1. Battery Not Charging

One of the most frustrating problems is when your laptop battery refuses to charge. Here's how to troubleshoot this:

• Check the Power Adapter: Make sure the adapter is securely plugged into both the laptop and the wall outlet. Try a different outlet to rule out any power supply issues. Inspect the adapter cable for any visible damage. Ensure that the power adapter is the correct one for your model.
• Inspect the Charging Port: Look for any debris or damage in the charging port on the laptop. Use a toothpick or compressed air to gently clean the port. Do not use any metallic objects.
• Check Battery Health: In Windows, go to the Battery settings to check the battery's health. You might need to update the battery drivers. Look for any error messages related to the battery. If the battery is old or damaged, it might need to be replaced.
• BIOS Settings: Sometimes, the BIOS settings can affect charging. Restart your laptop and enter the BIOS setup (usually by pressing Del, F2, or F12 during startup). Check the power settings to ensure charging is enabled. Restore the BIOS to default settings if necessary.
• Contact ASUS Support: If none of the above steps work, it might be a hardware issue. Contact ASUS support for further assistance or a potential repair.

2. Slow Performance

Slow performance can be caused by various factors, but here's how to get your laptop back up to speed:

• Restart Your Laptop: This simple step often resolves temporary issues, such as software glitches or memory leaks.
• Check System Resources: Open Task Manager (Ctrl+Shift+Esc) to see which applications are consuming the most CPU, memory, and disk usage. Close unnecessary programs.
• Update Drivers: Outdated drivers can lead to performance issues. Update your graphics drivers, chipset drivers, and other essential drivers from the ASUS support website.
• Disk Space: Ensure you have enough free disk space on your storage drive. Delete unnecessary files and uninstall unused programs to free up space.

• Optimize Startup Programs: Disable unnecessary programs that start automatically when your laptop boots up. This can significantly reduce boot time and improve overall performance.
• Hardware Upgrade: If your laptop still feels slow, consider upgrading your RAM or replacing your hard drive with an SSD. This can provide a noticeable performance boost.
