Seized up processor ZIF socket

[Web Gecko]

Howdy

I am upgrading an old 486 DX2 66 system (to 486 DX4 100 and
maybe 32/64 MB RAM) for a friend. These systems are still viable
with Win 95 if you don't need power or DirectX/AGP video.

The problem I have is that the socket 3 ZIF socket is siezed up
i.e. you raise the lever to 90% as far as it will go and the ZIF plate hardly slides at all. So the processor is still tightly locked into the socket with the lever all the way up.

I don't want to damage the processor or the socket (any more than it may already be).

Anyone got any ideas ? They are all welcome.

Thanks

You may want to try a little wd 40 spray.
Work it in by lifting and lowering the lever.
See if it will come up any further.
Once it's up,and the cpu still won't budge,try getting a small blade under the corner of the cpu and one corner at a time,attempt to pry it up.
Once out, spray the socket again and work the arm.
After this procedure,spray the socket down with some isapropyl alcohol(91%)
Turn the motherboard upside down and allow to dry thoroughly(very important!!!)

Thanks Alfie,

I'll give it a go.

Hey Alfie ,

Before I go ahead with your suggestions, if I spray the WD40 along the edges of the processor, enough will get into all the ZIF holes ? Also, how long do I need to wait for the ZIF to dry out after application of the isopropyl alcohol ?
I can put a fan on it to speed it up. I'd hate to power up and blow this baby.

Also is WD40 flammable or corrosive ?

Thanks

Spray lubricants are of a petroleum base,so naturally if exposed to an open flame...
Such sprays are not corrosive and in fact can revive certain plastics,metals and other materials.
The concept here,is to get some in the socket,it's a penetrating spray so some will get in.Hold the mobo sideways and spray around the edges of the cpu.
Make sure power is off to the motherboard,and have the motherboard out of the case!
The reason you want to use alcohol afterwards is to remove the oily residue left by the spray.
As you know alcohol evaporates quickly,if you can have the mobo upside down with a fan blowing on it, overnight would be most prudent,but 2-3 hours would suffice.
The surface may appear dry,but you want to make sure the little holes are completely dried out.
WD40 and other sprays like it are excellent cleaners for computer cases and parts,once again alcohol is best applied afterwards to remove the residual slickness.
