Recurring keyboard debounce(?) issue - missing keystrokes

I have a Dell Precision 5510 (identical to the XPS 9550) running Windows 10, and in the last few days, there have been 3 mornings that the computer woke up with a frustrating keyboard issue: the keyboard doesn't lag, but it does miss keystrokes. For example, if I press any key 6 times fast, only 3 strokes are registered. Or if I type text at normal speed, it comes out like this: tex typed at norml sped . If I type slowly, everything comes through fine. The issue persists when I restart in safe mode, or even when I reboot to BIOS. But eventually I have gotten the keyboard to work after shutting
