My Dell xps 15 laptop shuts down every 2 hours, exactly

I have this really strange recurring problem with my dell xps laptop, and it started with me sending it into repairs to replace the chipset, so I wonder if it has anything to do with that. My computer functions fine, it does not overclock or overheat at all according to the diagnostic tools I have checked, and is otherwise an extremely functional machine, aside from the fact that it crashes (no BSOD, no automatic restart, just sudden shut down with no warning, losing me all unsaved work) EXACTLY (this is the interesting part) every 2 hours. And when I say exactly 2 hours, I mean pretty much to the minute. Any process explorers I used inform me that there were no noticeable spikes around the time of the shut down (or should I say crash) and I have rigorously tested the battery pack and power cable to ensure this is not a power issue (which would make little sense anyway, with the crashes happening at precise 2 hour intervals). it could be running one chrome window, a video and a chrome window, or zero significant system processes at the two hour mark, the crash comes all the same. did a little research and apparently this is a common complaint for windows 7 RC systems in 2010 that have not been properly activated, hence windows activating the bi-hourly shutoff. Funny thing is I have windows 7 home premium, an activated and completely legal version, which has been functioning well for 3 years until this time. it really is getting sort of maddening, and my laptop repair place just basically told me they have no idea what's going on, so I'm desperate, and as far as the internet tells me, this is an obscure windows activation problem that hasn't been a serious issue for people since 2011. any ideas? Thanks in advance!

thanks layback bear! (also thanks for not telling me to check my battery) the general consensus among my techie friends seems to be a mobo incompatibility, so I sent it back and another repair place has suggested they can install a better chipset in about two days. I shall inform you of the result.

sorry it took me some time, got my new-new chipsetted laptop back from the shop, (afraid it was an unlicensed dealer, generally cheaper because my warranty's expired, and thankfully they fully refunded me when the problem didn't go away) didn't fix it, installed ubuntu briefly, didn't fix it, performed a clean windows 7 hp install, didn't fix it, so I am nearing the end of my rope (not with anyone here of course, just my darn machine). reactivation didn't work either, but for all it's worth, here's minitoolbox logs of the last couple of hours; the computer shut down unexpectedly AGAIN on the two hour mark at a little bit before 9.25pm, and true enough there is some interesting jiggery pokery going on there. any idea what it could mean?
