PocketBook InkPad Color 3 · Troubleshooting
The PocketBook InkPad Color 3 won't turn on or is frozen
The screen is blank, stuck on the PocketBook logo, or frozen and not responding. Most cases are a flat battery or a software hang that a forced restart clears.
Symptoms
- Pressing the power button does nothing and the screen stays blank.
- The device is stuck on the PocketBook logo or a loading bar.
- A page is frozen and the buttons and touch do nothing.
- It froze while opening a large colour comic or PDF.
- It will not wake from sleep.
Before you start
- Use a charger and cable you know work, ideally the ones supplied.
- Give any charging attempt at least 30 minutes before deciding it is not working.
- A forced restart does not erase books or settings; a factory reset does.
Which fix do you need?
What is the device doing?
- Completely blank, no logo, no light Charge it first, then force a restart
- Stuck on the PocketBook logo or a loading bar Force a restart; if it recurs, check storage
- A page is frozen but the screen is on A forced restart clears the hang
- It freezes every time a particular file opens That file is the problem — remove it
Most common cause
The most common cause is a fully drained battery. The next is a software hang, where the device has power but has stopped responding, which holding the power button clears. On this device a very large or damaged colour comic archive or PDF is a common trigger for a freeze, because rendering a big colour page is heavy work.
Fixes
Fix 1 Charge it, then force a restart
A deeply discharged battery gives no response until it has taken on a little charge. Only after charging is a forced restart worth trying.
- Plug the InkPad Color 3 into a wall charger with a known-good USB-C cable and leave it for at least 30 minutes, longer if you can. A charging light or icon may not appear straight away.
- With it still plugged in, press and hold the power button for about 30 seconds. Keep holding through any menu that appears. The screen blanks and then shows the PocketBook start-up logo.
- Release and let it boot. After a full drain this can take a minute or two.
- If nothing happens after an hour on the charger and a 30-second hold, try a different cable and a proper wall charger before assuming a fault.
Fix 2 Force a restart to clear a hang or a stuck logo
If the screen is lit — a frozen page, or stuck on the logo — the device has power but the software has stopped. Holding the power button forces a clean restart.
- Press and hold the power button for about 30 seconds until the screen changes and the PocketBook logo appears, then release.
- Let it finish starting. A frozen reading session is usually back on the same page afterwards.
- If it hangs on the logo again, connect it to a computer, let it mount as a drive, and check there is free space. A completely full device can fail to start; delete a few large files, eject, and restart.
- If the logo hang repeats and the disk is not full, go to Fix 3.
Fix 3 Remove the file that triggers the freeze
A single oversized, damaged or oddly-encoded colour comic archive or PDF can hang the stock reader every time it is opened.
- Connect the device to a computer and remove the file you were opening when it last froze — usually the newest large colour CBZ, CBR or PDF.
- If you still want that title, try opening it in KOReader (it has a more robust engine), or re-download or re-export a clean copy.
- In Settings, run "Clear cache" or "Optimize library" / "Update library" to rebuild the book index without touching your files.
- As a last resort, a factory reset from Settings returns the software to new. It erases downloaded books and settings, so copy anything you want to keep off the device first.
Undo / recovery
A forced restart and a library rebuild leave your files in place. A factory reset erases downloaded books and settings but not your PocketBook account or cloud library, which can be re-synced after you sign in. If the device shows no response after an hour of charging, a fresh cable and charger, and a 30-second power hold, it is likely a hardware fault and worth contacting PocketBook support.

Follow the fixes in the order the decision tree points to. A long charge plus a 30-second power-button hold revives most unresponsive units; a stuck logo or frozen page is nearly always cleared by the same hold. If it freezes on one particular colour file, that file is the cause — remove it or open it in KOReader.
