What to change in a laptop so that it starts charging?

Question

laptops

Greetings!

Not so long ago, I got a DELL brand laptop in the configuration without a battery and charger. Since I needed a laptop for work, compatible missing parts were urgently bought at a nearby store. And now to the problem: the battery is not charging, but it is correctly displayed in the BIOS. With a quick googling, it was found that this brand is quite picky about original spare parts. I would like to know what to change from this pair in order to eliminate this problem.

Z.Y. Recommendations from the first pages of Google did not help.

Answer 1

Never contact Dell. Sell ​​for parts and forget like a bad dream. Consider the loss of money and time as the cost of training.

Answer 2

The reason for the non-charging may be in the power supply. Some manufacturers of branded laptops, in order to prevent the use of non-original PSUs, inserted an identifier into their PSUs - a 3-pin Dallas chip, which sends some code to the computer via the 1wire interface. Looks like Dell is one of them. You can determine such a PSU by the fact that the power cable is three-wire, and the plug is three-pin.
In my practice, there was a case of replacing such a branded PSU (faulty). It was not difficult to select a suitable extraneous PSU in terms of current and voltage, but it was only possible to start it after I soldered the cable from the faulty one to it, and also transferred it from the faulty one to a new piece of the board with the Dallas chip.

Answer 3

Faced - as far as I remember, both communicate with the laptop, and should be original. Perhaps the Chinese have learned how to make suitable copies - but I don't know.

Answer 4

the battery is not charging, but it is correctly displayed in the bios.

One of the reasons why it does not charge is the deep discharge of the battery. It will always be displayed, but will not charge. On my old laptop, the battery is discharged to 0 from time to time. Then I remove it, open the case a little and hook it to the contacts (there are 18650) +19 volts from the power supply, for 2 minutes. Then I rearrange it into a laptop and there the charge already begins. This is called pushing the battery. In this case, the main thing is not to break the wires from the board inside the battery, otherwise the board will go into protection and the battery will be thrown away.

what does such an operation carry out by me from time to time, as I bought a replacement for my native battery, maybe this is your case.
I don't like Dell either.
