When using a laptop for an extended period, it is essential to maintain a comfortable and healthy environment. In the case of a ThinkPad laptop with a malfunctioning keyboard, it can be challenging to use the device without an external keyboard. In addition, a laptop placed in a box for an extended period can be prone to overheating, which can potentially damage the screen. It is crucial to ensure that the laptop is properly ventilated and maintained to prevent overheating. Failing to do so can lead to serious damage to the device. In this scenario, it is recommended to use an external keyboard and keep the laptop in a well-ventilated area to avoid any potential risks to the screen or other components.
