Anti-ESD Wriststraps...where to clip?

So I got apiece of this since I'll be upgrading the CPU of my notebook (hopefully before August ends) and I'm having trouble thinking (yes, I love to plan in advance lol) about where to place the alligator clip of the wrist strap. There aren't any water pipes or anything jutting out of our walls, and in our country there aren't room heaters that could do.

I'm thinking, since in order to have no ESD's happening people touch a metal part of a computer so that the levels between the computer and the person would be the same.. Would it be a good idea to clip the clip on the battery contacts of my laptop? (since that was what I touched when I handled my memory modules, and they didn't get fried by ESD)

Thanks in advance!

 

You don't need ESD straps as long as ur laptop is earthed.. for example ur laptop is on a floor carpet when you do the modifications

 

Uhh..we don't have one.. lol

I'm thinking I'll be working on a glass round table over wooden supports.. And we have floor tiles, the non-marble ones..

I kind of purchased the ESD straps since they were like $2 off eBay, and as a precautionary measure. I was first thinking of clipping it in a plugged-in industrial electric fan, but decided against it since it does have current running through it.

 

It's nice to have the extra safety, but I have never used one at all and have never had any problems.

 

I'v never used one.

If I did, I would connect it to any GND point on the motherboard.

I have cirecled some ground points on my motherboard in this pic:

 

Something tells me trying to keep a static-free environment doesn't include working on carpet

The wrist strap should be clipped on a metal part of the chassis. The idea is to alleviate the voltage difference between you and the computer.

 

Ding, ding, ding. Correct answer. +rep

 

Yes it should be cliped to the chassis
I've been doing computer repairs for just over 12 years and never ever used one. No problems at all. But that I dont work on carpet.

If your doing repairs on carpet, the potential is very here of static. Think about it. Rub your feet on the carpet and touch a door knob or another person. especially when it gets cold. Hellloooooo!!!!!??????

 

If I were less sleepy last night when I saw the post, I would have seen this. Lol.

Well, the battery contacts are parts of the chassis, and it is made of metal, so....is it a good idea?

@ Moral Hazard great pic, so the circle things at the screw points are GND points? +rep man, though I wouldn't be reaching it until I've actually opened my laptop. Thanks!

One part I'm worrying, though, is that our sofas are kind of the not-so-fluffy-but-non-cotton-sofas type, and as I've read cotton has the least potencial to store static electricity so this kinda makes me thing our sofa DOES store static..

 

I recommend against putting the clip anywhere on the motherboard. There is simply no need to risk damaging the motherboard with the clip. Surely there is some of the metal chassis exposed once you open the computer?

 

Hmm, all I could think of are the battery contacts, and the metal stopper-thingy when I open the RAM slots and all..

 

well i don't really know about this and when someone earlier had asked about this topic i remember darth bane or soemone saying that u could carry it out on carpets as u would be earthed.

 

I don't think you mean carpet in the traditional sense. There are such things as ESD floor mats and whatnot: http://www.esdmat.com/.

Really, as long as you're not wearing a sweater and rolling around in your shag carpet right before you work on your laptop, nothing is going to happen.

 

Clipping it into the chassis is pointless if the chassis itself isnt earthed. You need to have the power cord plugged in but with the power socket turned OFF. This will use the ground rail in the power cord to discharge the static.

Personally i ground myself straight to the power socket. This will ground me to the electrode earthed underneath my house.

 

Well, the thing is I'm not sure if our house is wired to have ground sockets..

So for example I have an extension cord that has a kill switch in OFF, which is plugged into a wall socket, would that make it grounded? Or not?

 

wear rubber gloves? lol
