I have a cheap laptop running as a server, but its battery has died. I often get power loss during the summer, but I don't want to invest in an UPS. I wonder if I boot the server from CD-ROM or flash drive and load everything into RAM, what kind and how much damage will it do to my laptop at a power loss?

the server doesn't need to write/save any file, so I'm not worried about the data.

The only major damage you get from losing power is usually to the hard drive, so since you are not worried about data, and it is on a volatile medium, you can do that with no fear.
