I have an older Compaq 2596 notebook that I want to refurb. I won't get into too much detail, but the CPU is toast --- won't boot. Some web searching (and finding some really old forum threads) shows it should be a P4 2.6Ghz. It looks like I can find some out there at various cheap prices. If I get one, it it just a matter of inserting the chip? Or is there something that needs to be done in BIOS? Unless there are other problems, will this likely get it to boot up again so I can do other things, like reinstall/upgrade the OS?
