Static electricity

[kemanpana]

Do you guys who technician or just usually take a look into your laptop hardware to just regular thermal paste change or fan cleaning used ESD gloves or ESD wrist during work with laptop? I want to take care of my laptop with my own hand but dunno why I'm still scared of static electricity cause i saw one video about that can cause damage to component. My current house isn't grounded is there any precautions that i need to follow?

Proper english and formatting is a virtue.

There are numerous things you can do to avoid ESD damage, but the main thing is that once you sit down to do the work, ground yourself by touching something earth grounded to dissipate the static charge you might have.

Don't do anything silly like rubbing a balloon against your head, or if you get up or do other static-building movements, again touch some earth grounded point to discharge that.

Easier answer is just use an earth grounded work mat, or an ESD wrist band, or just strap/stick/poke/fondle yourself with a 1 meg resistor and wire that to earth.

What does "my current house isn't grounded" mean exactly? If your wall mains AC outlets do not have a working ground connection, do not use any equipment that needs an earth ground as evidenced by having a 3 pin outlet plug. That is far more dangerous than frying something with ESD.

If you don't have grounded outlets then I would seek a ground for a wrist strap or mat with a wire connected to (hopefully) metal plumbing pipes, and talk to an electrician about wiring the premises appropriate for what you're powering.

Laptops typically have only live and neutral, not earth ground so they due to their insulated ABS PSU housings and isolated output, don't need earth ground, but many other things like a desktop PC or many types of metal enclosed appliances usually will need earth ground to operate safely.

A bit more info might be needed. What concessions are you already making due to, the best I can interpret what you wrote, not having an earth ground?

Best answer is get an electrician on site to survey and make the needed corrections.

However, recognize what ESD is. It is a path between the static charge that your body built up, and ground. You can handle all sorts of things while being at a higher potential than earth ground, as long as the thing you're handling does not have a path to ground itself, so there is nowhere for the static charge to go, except that something else could have an opposite charge, which you can still dissipate by touching that "something" before handling the sensitive component.

So if what you are working on does not have an earth ground, disconnect it and yourself from everything else that might. A specific situation after a site survey would allow a more definitive answer.
