I have recently had the motherboard of my laptop replaced under warranty, and since receiving it back the backslash key is not working correctly (having previously worked). I tested the key using the onscreen keyboard, and the key itself works, but functions as a shortcut for the control button instead of backslash. It is possible that I may have accidently pressed another key that reassigned it, but I don't remember doing so. How can I fix this so that the backslash key works properly again? (For reference, I am using the UK QWERTY keyboard format.)
I have to admit though, I am not very impressed with HP, given that I spent ~£1500 on the HP Spectre 360 less than a year ago, and already I have had several problems with it - the screen stopped working (required the motherboard to be replaced), and then the backslash key being incorrectly assigned. The warranty is only for a year (which for me runs out in 2 weeks). I shall be extremely disappointed with HP if anything further happens to my laptop soon after the warranty runs out. To be honest, I expected a lot more reliability from such a high end laptop.
