Almost Fetal Damage

I am in trouble suddenly. My Laptop PC shut down when I was typing. Why? When a battery gets worn out, some power supply troubles sometimes happen unexpectedly. After struggling with turning it on again in hours, finally it came back. I was paled because I thought that I lost important data.

For business people, performances turn out to be 50% without PC. Losing data may have the impact of a fetal damage. It is very important for us to maintain own PCs because we can't live without PCs!
