No power after overclocking. HELP!!

Hey guys, well I've had my laptop for almost 2 years now. It's a sager NP8690 with a i7-940XM. Today I tried to slowly overclock it with throttle stop. Increased the TDP voltage to around 93/75. Then i proceeded to load test the thing for about 2-3 minutes. I was running a 25 Multiplier running at about 3.3ghz, temps were around 95-100C during the test. I then proceeded to shut the test down, after about a minute. BOOM. Computer went down, no more power and the charger started beeping. Pretty sure it indicated that the power is going back to the charger.

I then took the thing apart thinking that something was fried. I couldn't find the CMOS Battery, I did however pull the ram out and the hd out. Put it back together, left the battery out for about 2 hours. Tried plugging it back in, and as soon as I plug it in, the charger starts beeping. No lights are on, the power button does nothing. I also tried to do all of this without the battery, without success.

I'm wondering if it's time for a new laptop? Or is this fixable. Is the Voltage Regulator Module fried perhaps? If so, is it fixable?

Thanks for the help. Please reply promptly!

Have you tried to see if the cmos switch / battery is located under the keyboard? I would try to clear cmos first since the overclock seems to be the culprit of your troubles.

I can't seem to locate the CMOS anywhere on the board. And also can't seem to be able to take apart the keyboard, i tried prying a little and it seems as if i'm going to break the plastic. All the screws are out aswell.

It could be your lappys motherboard or the processor. Either of these two. I'm thinking that it's more of your lappys motherboard as processors still throttle down when they hit those high temps, whereas the mobos have to put up with more load, etc. It's just my sixth sense talking about it and some personal experience, however, I can't be sure.

Once your press the power button and if nothing lits up or if it lits up and goes of ASAP, then that's a bad mobo sign. As lappys mobos have really integrated components, it'll be hard to fix. I'll say a replacement under warranty or if not warranty then a new lappy or mobo for sure,

Give me 10 minutes i just downloaded the User manual from Sager, you can get it hereand look also to see where to clear the cmos.

Edit: Sorry I am unable to locate anything helpful in that manual, it's not like a IBM manual which has an entire breakdown of the laptop.

100 c seems really hot, but you said you aborted so that's good. I would never dream of overclocking a laptop because my personal experience is that they get too damn hot even stock! But more on topic, I've only replaced one cmos battery in a dell laptop and it was ridiculously hard to get to. Board and screen, along with everything else had to come out. I found a guide on google because it was a common problem with that machine, but if you can warranty it I would recommend that route if it's anything like that dell.

So what would pulling the CMOS battery do at this point? It wasn't a BIOS overclock, it was overclocked with ThrottleStop, so when the computer shuts down it goes back to normal settings. The CMOS battery woulnd't lock the whole thing up would it?

It should honestly just reset the bios. But as you OC'ed it through software, it should boot right back up to its stock settings.

Well, after fiddling with it for a few hours, 43 screws late I finally pulled the CMOS battery out, but without success. Still no power to the laptop, I'm thinking the motherboard is completely fried. I only had a 1 year warranty on this laptop unfortunately. It says 3 years labor, and 1 year parts which I have exceeded. I'm still going to try and call them, if not I will be getting a new laptop I suppose. Ivy bridge 3930 Here I come!
