Can not connect to WiFi, and WiFi is working properly.

Sometimes a WiFi card can become disabled. To check if the WiFi is not working solely on the device, connect another WiFi enabled the device to surround connections. If this works, the WiFi card may be disabled. To fix this, right click on the network button on the bottom right corner of the taskbar, next to the clock. Click Troubleshoot problems and let the troubleshooter detect if the WiFi Card is enabled or disabled. If it is disabled, it will ask you if you would like to enable the WiFi card. It will then test the network and asked if you are now connected to WiFi, if not, the card itself may need to be replaced.

Keyboard buttons are stuck pressed down or stuck up, missing, or buttons pressed but not responding.

When the keyboard is not responding or the buttons are stuck, something could be stuck under the buttons, or dust is preventing the buttons from responding, or something was spilled and stuck the buttons. Use a clean cloth or cotton swab to wipe the dirt or spill off the keyboard.

If after cleaning the keyboard and the buttons still do not respond or are stuck, there could be issues with the mechanisms used to keep the buttons able to be pressed and read by the computer determining what was pressed. Follow this guide to disassemble the keyboard and replace it with a new keyboard.

The screen stays black when the computer is turned on and fully charged.

If the screen won't turn on and the laptop is on, the screen may be faulty. When looking at the screen closely, if there is no display dimly lit then the screen will have to be replaced. To do this, follow this guide, How to Replace Dell Inspiron 15-5558 Screen.

When pressing the power button, the device shows no sign of responding or turning on.

If the device does not come on after pressing the power button, the battery could be dead. Connect the laptop to a charger and allow it charge for a while.

When the battery is inserted into the device, it could be in but not fully connected. In this guide, you will see how to connect the battery and make sure that it is completely connected and working.

If the battery is connected properly and the device still does not power on, the battery may have worn out. Batteries get old and stop holding the charge as well as they used to. To know if the battery is just old and not working properly anymore, plug the charger into the device and see if it powers on. If it does, the battery is the problem and needs to be replaced. Follow this guide to replace the battery.

When plugging in things to the USB drive, they won't connect or be recognized by the device.

Dust and other objects can get stuck into the USB port causing it not to work. To see if the problem is the USB port, connect a device to another USB port either in the same device or another device altogether. If a different USB port recognizes the device the problem is with your USB port. First, use compressed air or a small toothpick to get rid of any dust in the port. If this does not fix the issue, continue to check the wires of the port.

When starting up the device, the screen displays hard drive malfunction, hard disk corrupt, or frequently getting the Blue Screen of Death.

If the hard drive is corrupt and will not display anything saved to it or let anything new to be saved, it will have to be formatted. WARNING, this WILL delete ALL personal data saved on the drive. To do this, click the file button on the taskbar at the bottom, note: if it isn't there click the start button and "Computer," and right click on the drive needed to be formatted and click "Format." Let the process run and after it is done the hard drive should be working correctly. If not, the drive may need to be replaced.

If formatting the drive did not work, the drive may need to be replaced with a new one. Follow this guide to disassemble the device and remove the old hard drive and replace it with a new one. When doing this, if you have the operating system(Windows) on the old hard drive but can not access the drive by plugging in the new drive to the USB port via the cable provided with the drive, you may need to bring it to a professional to determine if the operating system can be transferred or a new one is needed.

If your device still freezes and you have corrupt files, it might be because you have a faulty RAM. RAM is an acronym for Random Access Memory and information stored on the RAM can be corrupted or lost. Follow this guide to disassemble the device and remove the old RAM and replace it with a new one.
