I have a Dell Inspiron 14 7447, and there are a couple of niggly issues that have been bothering me since I bought the machine.
First of all, the touchpad fails to respond after I put the laptop to sleep. Rebooting is the only way to make it work again.
Also, there is a very strange problem with the mute hotkey. Trying to unmute or mute the system for the first time after a cold boot will cause the hotkey to register twice, i.e. when unmuting the windows unmute notification will pop up put then quickly flash to mute again. If I press this more than once it works perfectly fine, of course until I shut down the laptop and turn it on again.
Strangely enough, the issue doesn't arise if I choose to press the mute/unmute hotkey after a restart (not a shut down and power up). I've tried reformatting and reinstalling but nothing can solve the problem.
Any solutions to either of these problems>
