૩.૩. બંધ કરી રહ્યા છીએ

To safely shut down your Raspberry Pi, click the Raspberry Pi icon in the top-left corner of the screen, then select શટડાઉન. Always shut down the system properly before disconnecting power to prevent data corruption on the microSD card.

6. જાળવણી

• સૉફ્ટવેર અપડેટ્સ: Regularly update your operating system and installed software to ensure optimal performance and security. This can typically be done via the terminal using commands like sudo apt update અને sudo apt full-upgrade.
• ઠંડક: The Raspberry Pi 4 can generate heat under heavy load. Consider using a heatsink or a fan case to ensure proper cooling and prevent thermal throttling, especially for demanding applications.
• પાવર સપ્લાય: Use a high-quality 5V/3A USB-C power supply to ensure stable operation. Insufficient power can lead to instability.
• માઇક્રોએસડી કાર્ડ કેર: Avoid frequently writing large amounts of data to the microSD card to prolong its lifespan. Consider using a USB SSD for heavy data operations.

7. મુશ્કેલીનિવારણ

• કોઈ ડિસ્પ્લે આઉટપુટ નથી: Ensure micro-HDMI cables are securely connected and your monitor is set to the correct input. Try a different micro-HDMI port or cable.
• પાવર એલઇડી ફ્લેશિંગ: This often indicates an insufficient power supply. Ensure you are using a 5V/3A USB-C power supply.
• વાઇ-ફાઇ/બ્લુટુથ સમસ્યાઓ: Check your network settings in the Raspberry Pi OS. Ensure the device is within range of your Wi-Fi router.
• સિસ્ટમ અસ્થિરતા/ક્રેશ: This could be due to overheating (ensure proper cooling), a corrupted microSD card (try re-flashing the OS), or an inadequate power supply.
• સામાન્ય મુદ્દાઓ: The Raspberry Pi community forums and documentation are excellent resources for troubleshooting specific problems.
