Explanation
One of the possible causes of a laptop randomly turning off is liquid damage, which can cause short circuits, corrosion, and overheating of the internal components. Liquid damage can be hard to detect, especially if the laptop has been dried or cleaned after the spill. However, one of the indicators of liquid damage is the presence of small sticker paper within the device that changes color from red to blue. These stickers are called liquid contact indicators (LCIs), and they are designed to show if a device has been exposed to water or other liquids. LCIs are usually red when dry, but they turn blue or purple when wet. LCIs are often placed near the ports, battery, keyboard, and motherboard of laptops and other electronic devices. LCIs can help technicians diagnose liquid damage and determine if the device is covered by warranty or not.
