PC crashes when plugged into the power outlet

Hello txiki

We have to get used to expressions on the forum that may sometimes be Canadian, like PSU for power supplies (comes from their proximity to the USA, as the English word dominates even in Quebec), "char" for car, "savoir" for to be able to, or simply "modern", anglicisms or words twisted from their original meaning, we often have "languages" of gamers or "jeeks" from social networks. Sometimes we need to restore a bit the meaning of our technical terms to be understood.

Here it's probably the power cable with its charger for the laptop, this comes from shopping sites: one often has to look for the charger in the cable section, including on search engines, and more recently emphasized on the American continent it seems.

The context with the changed battery and plugged into the mains helps but not completely.

But it’s probably overheating or crashes or both—so the battery and charger were replaced for nothing.

Here, it’s ccm that’s to blame when they set up the "me too" button, the user just read a discussion describing the problem but we cannot know precisely what they read. Moderators might know a bit more but not us simple members. It's a dialogue of the deaf, we have to guess and beg for clarifications.

We find ourselves discussing among ourselves before being able to attempt an answer.

On a laptop, there are different power settings available in Windows whether the laptop is plugged in or on battery. The user must make and test several settings according to the expected result in the power section of Windows on their laptop, and depending on the program used, everyone may have to make different choices.

Some laptops are capable of "on the fly" using either the CPU’s graphics card or the independent one; again, depending on the game, the laptop may sometimes prefer to let the laptop choose or impose the independent graphics card, there’s no one-size-fits-all rule for all programs and games.

Some settings or optimization programs are too optimistic for one PC and not for another, sometimes installed by a gaming platform or the game program or a manufacturer like AMD, Intel, or Nvidia, we're not always aware of them. Some programs are so powerful that it’s up to the user to set the max temperature limit of the component, trying out settings like in overclocking.

When plugged in with power being released, some laptops start to heat up, causing either a drop in performance due to automatic frequency regulation, very loud or insufficient cooling due to excessive temperature, or instability and crashes. The solution varies depending on the PC, the game, the optimization program, and especially the ambient temperature. Options need to be tested here and there.

Very often, we don’t even know all the optimizations present, and the user doesn’t always know either, or doesn’t mention it.
