If your Google Pixel 10 Pro is completely black and won't respond, the first thing to try is a force restart. This is different from just tapping the power button. Press and hold the Power button and the Volume Up button together for about 10 seconds. Keep holding them until you see the Google logo appear on the screen, then you can let go.
This forces the phone to shut down and reboot from scratch, which can clear out temporary software glitches that are preventing it from starting normally. I'd start with this one, as it resolves a lot of unresponsive phone issues without affecting any of your data or settings.
Check Your Charger and Cable
Your Pixel might have a completely drained battery. Plug it into a wall outlet using the official Google 30W charger and a known-good USB-C cable. Let it charge undisturbed for at least 30 to 45 minutes before trying the force restart again.
A completely flat battery can sometimes take a few minutes of charging before it will even show a charging indicator on the screen. Don't rely on a computer's USB port or a low-power charger for this initial boost, as they often don't provide enough power to wake a deeply discharged battery.
It's worth checking the physical USB-C port on the bottom of your Pixel 10 Pro. Lint and pocket debris can compact over time, preventing the cable from making a solid connection. Gently clean it out with a can of compressed air or a plastic toothpick, being very careful not to damage the delicate pins inside.
Try a Different Power Source
If you don't have the official charger handy, try another high-quality USB-PD (Power Delivery) charger that supports at least 18W. Some third-party chargers, especially older or cheaper models, may not properly negotiate the fast charging protocol with the Pixel and won't deliver enough power.
You can also test wireless charging. The Pixel 10 Pro supports Qi2, so place it centered on a compatible wireless charger. Remove any thick or metal phone case, as it can block the charging coils. A good wireless pad should also be able to provide enough juice to wake the phone from a dead state, though it will be slower than wired.
If the phone gets unusually warm to the touch while charging, it may have entered a thermal protection mode. Fast charging will throttle under high temperature conditions. Try moving it to a cooler surface and use a standard, slower charger for a while to see if it recovers.
Boot Into Recovery Mode
If the force restart didn't work and the phone has had ample charge time, you can try accessing the recovery menu. First, make sure the device is powered off. Then, press and hold the Power button and Volume Down button together.
When you feel the phone vibrate or see the bootloader screen (a screen with an Android robot and "Start" text), use the Volume buttons to highlight "Recovery mode" and press the Power button to select it. You'll see an Android robot with an exclamation mark. From here, press and hold the Power button, then tap the Volume Up button once and release both.
This menu lets you clear temporary system files. Use the volume keys to navigate to "Wipe cache partition" and select it with the power button. This deletes cached data from apps and the system that can sometimes become corrupted, without touching your personal photos, messages, or apps.
Consider a Factory Reset
This is a last resort, as it will erase all data from your Pixel 10 Pro and return it to its original out-of-the-box state. You should only proceed if you have a recent backup or have accepted that your data may be lost.
You can initiate this from the same Recovery Mode menu mentioned in the previous step. Navigate to "Factory data reset" or "Wipe data/factory reset" and confirm your selection. The phone will take several minutes to complete the process and then reboot.
If the phone is so unresponsive that you cannot access Recovery Mode using the button combinations, you may need to use Google's Android Flash Tool on a computer. This requires enabling USB debugging beforehand, which isn't possible if the phone won't turn on at all, making the hardware checks your primary path forward.
