Ensure the laptop is plugged in and the power adapter is working. Try a hard reset by removing the battery and power cable, then holding the power button for 15 seconds. Reconnect the power and try turning it on again.
To improve battery life, reduce screen brightness, disable unnecessary background applications, and activate battery saver mode. Regularly updating your BIOS and drivers can also help optimize battery performance.
First, power down the laptop and disconnect all cables. Remove the back cover by unscrewing the screws. Locate the RAM slots and carefully insert the new RAM module. Reattach the cover and power on the laptop to verify the upgrade.
Use an HDMI cable to connect the laptop to the monitor. Go to Display Settings by right-clicking the desktop and select 'Extend' or 'Duplicate' to configure the display settings according to your needs.
Restart the laptop and check if the keyboard responds. If not, try connecting an external keyboard to test for driver issues. Updating or reinstalling the keyboard driver through Device Manager may resolve the problem.
To perform a factory reset, go to Settings > Update & Security > Recovery and select 'Get Started' under Reset this PC. Choose the option to remove everything for a complete reset. Remember to back up your data before proceeding.
Regularly clean the keyboard and screen, ensure ventilation ports are dust-free, update software and drivers consistently, and perform regular system scans to maintain optimal performance.
Restart the laptop and router. Ensure Wi-Fi is enabled and airplane mode is off. Update the Wi-Fi driver in Device Manager. If problems persist, try resetting network settings via Settings > Network & Internet.
Ensure the laptop is on a hard, flat surface to allow proper ventilation. Clean the air vents with compressed air to remove dust. Consider using a cooling pad, and check for any background processes consuming high CPU resources.
