JackE said:If you game on the machine, what games are you playing?
JackE said:>>>There are periods where the keys work pretty much flawlessly.>>>Not busted. Maybe games are not letting go of remapped functionality till a cold boot happens. Try turning off fast startup in ControlPanel's power button app. Then shut Windows down normally. Turn it back on. Then give the keyboard a test workout at this link to see what happens before you get into any game playing.
JackE said:>>>repeated strokes just come and go as they please>>>Any key? Or just the game keys? If only the game keys, check Task Manager processes and apps that may be running in the background. automatically loaded on startup, that may be related to any of the games even though you might not be playing them at the moment.
JackE said:>>>although only really seem to get triggered when using "D" key. Also looks like that's affecting the Tab button more than the W one>>>>>>Only the W and Tab key.>>>These seem like conflicting statements? Please explain.
JackE said:>>>Often when hitting the key, it will recognize it as multiple (2-5) keystrokes instead of one, or stutter when holding the key down.>>>OK. When you momentarily 'press & release' a key, you often get multiple keystrokes. And when you 'press & hold' a key, you get stuttering. What is the difference is between multiple keystrokes and stuttering?
JackE said:>>>Exactly. By now, I'd assume that the stuttering and multiple keystrokes stem from the same cause.>>>What I'm trying to get at is please define your meaning of the words 'stuttering' vs 'multiple keystrokes'. The reason I ask is that pressing & holding any key results in multiple keystrokes on any keyboard for as long as you hold the key. If multiple keystrokes has the same meaning as stuttering for you, then this is completely normal 'press & hold' behavior. The momentary press & release behavior you describe is not normal when it results in multiple keystrokes but can likely be adjusted in keystroke timing properties.
JackE said:>>>On the key tester website>>>Pressing the key once would sometimes cause the key to light up multiple times>>>typing something with a "w" fast (like "windows") it would often omit the second "w">>>When holding down the key it would blink rapidly and irregularly instead of appearing as being pressed continuously.>>>(1) What happens when you do these things in simple texting apps like notepad? If, for example, does pressing & holding the W key show a sequence of Ws but displays each W in an erratic vs smoothly progressive fashion? If erratic, this might suggest that either background process(s) are also consuming a lot of CPU time or some of the CPU cores aren't being used.(2) Why would you need to the press D key and Tab key (or W key) at the same time instead of sequentially? Are D+Tab and D+W special hotkey combos or shortcuts needed used in some games or apps that you're using? Or just a chance observation?
JackE said:>>>The day those problems started occurring, I joined the Windows Insider Program.>>>I did a clean install of windows just yesterday and left the program.>>>Was the clean install the Microsoft-generic Win10 using the media creation tool or the ACER-specific Win10 using the ALT+F10 cold boot method from ACER hidden reset partition?
