How to reset the BIOS in new Alienware 17 with out entering bios cause I just can't open it.

My issue is how to reset the BIOS in new Alienware 17 with out entering bios.
Why? Because I just can't open it...
I set overclocking setting with BIOS and intel XTU, and after I restart it, there were noting on my screen, not even warning.
I guess maybe it will be fixed after I reset the BIOS setting. But How? I don't want to open my computer to pull out the CMOS battery cause it cost lot of time.
Can anyone give me some help please?

 

You have to Unplug the laptop, open the bottom, remove the battery, hold power button down for 10 seconds, then remove bios battery (press the power button again for good measure) then reinstall bios battery and laptop battery + put back together and restart laptop.

(just a random CMOS battery pic, might be a different color but should be very similar to this)


There is another way, to load a flashing program onto an USB and re-flash the BIOS, which is much more dangerous for the Laptop, and shouldn't be done by inexperienced user

If resetting or Re-flashing the bios doesn't solve your problem, call AW

 

The bios battery is located just above the left corner of the cpu socket. You can actually lift the bios battery slightly without actually taking the chases apart. Simply grab a plastic pry tool of some sort, gently lift the back end of the battery off it's contact pins. Now remove your ram modules and start your computer. Your computer will beep around 5-7 times. Your computer will then restart. Whiles it's restarting, quickly plug 1 of your ram modules back into it's slot. Your computer should now display your loading screen. Power down your computer as soon as you get the chance to. Hook your ram module up and seat the bios battery. Close up.. enjoy.

 

Problem with this scenario is if all 4 ram slots are used, Dont you need to remove ALL the ram. I just did this the other night.. ( bad over clock) i can also verify that the jumper points on the mother board only do a soft reset, not a hard reset, do the long way you must.

 

So what if i'm using all four RAM modules? Should i take them all? And, I just heard that there's some kind of "key combination" could reset BIOS without entering it. Have you heard of that?

 

I had to take off the palm rest, its not that hard, and I took out all the ram modules, it worked like a charm, i haven't heard about the key combo...

 

So do I have to use AC power all the time?
And also, I heard from another BBS that the second way won't work.

 

Yeah unfortunately.

 

Well, I have to remove everything on the back to remove the palm rest and the RAM modules, and it just won't restart if I don't put all the fans and the heat sinks back. One of the copper wire on status-light board cable is now almost fall off from it after lots of installation and re-installation.

 

That's a bad news for me...
But still, thanks for helping me.
I hope one day that there will be an AW bios support changing core voltage....

 

Huh? You can change the core voltage as far as I'm aware.

 

Huh? I've not been able to do that on my M17x R4 and not seen that on the new M17...

 

I'll take a look later if I get a chance. I'm almost certain I've seen the setting for that which isn't greyed out.

 

The Sandy Bridge and Ivy Bridge CPUs do not have a setting to directly alter core voltage. You can add 'Additional Turbo Voltage' (and must do so if you are overclocking).

You can change core voltage with XTU or ThrottleStop. Try using XTU to change your Core Voltage to Static (versus Adaptive). Reboot and see if an additional setting for core voltage appears in the BIOS underneath the multipliers.
