Galaxy S7 seems dead. Volume down + power and other combinasons not working. Dong when plugged to PC

[AC Question]

Hello everyone.
My Galaxy S7 is not booting. Black screen. No Lights. Had about 90% battery when it failed.
I have tried forced boot and recovery boot whith the volumes, home and power keys; All combinasons I could find on the net. For more than 1 minutes for each try. No signs of life.
I plugged it to my computer via USB and windows found a device Exynos 8890 but could not install any driver. Windows did make the USB plugging sound. Windows also makes a sound when I press the phone power off and on. With slighly different tones.
I have downloaded Samsung latest USB drivers to see if I could go further, but than does not change anything.
Any help from anybody ?
Thanks !
Ben

Plug the charger into the phone. Let it charge at east overnight. See if it comes on then. (If the battery threw a dendrite at 90%, it would now be at 0%, and it's going to take time to burn the dendrite off and recharge the battery. If it shows any sign of life after that, have the battery replaced. [Unfortunately, even though dendrites are factory defects, they're not covered by the warranty.])
