So my Asus UX31A I take with me to on site calls wont boot. I have tried every thing I can think of to get it to boot. I hit the power button and the hdd, caps lock, and power button lights come on for a second and they all go off. It does it when plugged in and just on the battery. I check all the connections inside all seem good. There is no visible damage inside. Its never been dropped or been wet. I treat this bad boy like a new born baby. Any ideas would be much appreciated Thanks.
 
Don't know if you thought of this but did you check the charger voltage. Battery could be dead and charger not putting out enough to power the machine. That's where I would start
Sorry forgot to mention that I was able to power it on once and drained the battery and then charged it fully. Then I closed the lid and when I opened up the pc later the power light flashed and it turned off.

So you only know its charged because the lights tell you it is? If I am understanding you correctly you have not been able to get turn on since draining the battery? I would try a different charger that is known good anyway just rule that out. You can also try removing the battery and charger plug and press and hold the power button for 10-20 seconds and see if that works before getting into pulling ram and checking for internal hardware problems.

Also make sure you have no usb devices plugged in or anything other than the power.

I it was charges fully and unplugged and used for about a half hour before wouldn't turn back on. No usb's plugged in and ram is on board. I tried removing the battery and charger. The power button is a keyboard key on this ultrabook and others online have said they had keyboard problems with this model. Would a faulty keyboard cause this? If I close the lid when it is on and open it back up it shuts it self off so I don't know how the keyboard would cause that.
 
You know I didn't realize it was an Ultra book I missed that completely.

Have you tried a different charger?

Whats the condition of DC jack?

A bad keyboard could be the problem ... but I don't think you would get any lights at all if was bad. I think it would non-responsive.

Pull the mother board maybe look it over good maybe some bad solder joints or circuitry issues.

I would lean more to bad motherboard at this point.

I don't actually get to work on the small xenbook/netbooks to much and when I do it's mostly software issues.

I tried a different charger a little bit ago and its the same issue. I will pull the board out here in a little bit and inspect it closer. When I had it open the side of the mobo I could see looks mint including the DC jack. Will remove it and double check every thing. I may order a new keyboard and try that if its the same status tonight. Id rather start with 30 dollar keyboard than a 300 dollar mobo lol. Thanks for your input Ray you reinforced what I was thinking.
 
This laptop is, by far, the worst most horrible POS I've ever seen. Worse than the HP DV6000 series laptops. I had the same problems you had and this is what I found out.

The research I did was extensive. Unfortunately it was a long time ago and I forget some of the details, but I'll give you as much information as I have. Apparently this happens when you allow the Lithium Polymer battery to drain too low. There's something on the battery that is linked to the motherboard. If you replace the motherboard, it will do the same thing and you'll damage the new motherboard just by plugging it into the old battery. You need to make sure and replace BOTH the battery AND the motherboard at the same time and don't mix and match them. I don't remember why, but you need to trust me on this.

For me, it didn't seem worth it but my client insisted that she wanted it fixed. I replaced both the battery and the motherboard and it fired right up.

I also heard that the keyboard might be the problem, but I find that hard to believe (though it's not unheard of). In my case, I replaced both the battery and the motherboard and everything went smoothly. But if you want to gamble on the off chance that it's the keyboard, it would certainly be cheaper than replacing both the battery and the motherboard.
