AIDA64 LCD display freezes my pc since i enter power saving mode via non activity in Hardware monitoring Posted June 9, 2019 · Report reply Same problem here. ASUS P6T WS Pro with Logitech G19 keyboard. Meaning completely different chipset, different keyboard = same problem. If i turn PC Off in that case /by pressing power button for 7sec./ keyboard changes color randomly i.e. keys backlight became red /or any other random color/ and stays ON even when computer is Off. When i power ON the PC again keyboard obviously resets and color scheme returns to normal.
