Solved MSI P45 Platinum doesn't wake after sleeping, hard reboot required

[milindsmart]

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?

Hello Milind, and welcome to Seven Forums.

You might see if using the tutorial below to add AHCI Link Power Management to your power plan settings, and set it to HIPM+DIPM may help.

Hope this helps,

Gah this is frustrating

Just after I posted this, I slept the computer by mistake. And it woke up flawlessly!

I tried again now (morning) thinking it was a one off thing, but no... it sleeps and wakes up perfectly.

And I didn't even DO anything this time! Gah computers!

But yeah, thanks for that setting, looks very interesting. I'll update in a few days if this madness is really permanent.

Great news.

Yep sleep is working flawlessly since then. I guess this thread can be closed.

I'm glad to hear that it's still working without issue.
