Kurt Hafner 1 Posted November 25, 2012 Have you updated to the a09 bios? If you had the i3 in it I'm betting your bios was really old and didn't support the XM CPU. Give that a try. Quote Share this post Link to post Share on other sites
svl7 5648 Posted November 25, 2012 The i3 CPUs got released several months after the i7, the 920xm has been running in the M15x since BIOS A00, it's not a bios compatibility problem.@OP: Make sure you locked the socket after inserting the CPU. Try a power drain. Quote Share this post Link to post Share on other sites
unclewebb 503 Posted November 25, 2012 Make sure you installed the heatsink properly too. It sounds like it is overheating so when you boot up, it reaches the thermal limit and your laptop reboots. Quote Share this post Link to post Share on other sites

bjokke 10 Posted November 26, 2012 Make sure you installed the heatsink properly too. It sounds like it is overheating so when you boot up, it reaches the thermal limit and your laptop reboots.I checked the temps in safe mode, core 1,2,3 and 4 are 70°c somethimes 60°cstrange is if I go to bios and see that the 920xm only recognized 4gb of my 8gb of ram:SI tried also to format the hdd but after the windows loading files I got a light black screen.I can only run safe mode.

iloveb00bs 874 Posted November 26, 2012 you tried the power drain trick with the coin battery taken out. its something i always do when doing component swap. Quote Share this post Link to post Share on other sites
James D 21 Posted November 26, 2012 Take off 2 RAM sticks. Try to turn laptop on then shut it off holding power button. Do power drain (unplug and hold power button for 5 seconds). Put ONE memory stick in slot 1 and try to turn it on.Please tell about your results.What I currently think is that it is smth with the memory. Try to find 2GB 1333Mhz RAM at home.What RAM do you have?? Quote Share this post Link to post Share on other sites

Brian 1975 Posted November 26, 2012 If all else fails, do a clean Windows install since you are able to get into safe mode. Quote Share this post Link to post Share on other sites

bjokke 10 Posted November 27, 2012 If all else fails, do a clean Windows install since you are able to get into safe mode.The usual way through f8 safe mode doesn´t work,I've done it with msconfig.Even in safe mode I can´t format. After press a button and the windows loading files it stuck with a black screen. Quote Share this post Link to post Share on other sites
James D 21 Posted November 28, 2012 Looks like CPU is DOA. Smth is wrong with memory controller I would say. Quote Share this post Link to post Share on other sites
eastbayrae 10 Posted December 25, 2012 Which 920 works in the m15x? I see many on eBay with different prices and different p/n's. Quote Share this post Link to post Share on other sites
Michael 1315 Posted December 25, 2012 Any 920 really, you must be seeing oem & qs/es chips. All of them will work. Quote Share this post Link to post Share on other sites

eastbayrae 10 Posted December 26, 2012 Thanks! I will add it to my upgrade list. I never knew how much this laptop can be upgraded. Quote Share this post Link to post Share on other sites
lyylove50 10 Posted December 26, 2012 Hi, I recall from other forum that M15x with i3 processor could come with two different motherboard, one is HM55 and the other is PM55. For PM55 there is no problem directly upgrade from i3 to i7. However with HM55, I remember it does not support i7. Could you check your motherboard and see which one you have.
