The laptop does not gain charge when plugged in.

If the device is not charging while plugged in, there could be a problem with the power cord. Make sure that the power cord is fully plugged into the outlet and ensure that it is not loose.

Check to see if the Wi-Fi on the laptop has been turned off. To do this, locate the Wi-Fi button. The Wi-Fi button looks like a radio tower and is located next to the mute button.

If not, it has been powered off and needs to be powered on.

If your laptop is still unable to locate available Wi-Fi networks after attempting the above steps, the Wi-Fi card module inside the computer is broken or defective. Follow this guide to replace the Wi-Fi card.
