This issue only occurs sometimes, it is not currently happening.
I first encountered this issue about a week ago.
Certain keys on the keyboard do not work, specifically:
I have tried reinstalling keyboard drivers through device manager, this did not solve anything.
I have dusted off my keyboard, it solved the issue for a few days, then came back yesterday. I dusted it off again, which solved it for a day, and it came back on startup today.
This is the third occurrence of this issue, and it always shows up at start up, not in the middle of usage.
I solved this occurrence of the issue after about half an hour, by just pressing keys and trying to use the computer as normal.
It wavered in and out of the three malfunction phases: perfectly working, failing to work whatsoever, and intermittently working.
When the issue is occurring, the specified keys all malfunction in unison:
if one works perfectly, they all work (with the exception of the ] key, which is actually not working at the moment, but was working when i began this post)
if one fails to work whatsoever, they all do not work
if one intermittently works, they all intermittently work
when it "intermittently" works, it works maybe 1-2 out of every 10 total presses. I just press it a lot of times until it starts working, or spits out a character.
This is the built-in laptop keyboard for a Lenovo Flex 2 or 3.
DxDiag can be provided if desired.
Does anyone have any ideas what this could be possibly be? Could it be a circuit board issue? A physical issue?
