I just recently bought a W540 and have the same wake up issue. Most solutions suggest to install an old Intel GPU driver, however the old driver is either missing or won't install on Windows 10. I tried the oldest driver that supports Windows 10 and the issue presists.
I also cannot find nvidia graphic card in Device Manager. I also tried lspci in Ubuntu but the result is same.
It seems that some people fix the wake up problem with a motherboard replacement. If there is no software solution to those 2 issues I have to go this way. I'd like to know if I can install W541's motherboard in W540's chassis. They look very similar and use the same hmm.

If you recently bought it, can it be returned? My guess is that the previous owner put a T540p motherboard with intel graphics onto a W540 case. (that will fit) A W540 board would have 4 memory slots. Is that what you have?
I haven't tried a w541 MB in a W540, but I would guess that it would fit.
