    Hey all! Please clarify an issue.

    Ive become pretty good at disassembling and re-assembling my M17X R2 and have it working reasonably well.

    So I bought a 920XM from China and disassembled the laptop, used a little screw driver to unlock my 720QM, removed the 720QM, placed in the new 920XM, locked in new 920XM, placed on kapton tape and appropriate grease, then reassembled. I turned on the unit, and nothing but the usual keyboard backlights and fan spin and spin.

    I got a refund which was very reasonable, and bought a 940XM from a US seller. I repeated the install process exactly and got the same result.

    I should add that when i follow these steps and return my 720QM, it fully boots into windows and ive just typed this thread on it.

    I should also add Ive been using the A10 Bios, and Ive noticed that when the laptop successfully posts, the DVD clicks as it turns on. I have come to recognize this click as a happy POST beep.

    I think its a bad chip. The US seller is refusing a return and insists on a poor partial refund.

    More importantly he insists that it was working for him, and blames my Bios for having a locked TDP. Im aware that there are A10 unlocked bioses for overclocking, but shouldnt the standard A10 boot? I read on this forum somewhere that it should.

    Ill give it a try after an update, but i still think hes wrong. Personally i'd be happy to be wrong myself because I want this chip to work of course!

    Anyone with experience in an XM install please clarify this for me! I tried doing a CMOS clear as well with same effect.

    Locked TDP has nothing to do with a XM chip not working. It was offered from the factory in the M17x R2, with all sorts of BIOS versions. You really don't need the kapton tape unless you are using liquid metal and want some sort of an insurance policy. The chip drops right in, turn the screw, attach the heatsink and power on. There is no magic involved with CPU upgrades.

    Since I have your attention, once I do find a working XM, should I even mess with the unlocked BIOS? I think just having the standard A10 on an XM provides multiplier OC which is all thats necessary.

    Ive only glanced at the custom BIOS but it looks painful to me. Of course I can do it, but I feel hesitant.

    The unlocked BIOS provides nothing useful on M17x R2. Stock BIOS is perfectly fine and you can do all the performance enhancements with throttlestop

    In the off chance that someone else faces this issue in the future...

    ***Update***
    There is no complication involved in the processor upgrade from a 720qm to a 920/940XM.

    I had to get ebay involved to return the defective 940XM but I got my money back. The seller was not at all happy about it and still maintains that it works in his Acer.

    I suppose its possible but I doubt it... the replacement 920XM booted right up and seemed quite happy to have a new home. It seemed to idle at 55C, but jumped up to 80C under just a mild load! Thats a little scary for me. Now I have to read the OC posts in this forum and decide how to configure.
