After school, a good friend of mine cut his notebook in half and threw it into a lake. I don't think it's okay because it harms the environment and there are extra containers for it
My question is: If one day a person finds his laptop on the bottom of the lake, then he can theoretically restore the data on it, regardless of whether he previously deleted it normally or not?
It depends on how bad the hard drive has been damaged.
And whether it is a HDD or SSD.
Depends on how long and whether the data is on an ssd or hdd.
with an ssd, with luck and little damage / corrosion, you could simply connect it and it would work.
with a hdd only a professional data recovery company could regulate what. HDDs are in a protected housing into which no air can penetrate and so it should only look worse with water.
I think that was an old part of netbook with Windows XP

HDDs are not hermetically sealed, but have a pressure equalization opening with a filter. But sooner or later water will penetrate through this.
Correct forgot
Forget it the thing is junk but you can of course like to go diving xD or report it to the regulatory office.
Classic hard drives (HDDs) will corrode within months to a few years to such an extent that they can no longer be read, even with the help of professional data rescuers. This will not be possible for laypeople anyway, because the rotation mechanism jams and the electronics corrode.
The flash memory of SSDs loses its charge over time and has to be refreshed (therefore SSDs are not suitable as long-term archive media), the charge should last 2-3 years. So that's in addition to corrosion.
Bottom line: if archaeologists dig up the laptop in a few hundred years, they will no longer extract any data from it. You will suspect that the lake was a religious place of worship where primitive electronic devices were sacrificed to the gods.
