If your laptop has been in a cold place, like in your car in the winter, wait for it to get to room temperature before you boot up so that condensation does not form inside; it could damage delicate components.
Laptops are constantly being moved around – things like setting it down on a table, transferring to your lap, putting it in a case, etc. This puts a lot more wear and tear on them vs a PC, so be sure EVERYTHING is always backed up. Don’t take chances on losing everything.
There is a lot of controversy on whether you really need to shut down a PC; after all, refrigerators and other appliances run non-stop without being turned off. But, when it comes to laptops, always shut down completely when you are not going to be using it for an extended time.
Check air vents for dust or particles and keep it clean~
While it is nice to keep your laptop in your lap, using it on a hard surface is really the best way to extend the life of your laptop, and helps to control overheating or over use of the internal fan.
Never reposition your laptop from one spot to the next, or from your lap to a table, without unplugging USB flash drives; leaving them in can bend them and ruin not only the flash drive, but the USB port on the laptop as well.
Use a strong password on your laptop; theft is more of a concern with portable devices.
