I have problems with my W500. It sometimes boots, and sometimes not.
It literally is random, and I have no idea why.
The times it doesn't boot, it hangs right after the press on the power button, when the "Lenovo Thinkpad" screen appears. It just does nothing.
It doesn't react on keyboard presses. I waited on this screen sometimes for hours.
If I am lucky after several minutes it finally boots. Sometimes it boots right away, without problems.
The BIOS software got updated by me yesterday, but it didn't change the problem. There are no devices connected to the Thinkpad that could cause that problem (no usb drives, no network cable, ...).
The USB ports seem to be fine (this is one of the solutions that people are given when encountering my problem).
I hope someone can give me recommendations on what do do or what could be broken.
Thanks in advance,

you're right, I'm not trying to do something unusual, it's a normal boot without any abnormalties.
The removal of the optical drive didn't result in solving the problem (would be funny though), and unfortunally I can't get into the BIOS because the device doesn't react when pressing keys on the keyboard.
You said "It's probably _just_ a motherboard problem", but isn't that the worst that could happen? I mean something like a broken RAM you could easilly replace, but a motherboard is kind of stressful and expensive. Sorry if I am missunderstanding you!
Really? The internal keyboard etc. get's recognized as USB devices? That's interesting!

The internal keyboard should be PS/2.
Are there any damaged USB ports? Or rather, anything stuck in any USB ports that could spontaneously bridge contacts?

I did several times, this should not be the problem, unfortunally. :/
Also, the times it does work, the keyboard also did (I don't know if that means that the keyboard isn't the problem).

I tried that, and without RAM sticks inside it doesn't even show anything on the screen, not even a beep sequence.
What's kind of weird is that when I tried it yesterday, the Thinkpad booted (I tried 2 times to be sure).
I thought that might be the solution (to reseat the RAM), but today it doesn't work anymore.
It seems like every time I screw the screws back in and reassemble my Thinkpad, it doesn't boot anymore. But I don't screw them in like a wrestler or something, I am careful. I don't think this has anything to do with it, but I just wanted to leave it here.
Might aswell just stop working after couple of hours (in my case half-a-day).
