The power supply of the laptop gives out loud pops, the frequency is different, maybe once a minute, maybe once every 10 minutes. Only when the laptop is turned off?

Question

Power Supply

It clicks or rather loudly claps only if the laptop is turned off or the plug itself is pulled out from the laptop. That is, it does not give its energy to technology. When the laptop is on everything is fine. But it is worth turning it off or pulling out the plug, then literally in a minute cotton is heard. It gets a little creepy because the flaps are such that it seems that the block will shatter right now from the pressure

Answer 1

Turn it off and never turn it back on. Moreover, do not connect it to a laptop if the laptop is at least a little dear to you.
Give the PSU for repair or buy a new one if you can’t take it apart, look (make an audit) and repair it yourself. Be extremely careful if you decide to take a "universal" PSU.
