Old laptop stuck?

Hall oils. I found an old laptop (Thinkpad 600e) in our attic. I wanted to examine it for relevant data before we throw it out. When tackling, however, the entire surface was glued. Now I thought something sticky must have leaked over it or something and start rubbing it with a cloth and it will be coal-black. Also on my hand, especially on the thumb where I recently injured my skin, the stuff settled everywhere and didn't come off underwater for a good while. Now the thing is here and I would have to operate it with rubber gloves…

Does anyone know what that is, whether the health hazard is and how to get rid of it if necessary?

These are remnants of the original plastic coating. I know the effect from a very old joystick. You shouldn't eat it. But you probably won't die soon either.

Get away?

The e-waste container is good for that.

It was probably very hot in the attic in summer and the plastic has dissolved / melted due to the heat.

I found that:

"LCD cover: IBM UltraCarbon (tm). This is a carbon fiber reinforced plastic. The cover is rubberized" (https://thinkwiki.de/600E)

You have a rubber that is changing its physical state on your fingers. Uncomfortable, but not that bad.

"Rubber is very durable and can't be dissolved even after many decades and despite embrittlement. If the rubber comes into contact with substances that it can't tolerate, it becomes https://www.hausjournal.net/gummi-wird-klebrig, liquefies or he https://www.hausjournal.net/gummi-loest-sich-auf. However, rubber always remains in the substance and only changes its physical state. " (https://www.hausjournal.net/gummi-aufloesen)

So rub it off, e.g. With hand washing paste, would have to remove the last residue from your fingers at some point.

And cover the lid with a suitable paper, maybe just stick to the rubber when you press it on.

Complement:

If the material should be TPE, as specified by Seefuchs, the following procedure is recommended:

(https://www.srf.ch/audio/trick-77/wenn-plastik-klebrig-wird?id=11622211)

"The simplest trick is to cover the sticky area with a (decorative) adhesive tape. Another possibility is to bind the sticky covering. To do this, rub it with corn starch or baby powder and wipe the surface dry. It helps to clean it with normal cleaning agents Don't go any further, listeners need sharp guns: nail polish remover, alcohol, synthetic resin thinner, mineral spirits, orange oil cleaner. Tip: Of all these agents, orange oil cleaner smells the most pleasant. This is applied with a cloth and the concentrate is allowed to take effect for about an hour. Then the sticky layer Rub with a cloth. Repeat the process if heavily soiled. If necessary, use a small spatula from the nail care set. Attention: Wear gloves and ventilate the room well. Experts mention that cleaning can remove the sticky layer, the plastic, due to the lack of plasticizers, but no longer have the same properties as before. "

That was a soft-touch surface. In this case, the plasticizer has separated over time and is therefore concentrated on the surface and ensures that the plastic no longer has any cohesion.

You can't solve the problem unless you remove them all. It shouldn't be harmful, but I wouldn't eat it.

If you only want to use it for a short time, just stick Zewa on it and then put it in the electronic waste.

That is not a rubber (elastomer) that is much more like a TPE or plastic + plasticizer Everyone is allowed to call rubberized but it is not rubber.

Thanks for the hint!

Up to what point in time (year) can you assume rubber if "rubberized" is specified? So when are TPEs common?
