@Chino de Oro​ 

For the first deviceT5820, the error number is 1-3, but for the second device T3610, I did not find anything.

1, 3 is a bad code (hardware issue).  Memory, CPU, or motherboard.

For the 3610, go over the steps for no boot troubleshooting  https://www.dell.com/support/kbdoc/en-us/000124359/dell-computer-does-not-boot-to-windows-10

I tried all the pieces individually and they work but when I connect them it come a blinking any solution plz

There is something amiss in your troubleshooting test.  If they are all in good working condition, there should not be any issue.

It seems to me that you have no solution to my problem. 

Correct, while we/I can provide advises and/or suggestions, only you can actually do the work.  I could provide the documentation, answer to your thread question and tell you what happened to your machines through the error blinks codes.  But, I can not fix it for you.

Hello,

there's something that's troubling me reading this, sort of. Have those 2 units failed at the SAME time ? If yes, is your power distribution ok ? Are lights in the building ok ? Fluctuations ?

Are you using an ups ?

@mazzinia_​ 

Yes, I use UPS, but I disconnected it.

After I cleaned it and heated it with a hair dryer, it worked, but when I restarted it returned to the same condition.

May I ask which brand and model of ups ? 

Just as a reference , an ups in the class of an APC SUA-1500 will NOT damage the psu of workstations or cause damages in general. An Ups more consumer grade will cause damages ( normal gaming pc will not have issues instead ).

There's a complex technical topic about this and is related to the Sin wave of the current, and the way is approximated by an UPS , a bad approximation causes stress over time in the components (psu) of workstation/server class hardware. 

This said, heating up is a trick that works with capacitors having issues > likely motherboard issue (unless you heated up the psu too, in that case just do a psu self test in both to have also that checked )

@mazzinia_​ 

how to perform a power supply self test!?

@LocalNeox there's a small black button on the back of the psu

Try replacing the size 2032 battery with a new one on both of them and see if behavior or error code changes.

@bradthetechnut​ 

same problem :(

Did you try the PSU test @mazzinia_ gave?  What part did you heat up with a blow dryer to get it working again (though temporarily)?  I never heard of that before.

I take it you already tried bypassing the UPS and plugged directly into an outlet.

As mazzinia touched on, UPS needs to have true sine wave, not an approximation, quasi sine wave, etc.

Some event must've happened that knocked them both out.  As we can't decipher from here if it's for sure the PSU's or MB's, your best bet might be a computer shop.  If it has anything to do with the UPS, I'm betting it's the PSU's.  Blinking amber can mean bad PSU and solid amber bad MB or MB component.
