Clevo M860TU "Grounding"

Whenever my laptop (Clevo M860TU) is connected by AC power, the palm rest just below the keyboard seems to emit some sort of grounding to my hands. It seems to be the bezel surrounding the keyboard and trackpad, I believe it is aluminum, if I'm not mistaken. When it is on battery mode, the sensation of the grounding is not there. Do you guys have any thoughts or similar experience about this? Is it a cause for concern?

 

check grounding cord in your plug, it looks there is no contact between groung pin and so-called "earth"

 

Unfortunately, in my country, we do not use the "ground" on our plug. With regards to other laptops, I have never felt that grounding sensation. Is it something to be worried about?

 

My M1530 does the same thing, if I touch the metal below the keyboard a particular way, I can feel a gentle buzzing sensation. It is not a 'shock'; just the sensation that there is perhaps some static being discharged.

It is just the way it is, there is nothing you can do. Ive lived with it for a year, I never even notice it tbh. We do use grounded sockets over here, but for whatever reason they shipped me an ungrounded PSU. I could have requested a grounded PSU and it would have gone away, but never bothered.

 

use a surge protector or UPS that has a LED indicator for the "Ground"

 

So it's definitely due to grounding that's causing this? Yah, it's really not a shock, just a little sensation of having static flowing through your fingers, tbh at first I though it was due to the finish of the laptop then I noticed that it runs away when I'm running on battery.

 

Gophn is this suitable for my m860tu in my country ? I have experienced the same thing as kevin decribed

I dont think that would work for high-end notebooks... since they draw more power than that particular adapter can give... as well as the two prong might not fit.

I think something like this would due:

it has a LED indicator for power and ground... so its good for monitor that kind of stuff

 

Just a suggestion: open (if you can) your PSU & check if cable, which goes to groung prong is OK. If not, just fix it.

On my previous laptop I faced the same problem and was really pissed off with this. I fixed it and after this is was fine for me.

 

As I've said, we don't use "ground" in our country, so I purposely broke the ground (third) prong of the wire so as to easily plug it in our normal sockets.

I've used two PSU with this laptop, both brand new and they produced the same effect. What I'm concerned at is why is this issue not present on most laptops I use? Considering that I also don't implement grounding in those laptops.

 

just change the cable that's going from brick to socket with "normal" one. that's what i did.

 

Where're u living?

If you had broken the 3rd prong, it's no wonder why it's not working

 

@votdfak

What do you mean by "normal" ?

@starche_old

I'm from the Philippines and as I've mentioned I "intentionally" broke the 3rd prong since it's useless as our sockets don't do grounding at all, they only have two holes.

Again, I'm wondering why is this issue not present with my other laptops?

 

I had this issue with my _dell when it was not being properly grounded. Is there no way to get a grounded socket at all in your country?

 

Are your other laptops made of metal? The reason this happens if owing to the metal on the laptop.

Surprised that you have no ground at all! How do kettles and laundry machines work?

Neil.

 

Ahh. Forgot to consider that, my other laptops surface are plastic I think. And this Clevo M860TU is supposed to be metal all over the bezel of the keyboard?

Well, ever since grounding is not implemented in our country. For kettles and laundry machines, just simply plug without ground, that's it.

really, how does ovens, washing machines, etc. works w/o grounding??? Sorry, I do not believe they are.

I lived for 3 years in Malaysia and there is UK-type of sockets. What kind do you got?

 

they just do work. i have the sockets that have only two plugs on them, either 2 round plugs or 2 straight plugs.

 

WOW... By Canadian Code all equipment over 1kW (if I'm not mistaken) must have grounding prong...

 

Hi all,

http://treehouse.ofb.net/go/en/voltage/Philippines this is what the plugs look like in Phillipines, same as some european plugs(the bottom one)

new electrical installations have provisions for grounding under the Philippine Electrical Code.

The way it works is different to U.S. it has a sensitivity circuit built in and drops the main breaker in case of short circuit caused by appliance, hands on wire or touching wires between each other, this functionality is in the circuit breaker.

What type of surface is your floor?

 

jings - wouldn't like to be risking that everyday!

 

Well, since the OP is experiencing current leakage, this system isn't working to well IMO.

Since there is no way to ground the laptop, you should take Gophn's advice and use a high rated surge protector, since the only way to stop current leakage in your case would be to supress the surge through the live wire. Good luck kevin.
