Hal Finney managed to mine a hundred thousand coins in a span of three months using his laptop as was stated on his blogs and whatnot. That would give you a thousand coins mined per day using only your weak laptop. In today's rate, that amount of power would never amount you to anything and you'll most likely burn your laptop in the process. You can still mine though, and looking back with full of regrets won't help you get any money. Get some decent GPUs, mine some coins, then trade to bitcoin.
My first bits (pre asic age) was mined using a second hand
something like AMD probook with 2 gpu on it ... that machinery computer is fully disassembled now, I only kept the HD for proper disposal ...
I have no idea where the mind Satoshi are nowdays ...probably it went to a blackhole
