I have an Aspire A515-46 with windows 11. The backspace key type a lower case "s" and the "s" key backspaces and type the letter "s". I tried the on-screen keyboard and it behaves normally.
I also have set the region and keyboard to US with no effect. I loaded the trial ubuntu and got the same backspace and "s" issue. At that piont I thought it must be a faulty keyboard, so I replaced it.
The new keyboard is giving me the same issue with the backspace and "s" key.
The Bios is version 1.02.
Can anyone have a suggestion for this strange issue?
