I have a Dell Latitude L400 that I want to play around with. I've replaced a few of the itmes on there but ran across the CPU. A few questions:

What kind of CPU does the L400 use? All I know is that the CPU it takes is a Pentium 3 Mobile at 100MHz FSB & 700MHz clock. I see a 800MHz one on eBay for $10 shipped that I would like to get.
The CPU seems to be stuck on the motherboard socket. I see no release lever to take it out. Do I just need to pull at it harder?
Does anyone know how to reduce the EMI that gets absorbed by the earphone plug? I get a lot of static in them as the hard drive spins.

Does it realy have a socket? If yes there has to be a release mechanism. If no the CPU is directly soldered and you won't be able to remove it without damaging it and the board.

ah, i guess we have a problem then. I've looked around and around the white plastic socket area but did not see any release mechanism whatsoever. I guess that's why I see some CPU's on eBay with the socket still attached... is there a way to remove that whole thing safely? probably not.

The speed difference between a 700 and 800 Mhz Pentium III mobiles is not big, certainly not big enough to undertake the risk of destroying both the motherboard and the CPU - or, effectively, to destroy the laptop, as after that little operation the only thing it could serve as would be a doorstop or something similar...

yeah, that's fair enough. I just have a lot of fun modding things that weren't meant to be modded. So far, I've had the entire heat sink of the laptop re-molded in copper as well as the drive caddy. The 7200 rpm drive i put on here is burning up the entire laptop in very literal ways. Gotta keep it cool somehow.

I once read in a magazine about a 486 which was clocked to 1 Ghz and cooled with liquid nitrogen... Don't know how that's possible, but it was a great story anway :)

whit the older notebook there is no lever or anything. it could be the case that if you take a closer look at the socket next to the cpu there can be a litle gap between processor and socket on both side's. on one side there wil be space between cpu und the edge of the socket.
now you have to take a small screwdriver put it in the gap with no space between the cpu and socket and gently push she cpu to the other side. when the cpu is on the other side it should come lose. installing is in the reversed order of course.

hope this is the answer to your question
