The power supply for the dell 11 venue pro has broken. What to do?

Question

Do it yourself

The power supply is pretty interesting. Gives a choice of either 19.5V=1.2A or 5V=2A. And all this sends to the usb-mother. And then through the micro-usb wire it goes into the tablet. Switches by itself without any buttons. I didn’t do anything with it .. I just pulled it out of the socket. =( It steadily continues to give 5V, but 19.5 ... no =(. The tablet on i3 and I understand that 5V charges it for a very long time. I need advice. The tablet is under warranty, but!
1. There will be more than 2 repairs of the power supply -x weeks (outside the city) and xs how to charge the tablet
2. What is the most likely problem in your opinion and whether it can be repaired in the field (there is where to give it to repairmen. I'll just lose the guarantee right away)
3. If you take a regular power supply from
4. It's not entirely clear how he determines what exactly to apply to the usb side tracks ,

there may be a problem in the tablet, but for such a problem even I can't find the reason.

Answer 1

I’m afraid I won’t have an exact answer, but here are a few thoughts on this topic that may be useful:
This is unlikely.
I think that everything is done here in the same way as the SZU from ASUS ZenBook (for example). The only difference is that the asus has 3 pins in a round connector (one pin is used to identify friend or foe, i.e. "left" charging does not work), in your case there are as many as 4 pins, 2m is powered, yet according to 1(2) agreement on what power to apply.
So the problem may be in the tablet itself (for example, in the chip that controls charging on the side of the tablet)
And as a conclusion: I don’t think that an attempt to fix this bundle is justified in the “field” conditions.

Answer 2

Do they take only the charger or the charger + tablet into the warranty repair?
We have, say, a 120W ASUS gaming laptop charger dead. They took everything together for repairs - the charger along with the laptop. Decided to buy another charger.
If they take one charger for repair, the tablet, although for a long time, is charged with an adapter from a mobile phone - there is no guarantee for a guarantee !!!

Answer 3

The power supply for a Dell laptop just burned out in one day. What are the reasons or possible operating tips? I had to buy a new power supply vnv.in.ua/blok-pitaniya-dlya-noutbuka/blok-pitaniy...

Answer 4

Just plug in the original cord that came with Dell and you will see in the diagnostics instead of 3W in the AC Adapter 23W column.
