In fact any maker should void the warranty for that alone. It's NOT safe, you took the risk and now want to know why it worked? Count your blessings it did and didn't just burn out.
2. YOUR CHOICE. A good machine can handle it either way.
1. What does removing the battery and putting it back in do on a laptop that powered on but had a black screen before I did that. After I removed the battery and put it back in, it booted right up. Just would like to know why?
2. Should you leave the Power Cord connected to a laptop after it has been shut down?
I would appreciate it if anyone could answer these questions for me. Thanks,
