Having been involved in ancient laptops in our computer museum, let me just state the Law of Diminishing Returns here:
If it costs you less to buy a replacement from eBay than to fix it...
A quick Google scan shows Dell 133 PPS laptops going for about USD$40. What's your time worth to fix this machine? Can you get the data you want off it by some nefarious means without too much effort? Are you NOT REALLY that personally attached to the unit?
If yes to these questions, do that, buy a new(er) one, and then give the busted one to some laptop shop as strip-down spare parts or something. If you are REALLY stingy, strip out anything useful before you give it away.
And remember, once it's busted and superseded, you will NEVER turn it on again so don't bother hoarding it "just in case". Dispose of thoughtfully.
