Thinkpad W520 won't turn on [+pics]

Windows didn't bark at the new motherboard, so no activation issues. The downtime also seems to finally have triggered the 'maximum lifespan mode' of the battery.

I netted three screws from this adventure, the one that was stuck on the I/O daughter board and one long case screw. Apparently I put one short screw inside in the wrong hole there (near RJ-45), so now the long one doesn't fit. There were no threads in the hole the small one was supposed to go.

And also one short screw that I had in the bucket of case screws. I couldn't find where that one had to go, lol. The other three short ones sit under the battery, the fourth?

Anyway, I'm happy it's back up and running, so for now I'm happy and I'm not going to take it apart again.

Haha, BIOS 1.16 also means the RAM is running at 1600

FYI: every removable screw, with its location, is pictured and described in the HMM, Chapter 9.

Now it randomly refuses to resume from sleep. It powers up with all the lights etc., but then shuts down a few seconds later with a loud "clunk" [and repeat]. Pulling the battery and pressing the power button for a few seconds solves that problem. So far it's three times this week out of probably 40 times I resumed it from sleep.

If only that would exist

EDIT: Might be a BIOS issue. Will update this weekend.
