Last week, adapter on my computer broke down and delayed many things. Because usually do not use the computer so stay at home and do not go to regular computer cleaning and inspection, I do not think there will be any problem. But there was an emergency last week to send an email from my home computer. When I opened my computer, the computer had been out of use for too long, waiting for me to plug in the power, and then take it to the room, and the master said my adapter was bad for a new one. Because I didn’t use it for a long time, I didn’t do the check, I didn’t know when adapter was bad, and it didn’t take long to repair it. After that, I hurried home to deal with the mail. In the future, we should check the computers regularly, otherwise we will not be able to delay things.
