I have already had this laptop for about 6 years. I have never been more satisfied than this laptop. I have never encountered any problems before this:
Press Ctrl (left), Alt (left), "W", "x", and "c" will stop working in just 5 minutes, then work again, but the "FN" button will never work.
I have tested in the .txt file, the file will not work properly when "error" occurs.
I tried to delete the native keyboard driver and let Windows reinstall them: did not change.
If someone has encountered the same problem, if you can lead me to solve this annoying "bug" (such as "W", "x" and "c"), I will not be grateful.
If it is related to a serious fault, such as the keyboard strip cable is damaged, is it worth sending my 3810 laptop to the maintenance center? Although it doesn't spend time and money.
