Hello my laptop's keyboard keys aren't working properly. I need to hold the key for 2-3 seconds before it gets detected.
I tried disabling the filters but still nothing.

On starting, there is a warning that the fan is mulfunctioning. Several technicians have tried to replace the fan in vain. They have also looked at the bios, certain drivers etc in vain. What could be the problem?
