Yep replaced screen on my HP Spectre X360 and found I had same problem with keyboard and touchpad.

I was fooling around and just couldn't figure out what changed besides my screen that I replaced. The post about the gyro chip just didn't sound right to me.

I could see how 3 or 4 days with the thang tore down and battery unplugged might just cause some glitch.

I got one of these early around 2015 15.6" screen with the 3840 X 2160 screen 15-bl012dx. It just all of a sudden about 2" on left side of screen started dragging down the icons to just long streaks back in 2018. I remembered I had paid $1500 for the stupid thing and hadn't fooled with it in several years because of screen and almost chunked it in the trash several different times.

I jumped back into it last week found a screen for $165 and ordered it.

Well I saved it and it was working, the screen that is. That's how I found these posts.

What I discovered was somewhere a driver must have gotten screwed up because after I got it back together and sitting up like a Laptop the screen flipped upside down and had to fool with settings to get that straight. That's like flying a remote control plane back to you where controls are backwards, quite a feat.

Then I concentrated on starting out with the BIOS just like the other people were saying and as they did found Keyboard, and keyboard lights all worked while in bios setup.

I just couldn't buy the Gyro Chip problem, as it was working last week and all I did was unplug battery and spend about 5 hours tearing out the screen with a sledge hammer. I wasn't even in the bottom of the computer.

To make a very long story short, I blew a fresh Win 10 on it from my Media Creation USB and didn't reset it with the Win 10 that was on hard drive.

After install, I started the dreaded updates, and got all the way to May H2o 2021 update and everything, including the keyboard and the touchpad worked as expected.

Then of course windows had a sackful of "Optional Updates from Intel/Hp etc... so I went ahead and put all of them on also. Well somewhere in those optional updates  there was a driver that blew up the keyboard and touchpad just as before.

So I reinstalled windows 10 and did all the Windows updates "But No" optional updates and everything is working as it should. I knew when the boot up to BIOS the keyboard was lit up and after loading windows it was dead, no type, no lights, so I knew it had to be drivers.

Hope this info might help someone else.

Hi,

Thanks for sharing. It could be helpful for some other Member in the future.

Do you know what the specific driver was that Microsoft offered as an optional install. 

Take care,

David

It was a very long list of drivers, I had to take two screenshots and patch then together. I was almost paranoid to go back to updates and click on the "Optional Updates" button.

Optional updates
Driver updates
If you have a specific problem, one of these drivers might help. Otherwise, automatic updates will keep your drivers up to date.
