Laptop (笔记本) computers make people's lives even (easy) as people can take laptops anywhere. They can work, shop, or play games any place any time. there is a problem with laptops. People can (burn) by them!
People who sit with laptops on (they) legs for hours and hours have noticed they get dark marks on their legs. The hot laptop is toasting the skin. (doctor) have noticed more people show up with "toasted skin syndrome (综合症)". The marks are not (danger), but they look strange because they are just in one spot on people's legs.
Companies that make computers tell people not (let) warm computers touch bare skin for a long time. Wearing pants and putting a laptop's case under the laptop is (usual) enough to protect one's skin from the computer's heat.
