I have replaced the intern 256GB M.2 SSD with a 1TB M.2 SSD.
I used the attached instruction from Acer.
After closing the lower case and rebuild the Operating system the keyboard will not work partially. Some keys work, some not.
I've opened it a second time and made it again - same error.
I've changed back the original SSD - same error.
What can I do? There's nothing with the keyboard on the backside, what I could have broken.
Thanks for help!
