My dell inspiron 15 7559 wont shut off, the keyboard stopped working, the mouse and trackpad stopped working and the power button wont shut the computer off. Please advise on how to turn it off.
I suggest you contact Technical Support for assistance in the link below:
If Dell doesn't answer your question then I suggest you( or a very good friend) remove the battery, press the " Power On" button for 20 seconds, install battery,adapter, and then power on the system. Hopefully your computer function well now.
