MSI P45 Platinum doesn't wake after sleeping, hard reboot required
Hi guys, (first post here :))... I was highly impressed with some of the deeply technical answers on this site, so I'm hoping someone can help me narrow down to the cause of this issue I have, and possibly help me learn something about system software and firmware :)
So some time ago I acquired this MSI P45 platinum third-hand, and it has been living up to its name. However, it does not sleep and wake up properly.
To be specific, it looks like it sleeps properly, but doesn't wake up properly. The lights and fans start up, but one of 2 things happen
1) the POWER LED doesn't light up, only the HDD LED (strange)
2) the POWER LED lights up, the HDD LED doesn't work
Either way, no display. or any activity I can cause through the keyboard. I'm on BIOS 1.7b14(official Beta BIOS) (A7512IMS.17E). It didn't work with 1.6(official release) either. It doesn't seem to be any known bug.
I've tried a bunch of things, but I would like to try steps systematically once again, in case I've missed some combination. So, what could be the issue, and what can I check?
