Im confused about socket 478 mobile

Jun 11, 2018 12:32AM PDT

So i have an old pentium 4 m laptop (thinkpad a31) with the Intel 845MP chipset. I tried to search ebay for socket 478 mobile cpus but i came across core 2 duos, which shouldnt fit in that laptop. But they were adverticed socket 478, not 479. So im really confused right now. For clarification, im talking about mobile sockets. I can't seem to understand that.

So i found out that those c2d's were just mislabelled mpga479 chips. So i looked out only for actual 478 chips, and bought the most powerful one. And yes, my "laptops" coooling system has been modded. Actually its not a laptop anymore. When i got it, its screen was smashed with a hammer and the keyboard was bust. So i just put it in a shoe box and cutout holes for io and disk drives and stuff. So the i had a kind of desktop.

Not confused here.

Long ago I helped a consultant with 478 based laptops. What a disaster in motion. We found we couldn't use the fastest 478 since there was no way to dissipate the heat. If you put in the fastest 478 you could find, there would be melting plastic and scorched legs.

Now there were mobile 478 CPUs but at this far out from when they came out you would be hitting the lottery to find any today. Is that the problem? If you have a working P4m laptop, leave it be. There is no upgrade path short of maybe putting in a SSD which I did on a 2006 Dell Inspiron e1505 with a dual core Centrino. It had 1GB RAM, ran W10 and would boot from cold in 35 seconds to a web page open and loaded.
