To extend the battery life, reduce screen brightness, close unnecessary apps, and use power-saving settings. Regularly updating drivers and keeping the laptop on a hard surface for better ventilation can also help.
First, ensure the battery is charged by connecting the AC adapter. If it still doesn't turn on, perform a hard reset by removing the battery and power cable, then holding the power button for 15 seconds. Reconnect and try again.
Visit Dell's official website, find the support page for the Inspiron 5755, and download the latest BIOS update. Follow the provided instructions carefully to install the update.
Check for malware and remove unnecessary startup programs. Upgrading the RAM or replacing the hard drive with an SSD can significantly improve performance.
Ensure Wi-Fi is enabled and airplane mode is off. Update the wireless driver via Device Manager, and try restarting your router.
Turn off the laptop and remove the battery. Use compressed air to blow dust out of the vents. If necessary, open the laptop to access the fan for a more thorough cleaning.
Go to Settings > Update & Security > Recovery and select 'Get started' under Reset this PC. Choose to keep files or remove everything, then follow the on-screen instructions.
Overheating may be caused by dust buildup, blocked vents, or running resource-intensive programs. Ensure the laptop is on a flat surface for proper ventilation.
Use an HDMI cable to connect the external monitor to the laptop's HDMI port. Press Win+P to select the display mode, such as duplicate or extend.
Try restarting the laptop and checking for driver updates. If the problem persists, connect an external keyboard to determine if the issue is hardware-related.
