Start with the battery and charging port
A Samsung tablet that won't turn on usually has a dead or nearly dead battery. Plug the tablet into its original charger and leave it connected for at least 30 minutes before trying to power it on again. Many tablets shut down completely when the battery drains past a certain point, and they need time to accumulate enough charge to respond to the power button.
While charging, look at the charging port on the bottom or side of your tablet. If you see lint, dust, or corrosion inside the port, use a flashlight to inspect it closely. Do not insert anything metal into the port. Instead, use a wooden toothpick or a plastic dental pick to gently remove debris. If the port looks corroded or damaged, the tablet may not charge at all, and you will need to address that separately.
After 30 minutes of charging, press and hold the power button for 10 to 15 seconds. The power button is usually on the right edge or top of the tablet. You may see a Samsung logo or vibration before the screen lights up. If nothing happens, continue charging for another hour and try again.
Key Takeaways
- Leave your tablet plugged into its original charger for at least 30 minutes before attempting to power it on, since a completely drained battery may not respond when ready.
- Check the charging port for lint or debris using a wooden toothpick, and inspect the cable and power adapter for visible damage or burn marks.
- If the tablet shows a charging light or vibrates when plugged in, the battery is responding; if it shows nothing, the charger or port may be faulty.
- A force restart using the power and volume buttons together can wake a frozen tablet even when the screen appears completely dead.
- If your tablet still will not turn on after charging and a force restart, the battery or motherboard may need professional repair.
Try a force restart if the tablet is frozen
If your tablet is plugged in and charging but the screen remains black and unresponsive, it may be frozen rather than truly off. A force restart can wake it. The button combination varies by Samsung model, but the most common method is to press and hold the power button and the volume down button together for 10 to 15 seconds. Hold them even if you see nothing on the screen.
Some older Samsung tablets use power plus volume up instead. If you are unsure which combination your model uses, look up your specific tablet model number (found in Settings > About Tablet on a working device, or on the back of the tablet) and search for "force restart [model number]." Samsung's support site lists the exact button combination for each model.
When the force restart works, you will usually see the Samsung logo appear, followed by the lock screen. The tablet may take 30 seconds to a minute to fully boot up after a force restart, so wait before pressing anything else.
Check the charger and cable for damage
The charger itself may be the problem. Inspect the cable for cuts, fraying, or kinks, especially near the connector ends. Look at the power adapter (the brick that plugs into the wall) for burn marks, discoloration, or a burnt smell. If you see any of these signs, stop using that charger when ready—a damaged charger can harm the tablet or create a fire risk.
Try borrowing a charger from a friend with the same Samsung tablet model, or purchase a replacement charger that matches your tablet's specifications. The charger specifications are printed on the back of the original adapter (usually something like "19V 2.1A" or similar). Using a charger with the wrong voltage can damage the tablet's battery.
If the tablet charges with a different charger but not the original one, the original charger is faulty. If the tablet still will not charge with multiple chargers, the charging port or battery inside the tablet may be damaged.
Look for signs the tablet is actually responding
Before assuming the tablet is broken, watch for small signs that it is receiving power. When you plug it in, look for a small LED light near the charging port—many Samsung tablets show a light when charging. Some tablets also vibrate briefly when plugged in, even if the screen stays black. These signs mean the tablet is getting power and the battery is responding.
If you see a charging light or feel a vibration, the tablet is likely working but the screen is not turning on. This usually means the battery needs more time to charge, or the display itself has a problem. Leave it plugged in for several hours and try the force restart again.
If you see no light, feel no vibration, and the tablet stays completely unresponsive after an hour of charging, the charger, port, or battery is likely faulty and may need professional service.
Perform a hard reset if the tablet boots but freezes
If your tablet turns on and shows the Samsung logo or lock screen but then freezes or gets stuck on a loading screen, a hard reset may help. This is different from a force restart—a hard reset clears the tablet's temporary memory and can fix software problems that prevent booting.
To perform a hard reset, press and hold the power button and volume up button together for 10 to 15 seconds until you see the recovery menu (a screen with text options). Use the volume buttons to navigate to "Wipe cache partition" and press the power button to select it. This clears temporary files without erasing your photos or documents. After it finishes, select "Reboot system now."
If the tablet still freezes after a cache wipe, you may need a factory reset, which erases all data on the tablet. Only do this if you have backed up your important files. In the recovery menu, select "Wipe data/factory reset," confirm the action, and wait for the process to finish. The tablet will restart and ask you to set it up as if it were new.
When to seek professional repair
If your tablet still will not turn on after charging for several hours, trying a force restart, and testing with a different charger, the problem is likely inside the tablet. Common internal issues include a failed battery, a damaged charging port, or a motherboard problem. These require professional repair and are not something you can fix at home.
Contact Samsung support or visit an authorized Samsung service center. Bring your tablet and charger so the technician can test both. If your tablet is still under warranty, the repair may be covered at no cost. If the warranty has expired, ask for a repair estimate before authorizing any work.
If the tablet is very old or the repair cost is high, you may decide it is more practical to replace it. A technician can tell you whether repair or replacement makes more sense for your situation.
Frequently Asked Questions
How long should I charge a completely dead Samsung tablet before trying to turn it on?
Charge for at least 30 minutes before your first attempt, then try a force restart. If nothing happens, continue charging for another hour or two. Some tablets take several hours to accumulate enough charge to respond, especially if the battery has been completely drained for weeks.
What does it mean if my tablet vibrates when plugged in but the screen stays black?
The vibration means the tablet is receiving power and the battery is responding. The screen may not turn on because the battery is still too low, the display is broken, or the tablet is frozen. Leave it charging for several hours and try a force restart with the power and volume buttons.
Can I use any charger with my Samsung tablet?
No. Use only a charger that matches your tablet's voltage and amperage specifications, which are printed on the original adapter. Using the wrong charger can damage the battery or motherboard. If you need a replacement, buy one from Samsung or a certified retailer.
Will a hard reset erase my photos and files?
A cache wipe will not erase your data. A factory reset will erase everything on the tablet. Only perform a factory reset if you have backed up your important files to a computer or cloud storage first.
What should I do if the charging port looks damaged or corroded?
Stop using that charger and do not force the cable into the port. A damaged port cannot charge the tablet safely and may need to be replaced by a professional. Take the tablet to an authorized Samsung service center for inspection and repair.
