easy if your Notebook looks the same with the connector near the wireless card.

 

Just to double check you've taken out the laptop battery not the cmos battery?To make doubly sure of a cmos reset you need to remove the power cable,laptop battery and then the cmos battery which is shaped like a small coin.

This is of course if you have no success with sach's method and if this method isn't already detailed in one of the links.

 

Appreciate the replies guys.

I have taken this girl apart, and doing so I damage the keyboard connector :cry. The little cable has a white lock on the end and it's just cheap plastic that broke too easily.

I cannot seem to find the cable shown in the picture. I'm just not sure where to look, because below the keyboard it's not there, and on the motherboard front side I don't see it : /

What is that little pinhole reset actually reset? I figured it had to be cmos, otherwise everybody has to take their laptop apart to reset it lol?

Any hints on where to look appreciated

 

Working with laptops especially the keyboard cable is always delicate work. Sorry about your connector.

I'm not sure exactly where the connector is from the pictures. No one has a clear shot of the whole top or bottom of the laptop.

These are from a different model but hey are clearly going from the bottom. http://picasaweb.google.com/ndmihai/ASUSM70VmCLEARCMOS#

This is from the disassembly guide for your model where the blue thing on the left, in the top picture, with the piece of tape over it is the battery. It should have the black and red wire coming off it and you want to find where those wires connect to the motherboard and disconnect it for a few minutes.

Just curious if youcan make sense of these three pictures. Does it sound like under the silver plate below the keyboard you would find the black and red wired connector?

I found it... It took over 50 screws to get to it.

Just unreal, it was on the back plating of the motherboard, and I had to take apart absolutely everything to get to it.

Even if you're not a religious person, please say a prayer for me. Even after I get this pieced together again it may not boot.

positive tihnking!

 

Good work!

Go slow! Even then I find laptops take at least two tries putting it all back to get things right. Tiny pieces with not much room for error.

The keyboard cable may work without the actual locking mechanism. http://i275.photobucket.com/albums/jj284/davidli919/G50V_Page_10.jpg It doesn't take much contact to enable the keyboard. If you can just get the cable to stay in place without the locking mechanism.
