Hi, guys.My laptop's wireless suddenly stopped working.Also my bluetooth and FN buttons are disabled.While this happened I was online than connection got lost.I restarted my computer and there were no sign of WiFi.Than I formatted my laptop and still nothing.Now I am going to describe you this situation with photos to explain better.I would really appreciate if you can help me.Thanks by now.
If you already tried reformatting the PC, I would go ahead and make the assumption that it is hardware related. First, I would try opening the back cover of the laptop and removing the Wi-Fi card. (It looks like this: http/www.insidemylaptop.com/images/HP-Pavilion-dm4-base/disassemble-laptop-06.jpg). Remove the two connected cords, unscrew the card, remove it, dust the connectors off using compressed air (do this to the port as well). Then place the card back inside, remembering to re-attach the cords. If this does not work your Wi-Fi card is probably broken and needs to be replaced.
