Laptop charger causing circuit breaker to trip
SolvedNoha819 Posted messages 109 Status Membre -
Hello,
I can't manage with my laptop. I have an MSI GS66, and a year ago my charger started tripping the 30mA circuit in the house. I bought another charger, and after two months, the same problem occurred.
I opted for a not-so-safe solution, which is to cut the ground wire of the charger. Since the chassis of the laptop is aluminum, I get small electric shocks all the time. So I ended up buying a third charger.
After a month, AGAIN the same issue!!! I finally cut the ground wire going to the charger to connect it directly to the laptop's ground. It worked for a while, but again it trips.
The only option I see is to disconnect the ground and keep getting shocked unless I forget to put an insulator between my feet and the floor (which, besides the danger, must be very bad for my health, like my heart and all that...), or spend a fortune on a 4th charger and wait for it to happen again.
I can't stand buying chargers and getting shocked anymore; of course, my laptop is no longer under warranty, otherwise it would be too easy...
Does anyone have an idea for a third, cheaper and safer option???
Thanks for reading, best regards, Noé.

Hello
Yes, there is a third option, to change the computer which has evidently become a real danger, from what I gather it's the computer that's at fault, not the rest.
Best regards
I don't see how the PC could be at fault; it doesn't control the power supply, it simply sends the power it needs. If I plug the power supply into the wall without the PC, it also trips.
I thought it might be because the power supply, although rated at 230W, was somewhat under-calibrated for the intensive use I put it through. It (and the previous ones) are constantly very hot; wouldn't finding a power supply rated for higher power solve my problem, in your opinion?
Any other opinions regarding a PC that burns out power supplies? Is it possible that my PC has a short circuit and consumes too much, ultimately burning out the power supplies or something like that?
Best regards

Clearly the PC is at fault!
Those things you call "charger" or "power supply" have, for the past year,
after being plugged in to power your PC, started tripping the circuit breakers at your place, and they still have the ability to trip the circuit breakers even when they're not powering the PC anymore.
Your PC seems to have already destroyed 3 "chargers" or "power supplies," that's all.
Please stop destroying power devices by connecting them to this PC; you have been endangering your life and the lives of others for a year.
Reading this whole discussion and maybe a few others on CCM as well, this is the only plausible conclusion that comes to me today.
Hello,
It is indeed quite possible that the computer has a problem leading to excessive energy consumption. This would explain why the power supply is very hot and eventually gives out.
What is worrying is the potential for a sufficiently high voltage current to electrify the user. Normally, this is a direct current of less than 20 V. There is therefore a danger for both people and the computer components. It is not surprising that with such leaks, the circuit breaker cuts the power.
I believe the only solution is to have the computer serviced, properly explaining what is happening. It is out of warranty, but since it is clearly not a budget computer, the expense is perfectly justified.
What is well conceived is clearly stated,
And the words to say it come easily.

Hello,
are you getting the same model of charger or a compatible generic charger?
because if it's still the same model from the same manufacturer, it might be the design of that one that is faulty. If you can find a compatible or universal charger (or you modify it with a connector from other chargers), more powerful (the voltage must stay the same)
Hello,
Thank you for your responses :)
First, I bought generic chargers, then I opted for the manufacturer. Since a PC repair is likely to be either costly or impossible, I will try another more powerful charger; if the same problem returns, I will then go for a PC repair. Even if, as Pierr10 said, it's costly, it's not a budget laptop and it's also my work tool...
I will try to remember to give updates with another type of charger if it resolves my problem.
Which I sincerely hope, because I can't imagine having to do without my work tool; one must make a living!
In the meantime, thank you for your advice, I am ordering a new charger to quickly stop these unnecessary risks...
Best regards, Noé
The more powerful, the greater the danger.
A PC that burns out power supplies is not common, but it does happen. (I've seen that in my profession).
A powered PC that outputs "juice" is completely abnormal and dangerous, for you and for the overall functioning. AND this only confirms that this PC has a major problem.
The number of domestic accidents due to defective devices causing injuries or even direct or indirect fatalities is not negligible, every year, just in France.
Just because the evidence does not suit you, as it implies a burdensome process, it will not magically resolve itself, certainly not by "increasing the power." You will simply multiply your risks of severity.
But it is not our house that will burn nor our health that is at stake; however, you cannot say that you didn't know.
Good evening,
I'm back to give some news after more than a year.
Since I'm a hothead, I bought a more powerful laptop charger (from an Asus 320W), and surprise, it has definitely solved my issue. I can't claim that MSI has poorly designed chargers nor explain the problem.
But the fact is that I no longer measure an insignificant voltage on the laptop's casing (a few millivolts), and I no longer feel any discharge when touching it! Phew!
So, it's strange, but after a year of use without any issues, I can affirm that the problem really came from the (or rather, the) MSI charger...
Wishing you all the best, and thank you to those who took the time to respond :)
