To force a shutdown or reboot of the X press and hold both the power button and volume up for 10s, or even 120s:

https://support.sonymobile.com/global-en/xperiax/faq/the-device-doesnt-seem-to-charge/

"To force the device to restart or shut down:

Press and hold down the power key and the volume up key at the same time for 10 seconds.

Your device vibrates once. Depending on whether you wish to force the device to restart or shut down, proceed as follows.

If you wish to force restart the device: Release the keys at this point. The device restarts.

If you wish to force shut down the device: Continue pressing the keys. After a few more seconds, the device vibrates three times and turns off.

If a forced restart procedure doesn't succeed, you should try the 2-minute restart procedure.

To force a 2-minute restart:

Press and hold down both the volume up key and the power key for 120 seconds, ignoring any vibrations.

Release the keys. The device turns off automatically.

Charge the device until a charging icon appears on the screen.

Turn on your Xperia™ device."

I can remember that I had such a situation with my tablet in the past. It seemed to be switched off and didn't react to anything. But it wasn't off. So the solution was to hold the power swich for around 20 seconds than release it, wait for a short while (until the device is really off) and than press it again for 2 seconds. Maybe it helps on your Xperia as well....

Last possible explanation : Dead battery, which got discharged way too much.

If the battery is dying, the charge state isn't reported correctly (i.e.: with a clean battery, when you have consumed 1500mAh, you'd still have 36% left, but actually as the battery is dying there's not much left to go. tl;dr: 34% == battery actually empty).

Once the voltage drops beyond a certain point, the chip inside the battery refuses to give power to the phone (to avoid making irreversible damage to the battery due to a too deep discharge cycle). Also, once the voltage drops beyond a certain point, the charging circuit inside the phone isn't able to charge the battery (either as a protection to avoid damaging it in case it's too much defective, or because the above chip inside battery protection prevents the charger inside the phone from detecting that it could in fact charge it).

If that's the case, the normal procedure would be to remove the battery and connect it to a specialized lithium charger. But as the Xperia X is glued-shut phone, that might not be possible without a trip to a phone repair shop.

Last hope if indeed it's a discharged battery : leave it overnight connected to a charger. Even if the chipset doesn't come up (with the "charging" animation, and negociating some form of fast charging), its possible that the phone still provides a meager 100mA (the thing that you're always allowed to pull from every USB port ever, even if you don't negociate some fast charge) and thus the battery can very slowly be brought back above the threshold where it shuts down.

(e.g.: the OpenMoko is an example of phone which has such a behaviour. On the other hand various Motorola RAZRs always completely shut off the battery and require a specialized charger to bring it back to life).

I have no idea if the charging circuitry inside the Xperia X shows such behaviour.
