Sony Vaio Notebook automatically turns off after 12 hours. Is that normal?

I bought a Sony Vaio (VGN-NS 31 M) from a private person a few days ago. This informed me that the radiator was cleaned, the battery was new and thermal grease was applied. The notebook (Intel Core Duo 24.4 Ghz, 64 bit, 4 GB RAM) would supposedly run flawlessly.

I use the notebook to run a computer program for several weeks. By the way, I leave the charging cable to it, because the battery is empty after a few hours and the notebook then turns off completely.

I know that notebooks have the safe setting when the temperature of the CPU becomes too high, the notebook then automatically shuts off.

The notebook will turn off automatically after just over 12 hours. However, according to the statement of the seller, the notebook is in perfect condition.

So my question: Is it normal that in my case, the notebook switches off completely after 12 hours?

Check the energy settings.

Maybe there's something activated.

Otherwise, check the event viewer.

For your project, I would rather get something server-like.

Is not really normal, maybe the person has a program on the notebook had the notebook automatically turns off

The notebook runs in power save mode, but that can't be the reason, right?

I do not know, but I call the seller again because of it.

This has nothing to do with overheating. Finally, the fans would run on high turf before.

In addition to settings, something can also be located on a cold solder joint, connecting contact.

Look in the Event Viewer. You are sure that it is S5 and not S3 or S4?
