black screen and rcm mode not detected

Hello,

I cracked the switch last week with Atmosphere and everything went well, I was able to play it.
Only, last night in the middle of the game, the console turned off (black screen) there was about 10% battery left.
It stayed on the deck all night but today it was impossible to start it. I tried several manipulations (power for 15 seconds, hardware reset) and also tried to put it in RCM mode with TegraRcmGUI but it doesn't even detect it anymore. Not even sound when I plug it into the PC.

If someone can give me some of their expertise to resuscitate it I would be very grateful.
Thanks in advance.

How old is this Switch?
If it is 4~5 years old, then maybe the battery has gone bad.
Lithium batteries can suddenly loose power if they are very old.

Not being able to connect the Switch to a PC anymore might be a bad usb cable, a charge-only cable or a driver issue.
If your Switch screen is faintly glowing after turning on your Switch, then at least the Switch is waiting in RCM mode for a payload to be injected.
Windows doesn't give a sound when you plug in a Switch in RCM mode afaik.

Thank you for your reply.
It is over 6 years old and has been used very little. I have tried with several cables that work for file transfer.
The backlight does not work at all, it does not light up at all. Maybe it comes from a defective component then

press and hold the power butten for >12s. put your switch into the dock. now charge for a couple of hours and retry to enter RCM. if possible power, upload you payload and wait until you see your home screen. now continue to charge until you reach 100%.

Already tried without result. I took it to a technician and according to him it would be a short circuit.
