I have an Acer Aspire 5750 and its the only laptop I have for doing work. for some time the laptop wouldn't turn on without being plugged in to charge. After some time the laptop stopped working completely. I had to borrow my friends laptop to ask this. For some reason when the charging cable is twisted the battery light turns on orange and sometimes the laptop will turn on. I really need help!
