I want to help someone upgrade an oldish laptop from 11.10 to 12.04, which requires PAE. I am not sure whether they have PAE or not.

I know it is likely that they do have it after all, but how can I tell before trying to upgrade?

To check if your processor supports PAE, try
grep --color=always -i PAE /proc/cpuinfo

If it outputs something, you have PAE support. Otherwise, the output will be empty.
