First off I would like to say, I am pretty technical. I have assisted IT in my previous job and usually have no problems troubleshooting issues. I recently purchased this Dell laptop and I had this same problem and the laptop was brand new. I had to do a factory reset and then it stopped working. I could not even reinstall Windows as I had no internet. I went and purchased a ethernet dongle so I could have internet access and download the drivers. I downloaded and installed the drivers using Dell's software but it still would not turn on. It showed the Wi-Fi device active and working and showed up in Network Devices and in Device Manager but still would not turn on. It looks like it tries to turn on but flips off. There is no hard network switch on the laptop either.
