Dell XPS 15 9550 Wake-On USB kills Motherboard

Hey everyone,

I have the XPS 15 9550. I enabled wake-on usb in the BIOS (flashed the latest one). When I tried to waken up the laptop with my keyboard, the laptop froze and I only saw rainbow-like pixels. I called Dell support and they swapped the motherboard. With the new motherboard, I re-enabled wake-on usb. Again, when waking up, the laptop froze and crashed. Upon restart, I noticed that I cannot see the Dell boot logo anymore. I only see a message stating that Windows did not load correctly. If I press F12, I see the menu to choose BIOS, but when I click on it, I cannot enter the BIOS but instead the laptop restarts and I get a black screen. I again called customer support, they swapped the motherboard again, which was today. I re-enabled wake-on usb, and the exact same problem ocurred (i.e. Dell Logo not visible anymore and I cannot boot into windows anymore nor access the BIOS). I used the same set of USB devices on another laptop and it works like a charm (i.e. does not kill the laptop and wakes it up when asleep). I can only recommend everyone not to enable wake-on-usb!
Did anyone else have the same issue? If yes, is there a way to fix it ?

Cheers!

 

Report it to dell as the twats on the phone don't have the brains to put 3 & 3 together, and ffs don't do it to a 4th laptop until they release a BIOS fix.
