Hi,
I have a Dell XP 9570 i9 (HD) which I've only had for a couple of weeks. Apart from not waking from sleep which I've managed to cure I have terrible lag with my external USB keyboard and mouse. Initially I thought it might be the StarTech dock I was using but some testing has led me to believe it is a hardware/software issue with the Laptop.
The symptom is that as I type for a few seconds it will be fine and then it starts to lag and then it repeats keys. Eventually it settles down and then the issue starts again.
I have tried:
I'm not sure where else to go with this, but given that I know my docks work with other Laptops/PCs with the same keyboard(s) it MUST be related to the laptop software orhardware.
When you have access to important data a repeating delete key can be disasterous.
Thanks,
LJ.
Solved! Go to Solution.
They just replaced my motherboard on my 9570 and still having issues with usb keyboard/mouse with lagging/repeating etc
I just had to do disable the c-state (I am also on the latest bios 1.15)
