To perform a factory reset on your Dell Inspiron 5545, restart your laptop and press F8 repeatedly to enter the Advanced Boot Options menu. Select 'Repair Your Computer', then choose 'Dell Factory Image Restore'. Follow the on-screen instructions to complete the reset.
First, ensure the laptop is connected to a power source. Try performing a hard reset by removing the battery and AC adapter, then pressing and holding the power button for 15 seconds. Reconnect the power sources and try turning the laptop on again.
Visit the Dell Support website and enter your laptop's service tag. Download the latest BIOS update and run the executable file. Follow the on-screen instructions to complete the update process. Ensure your laptop is plugged in during the update.
Overheating can be caused by dust buildup or inadequate ventilation. Clean the air vents using compressed air. Ensure the laptop is on a hard, flat surface to promote airflow. Consider using a cooling pad to help manage temperatures.
Turn off your laptop and remove the battery. Unscrew the back panel to access the hard drive. Carefully disconnect and remove the existing hard drive. Insert the new hard drive, reconnect it, and secure it with screws. Replace the back panel and battery.
Ensure the touchpad is enabled by pressing the F3 key or using the function key combination (Fn + F3) if applicable. Check for driver updates in Device Manager under 'Mice and other pointing devices'. Reinstall the touchpad driver if necessary.
Reduce screen brightness, disable unnecessary background applications, and use the 'Power Saver' mode. Regularly calibrate the battery by fully charging and discharging it once a month. Unplug peripherals when not in use to conserve power.
Remove unused programs and disable startup applications via Task Manager. Perform a disk cleanup and defragmentation. Consider upgrading the RAM or switching to an SSD for faster performance. Regularly check for malware using antivirus software.
Click on the network icon in the system tray and select the desired Wi-Fi network from the list. Enter the network password if prompted. Ensure the Wi-Fi is enabled by checking the wireless switch or function key (usually Fn + F2).
Check for driver updates for the graphics card in Device Manager. Adjust the screen refresh rate by going to Display Settings. If the issue persists, connect the laptop to an external monitor to check for hardware issues.
