The spirit of science and technology is to cut off the cable of the wired mouse and toss out a wireless mouse with different looks. Just do it, but I found that doing this is not a simple job. After reading more than n materials, I sorted out the doorway. Next, please see my little brother's wired to wireless work.If a worker wants to do well, he must first dry his tools!
