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.

using a new charger would be the best and safest thing. get an universal one and you can use it with other laptops as well as a spare part
no new battery needed

I've never personally been a fan of universal power supplies as I don't trust unknown designers to create a supply that meets the requirements of each laptop. Power supply design is not simple [I'm a HW engineer] and why risk a problem with your laptop. Probably OK to run without a battery--I've certainly done that myself but this also depends on how the laptop internal power supply is designed. I can't understand how current could be leaking out of the [presumably] plastic case of the supply. Sounds risky to me. I would replace that supply ASAP. I would also verify the UPS is outputting the proper voltage and is properly grounded. Can't hurt to check.
If the machine meets your needs for now, consider getting a new battery. I've had mixed results ordering from Amazon, but they have good prices. I have ended up with batteries that were clearly used so be careful. One quick check is if there is a date code on the battery. If this is an externally removable battery, also check the connection terminals for wear.
why risk a problem with your laptop
For batteries, I would never get one from amazon for a laptop. Could be just old or fake or even dangerous while charging.
universal power supplies are better than you think, depending on the brand and model you are buying.
Before getting a noname PSU "designed" for the laptop you have, you should consider that these actually aren´t better at all.
Only the original Dell PSU would be safe then if you go this way. But for a 2011 laptop I wouldn´t spend that much money to get it running again.
For batteries, I would never get one from amazon for a laptop. Could be just old or fake or even dangerous while charging.
Not trying to start an argument but wanted to elaborate a bit. I respect your opinions and I'm the newbie on the forum [but recently retired after many years as an engineer].

If you need to replace a new computer, you can choose to use tape, but I still recommend that you buy a replacement power adapter, which is safer and cheaper, anyway, you have to replace the new computer, the power adapter It does not matter whether it is original or not.
