Hey folks,
so since today the following keys of my laptop stopped working(got a german layout):

• 1
• Q
• A
• Y
• Shift(left and right)
• ^
• Tab
• CTRL(left and right)
• Alt
• Alt+Gr
• DownArrowKey
• ESC
• Delete
• F11
• Print
• And that middle trackpad button

Here is a picture of my keyboard.

It seems the problem is not windows specific. When i boot into Manjaro (a Linux distro) the problem still persists.
Nevertheless i updated all drivers and BIOS but it didnt work. When i connect an external keyboard, all keys of the external worked.
What I did yesterday was working with eagle (electronics software to make schematics and layouts) and
I connected a mouse to it that i didnt connect before. (uninstalling mouse/keyboard drivers didnt help)
This is what I used to check the keys: testkey
Thanks in advance!

Sounds like you need to try another keyboard if an external one works fine and the laptop one does not in all situations. If that does not help, issue is with motherboard connection.
