Hi all,
I'm sorry for posting this issue here but who knows more about mechanical keyboards the GH community

A year ago I bought a Filco Majestouch keyboard which I've been pretty happy with. Though from the outset there was an issue I was having with it that at first didn't bother me. Recently since I started bringing my keyboard to and from work the problem became more apparent I would like to find a solution.
Basically, when plugging my keyboard into the PC whilst it is on and booted into windows, the keyboard puts the computer to sleep as if I had hit some kind of sleep button. More often than not, when I try to wake it from sleep the computer would start up but would not fully load to the login screen. I managed to work around this minor issue by going into the power options and changing "Choose what happens when the sleep button is pressed" to "Do Nothing". At that point I thought I was set and could continue on without worry. However after shutting down my computer and restarting with the keyboard plugged in the computer boots and then immediately enters sleep mode, attempting to wake it from sleep has the same effect as before yet this time it crashes and has trouble with consecutive reboots.
I don't have this issue with any other (lesser) keyboard I've tried and I also have the same problem with it at work.
This issue is also present on Windows 8 and 7 AFAIK
I have come here in the hopes that this is not a fault with my Filco as it may be difficult to return it (and I don't have to tell you how expensive these keyboards are!), perhaps there is some kind fix I don't know about or a firmware update I can grab, though I doubt it.
Any help would be appreciated, past experiences with similar issues would be good to hear.
Regards
