To perform a factory reset, restart your laptop and press F8 repeatedly until the Advanced Boot Options menu appears. Select Repair Your Computer, then Dell Factory Image Restore, and follow the on-screen instructions.
Ensure the power adapter is connected properly and the battery is charged. Try a different power outlet. If the issue persists, remove external devices and perform a hard reset by holding the power button for 15 seconds before trying to restart.
Reduce screen brightness, disable unnecessary background applications, and enable power-saving modes. Regularly update your operating system and drivers to ensure optimal performance.
Turn off the laptop and disconnect it from power. Use a can of compressed air to blow out debris and a soft, damp cloth to gently wipe the keys. Avoid using liquid cleaners directly on the keyboard.
First, power off the laptop and remove the battery. Unscrew the back panel to access the RAM slots. Carefully replace the existing RAM module with a compatible one, ensuring it's securely seated. Reassemble the laptop and restart it.
Check if the touchpad is disabled by pressing the function key (usually F3 or F9) with the touchpad icon. Update or reinstall the touchpad driver from the Device Manager. If the problem persists, contact Dell support.
Click on the network icon in the system tray, select the desired Wi-Fi network, and click Connect. Enter the network password if prompted. Ensure the wireless switch on your laptop is turned on.
Ensure the laptop is placed on a flat, hard surface for proper ventilation. Clean the air vents using compressed air. Consider using a cooling pad and ensure the BIOS and drivers are up to date.
Visit the Dell Support website, enter your laptop's service tag, and download the latest drivers. You can also use the Dell Update application pre-installed on your laptop to automatically check for updates.
Update the graphics driver through the Device Manager or Dell Support website. Adjust the screen refresh rate in the display settings. If flickering persists, it might be a hardware issue requiring professional repair.
