I have a function on my computer called "Lenovo Rescue System" it is used to bring your computer back to Factory settings. A friend say, if you use it too much, you can damage your computer. I say. If you follow all instructions to the letter,especially the one that tells you not to shut off your computer until the process is completely finished your computer will be fine I also think. If using "Lenove Rescue System" to bring your computer back to factory settings too often would harm your computer, there would be some kind of warning. Who's right?
