The wifi will not connect or won’t stay connected.
First, try resetting the router to make sure there is nothing wrong with your internet connection. If the problem continues, either update your laptop programming or go to the Intel website and download the latest update/software for your laptop model.
Check that the router configuration and the configuration on your laptop match. If this does not improve the connection, try finding alternative channels. Channels 1, 6, and 11 are some of the most receptive wifi channels.
Depending on where you are, radio signals can cause the wifi signal to fail to connect or weaken. Try moving somewhere that does not have too much exposure to radio signals.
Laptop antennas are usually hidden within the laptop itself. Most antennas are positioned against the edge of the screen. To test the signal, manipulate the position of the antenna by turning the screen vertically or horizontally, or follow the instructions of this guide. The change in position should strengthen the signal.
When the device is plugged in, the battery does not charge.

The touchpad does not move the mouse or click properly.
If the touchpad is not responding, check to see if the touchpad driver is installed correctly through the settings. Open settings and locate the folder “Samsung Update,” then find “Touchpad Driver” to make sure the touchpad is installed. If the touchpad is installed, the word “installed” will show in the bottom right corner of the settings page.
If an external mouse has been connected to your laptop, your touchpad may have been disabled. Open settings and select “Devices”, then locate the touchpad options. Click the touchpad tab and find its settings. Once doing so, check to see if the box “disable when external point device is attached” is checked. If so, uncheck it.
Your touchpad may have been disconnected from the motherboard of your laptop. This will be a case of operating on your own device. Refer to this guide for the steps involved.
Computer dies quickly after it has been charged.
If you tried different charging cables and went through the battery settings, it’s time to get a new battery. Follow this guide to find out how to remove your old battery and install a new one.
Replacing the battery would fix the problem, but if you can’t afford a new battery at the moment, a temporary solution would be using your laptop without it. Just remove the battery and plug in your laptop like you would normally.
If you tried multiple power cords and already replaced a battery, your laptop may have a problem with internal charging circuitry. Replacing the charging circuitry has to be done by a professional.
Keys on the keyboard are not always responsive.
Try restarting the computer; this might reboot the driver software for the keyboard. If this does not work, the keyboard driver software may need to be reinstalled. To do this try opening settings, or searching online for the necessary keyboard driver software for this model of the computer.
Try opening the settings for the keyboard and adjusting them. If the hot keys do not work, you might have to reset them. If the settings for the computer are not on the home screen, search for them in the computer’s finder. To fix the hot keys, try opening settings and changing or updating the settings for the hotkeys, or “function keys.”
If the keys do not raise back up after being pressed down, try cleaning the keyboard with an alcohol wipe. If they continue to stick and jam, the keyboard may have to be replaced. If you do not already know how to do this, please refer to this guide for instructions.
