hello,
I accidentally broke the "lever arm" of socket 370 on motherboard.

[reason was cpu got glued to heatsink, which I didn't know at that time, and when I was trying to plug in cpu + heatsink I broke off lever arm :( ]

now I can't lock the "lever arm". and when I'm trying to turn on pc I get none stop beeping sounds.

I get that beeping sounds when everything but power is unplugged, and I get the same beeping sound with all possible combinations of plugged in hardware.

after hours of trying to fix it I just don't know what else to try :confused:

to be more specific I came down to two questions,
Q1.
Does the lever arm pulled down trigger some mechanism that tells motherboard that cpu is in place? and with arm up it just ignores cpu?
Q2.
what will happen to pc if cpu is damaged? I mean how do I recognize this?

looking at the manual the beeping sounds are either of these two

Most likely all pins are not making connection.

Putting the lever down on ZIF sockets just shifts the top section over to catch all pins and ensure adequate contact pressure/area for maximum connectivity. If this cannot be done then contact integrity to all CPU pins cannot be assured.

Your setup is a PIII or equivalent Celeron. Machines of this vintage are good for controlling NC machines and other low grade manufacturing and control tasks, especially DOS based tasks, but as general purpose machines, they aren't worth much in cash, even if they're working.

Your ZIF (Zero Insertion Force) socket is broken, and replacing it successfully isn't likely, even if you have the required soldering skills. If you really need this kind of machine for some purpose, your best bet is to try to replace the motherboard with the exact same model. That would allow you to use your RAM, hard drive, etc. without having to re-install Windows.

Any other board would require re-installation or a massive recovery effort that would cost more in time than the machine is worth. The other possiblity would be to find a similar used machine.

If you need a working, general purpose machine, it will cost less to build a new one and transfer your files, especially when you consider the value of your time and the performance you'll get for the time and money you spend.

Good luck. :)

Heh, I did the same thing with a Socket A system. In fact I've been using it sparingly as an HTPC, and I pretty much did the same thing as you. I used a screw driver to somewhat turn down what was left of the lever arm, and I also pushed the processor itself downward. Then I clamped on the heatsink and prayed it worked. Thankfully it does, although every so often Windows will reboot and say it recovered from an error.
