Laptops

To be of assistance you need to provide a few details about your problem computer...is it a laptop, desktop? What is the brand, make and model, and how old is it? What operating system does it run, like Windows, ChromeOS? Depending on these factors it is possible a simple keypress could solve the issue, but without it there is no way of knowing which key. It could also be a hardware problem such as a WiFi or ethernet adapter failing.
