When buying a used laptop you must be careful online. You must realize that many times people sell used laptops because there is something wrong with them. Sometimes people sell used laptops because the battery doesn’t last for a long time anymore, and the price of the new battery is $150 or more, while the price to buy a new laptop is $499. So the person selling the used laptop figures they would be better off to buy a new one than to put more money into the old one, when they are going to need a replacement soon.
You must be skeptical as to why people are selling a used laptop and be cognizant of all little things that can go wrong with laptops; such as all the keys being worn off for instance. That can be a real problem if you are a writer or you will be using the keyboard a lot, or if you’re not used to that particular brand or keyboard it might be very difficult for you even if you are an excellent typist and your fingers automatically know where all the keys are.
But that’s not all, you must also be careful that the laptop is not stolen. A stolen laptop can be a real problem especially if the software on it is registered to someone else. And even if the person who stole the laptop erased the hard drive to cover their tracks, there are still issues with the serial number of the laptop in case you ever take it in for repair. The used repair shop will run the serial number. How would you like to get arrested just for taking your laptop in for repair? Please consider all this.
