To improve battery life, reduce screen brightness, close unnecessary applications running in the background, use battery saver mode, and ensure your laptop's BIOS and drivers are up to date.
To perform a factory reset, go to Settings > Update & Security > Recovery. Then, select 'Get started' under 'Reset this PC' and choose the option to keep or remove your files.
Overheating can occur due to dust accumulation in the vents, inadequate airflow, or high-performance settings. Clean the vents, use a cooling pad, and adjust the performance settings to balance performance and temperature.
Firstly, check the power adapter and ensure the battery is charged. Perform a power drain by holding the power button for 10-15 seconds. If the issue persists, it may require professional inspection.
To upgrade the RAM, power off the laptop and remove the back cover by unscrewing the screws. Identify the RAM slots and carefully insert the new RAM module. Reassemble the laptop and power it on.
To enable the keyboard backlight, press the 'Fn' key along with the spacebar. Repeat the combination to cycle through different backlight brightness levels.
It is recommended to clean the laptop exterior and keyboard monthly, check for software updates bi-weekly, and clean the cooling system every 6 months to ensure optimal performance.
Connect the external monitor using an HDMI or USB-C cable. Once connected, press 'Windows + P' to select the display mode such as 'Duplicate', 'Extend', or 'Second screen only'.
Slowness can be due to insufficient RAM, background applications, or malware. Consider upgrading RAM, closing unnecessary apps, and running a malware scan to enhance performance.
To update the BIOS, download the latest BIOS update from the Lenovo support website. Run the update utility and follow the on-screen instructions, ensuring the laptop is plugged in during the process.
