Lenovo ThinkCentre Edge 92z does not power on. At all.
Last week I turned it on, started Steam, walked into another room, and came back to find a black screen, no fan, no power to anything, no effect from power button. For a day or so I optimistically tried the power button every time I walk past, to no avail. Have already done troubleshooting on the following, which check out fine: outlet, power strip (not using anymore for testing), power cord (pulled from another Lenovo PC which is working perfectly). The power button is on the bezel of the screen; it's not a switch.
Some more info: Machine type 3414. Got it in Sept 2013 new from an online dealer, my warranty expired in April 2014. I boot to and run OS (Windows 7 64) and most other things from an mSATA SSD -- I installed it within the first month of having the computer, so virtually the whole time I've had this same config. Have not upgraded memory, graphics, optical or any other thing. Everything else is stock, so I didn't think I was taxing the PSU at all. (AcBel 180W switching power supply: apparently only comes in these sorts of Lenovos). I ordered a $20 used one from eBay that should arrive in a few days because I figured between a $15 PSU tester and $20 PSU I'd rather cut to the chase. If that doesn't fix it, my next likely suspect is the mobo, right?
It's not a classic PSU failure from what I've read: there were no progressive errors, no shuddering/BSoDs/random on-off cycles. Just catastrophic. There's no weird little sounds, no light on the mobo, no shudder from a fan trying to start up, just cold dead silent dark nothing.
I would like to believe I can fix this myself, but I'm not sure what the most reasonable next step would be. I've looked around for replacement motherboards and they only come as refurbs in the $500 - $1100 range. That's bonkers. I'd build a whole new computer first (and will be building a new desktop if it comes to it).
Again, I know that most "fails to power on" issues are because something's not actually connected to power -- that's not the case here. I hope there's someone with more experience who actually knows something about this (although I hope this hasn't happened to others, it's quite discouraging).
This experience has totally ruined AIOs for me; I just can't fathom why each part has to be proprietary and impossible and just completely un-fixable.
I have pictures of what the parts I've addressed so far look like, in case my overly long description of the problem doesn't suffice. I also have Lenovo part numbers. Not that I can do anything with them...
