This litle problem has just presented itself a few days ago.
While the keyboard (G15, 2nd revision) seems to be functioning normally during use, when I come to shutdown my computer, something odd happens. The backlight (keys and the LCD) will remain on and flicker until either the computer is started up again, or the power supply disconnected. A few times now I've shut the computer down and night and returned in the morning to see the keyboard all flickering.
I wonder if the hardware is failing and something is going to go wrong soon.. Like I said, it has only just started happening recently, and I can't think of any changes I've made since. No new hardware or anything.
OS: Windows XP Pro (32bit)
CPU: Intel Quad i5 750
GFX: ATi Radeon 4850
RAM: 4GB DDR3
Motherboard: Gigabyte P55-UD3

I'm having this exact same problem. It's fine when it goes to sleep but whenever I shutdown the only way to get the flickering to go away is to unplug the keyboard or shut the power off to the computer, both of which are extremely annoying.
If you've had any luck solving this problem please let me know what you did.

You could do some testing if you have another PC handy or parts.
I would look to the motherboard and psu.
Motherboard = another PC. This is the easist way to test with a different mobo. Or ask a friend relative to try it with theirs.
PSU = new or different psu preferably one with more wattage, but equal to would suffice for testing.
Otherwise, imo its a problem with the keyboard...
Still the mobo could need a bios update or maybe its a windows bug.
But, its faster to test yourself sometimes. And If you google it and no answer is found then test test test and you'll find out what you need to do.

Same here, but my G510 flicker in DOS or some Acronis Bood applications and can't do anything.
Logitech plz release a newer Firmware (fixed). I tryed 3 motherboards and my G510 keeps flickering on all of them. So it's definetly a problem in device software (Firmware)
