Some of our users reported about slight current shock or sensation of current on their laptops when they are using them while they are plugged to the power port for charging, this happens not only with a single brand laptop as it happens across a wide range of laptops including premium brands like apple, sony and dell etc.
First if this is happening with your laptop or desktop, then firstly its not good for the machine as its getting more current than required so this way it could affect the life of the computer you are using in the longer run, however there are very simple and repairable solutions to this problem.
Make Sure The Power Port is Earthed Properly
One major reason behind the current sensation or current shock from your laptop while using it and its getting charged is because when the power port not earthed properly to which the laptop is connected while charging. In order to check whether its due the wall socket, you can follow the procedure below, you will need a current tester which is a screw with a led inside.
- Take a standard screw driver (tester) and insert it in the RIGHT hole of the socket (Keep the switch ON). The light on the tester should glow. This is normal.
- Take a standard screw driver (tester) and insert it in the LEFT hole of the socket (Keep the switch ON). If the light on the tester glows even slightly, This is NOT normal.
- Take a standard screw driver (tester) and insert it in the UPPER BIG hole of the socket (Keep the switch ON). If the light on the tester glows even slightly, This is NOT normal.
You have EARTHING problem if 2 and 3 are TRUE above, and you need to replace the switch and call an electrician to fix this and make sure the earthing is right after then.
Current Issue with the Charger or Laptop
Another possible reason behind this problem could be due to the faulty charger, if your laptop is old enough there are chances that it could be happening due to the faulty or damaged charger or some times it could because of damaged battery or short circuit problem with the laptop as well, so make sure to get the laptop checked as well if changing the power port does not solve the issue and you still get the current shocks.
