Lenovo LAPTOPS user manual

The boot menu for Lenovo laptops can vary depending on the model and the operating system installed. However, most Lenovo laptops usually have the following key combinations to access the boot menu:
1. Restart your Lenovo laptop.
. During the startup process, press the appropriate key combination for your model repeatedly. The most common keys used to access the boot menu are F1, F2, F12, or Delete.
3. Once in the boot menu, you can use the arrow keys to navigate and select the desired boot option (such as booting from USB or CD/DVD drive).
4. Finally, press Enter to confirm the selection and proceed with the chosen boot device.
It is important to note that the key combination may vary, and you may need to consult your laptop's user manual or Lenovo's support website for specific instructions related to your model.

If your Lenovo laptop screen goes black, there are several steps you can take to troubleshoot and potentially resolve the issue:
1. Check the power source: Ensure that your laptop is properly connected to a power source and that the battery is not completely drained. Try plugging in the power adapter and charging the laptop for a while before turning it back on.
2. Adjust brightness settings: Press the function key (Fn) along with the corresponding function key that has a monitor symbol to increase the brightness. Sometimes, the screen may appear black due to low brightness settings.
3. Disconnect external devices: If you have any external devices (such as monitors or projectors) connected to your laptop, disconnect them and restart your laptop. Sometimes, compatibility issues can cause a black screen.
4. Force restart: Press and hold the power button for about 10 seconds until the laptop turns off. Then, release the button and press it again to turn it back on. This can often help in resolving software-related issues that may cause a black screen.
5. Check for display settings: Sometimes, the display output may be set to an external source or a different display mode. To check this, use the function key (Fn) in combination with the display toggle key (usually F7, F8, or F9) to switch between display modes.
6. Connect to an external monitor: If your laptop has an HDMI or VGA port, you can try connecting it to an external monitor or TV to check if the problem lies with the laptop's display or its internal components.
7. Update graphics drivers: Outdated or incompatible graphics drivers can cause display issues. Visit Lenovo's official website or use the device manager to update your graphics drivers.
8. Perform a system restore: If the black screen issue started after a recent software update or installation, you can try performing a system restore to revert your laptop back to a previous system state when it was working fine.
If none of these steps resolve the issue, it might be a hardware problem, such as a faulty display or graphics card. In such cases, it may be best to consult a professional technician or contact Lenovo support for further assistance.
