How much swap on laptop?

[ArcosCom Linux User]

I have a Dell laptop too, with sata drives.

I use it with vmware player to run virtual machines, many servers (http,
mysql, etc... for tests) and I had problems when hibernate machine because
my swaps were being used.

I think, for normal user (web, openoffice, and so on), you need, at least
for hibernate, 1xRAM swap space, if along the time you'll need more, you
can add to your swap space "swapfiles" with no problem (at least I have 1
partition for swap plus 1 swapfile).

All depends on the type of aplication you will use on your laptop.
