Start with the simplest fixes first
A tablet that won't turn on or charge usually has a fixable problem. Before you assume the device is broken, try these three things in order: charge it for at least 30 minutes using the original charger, force a restart by holding the power button for 10 to 15 seconds, and inspect the charging port for lint or debris. Most tablets that seem dead are actually just deeply drained, stuck in a frozen state, or blocked by something as small as pocket lint.
The order matters because each step rules out a different cause. If your tablet charges after 30 minutes, the battery was straightforward depleted. If it restarts after a force-restart, the software froze. If cleaning the port works, you found the culprit. Work through them one at a time so you know which problem you actually have.
Key Takeaways
- Charge your tablet for at least 30 minutes with the original charger before assuming it is broken, because deeply drained batteries can take time to show any sign of life.
- Force a restart by holding the power button for 10 to 15 seconds—this unfreezes a tablet that is powered on but unresponsive.
- Clean the charging port with a dry toothpick or soft brush to remove lint, which blocks the connection between charger and device.
- Test with the original charger first, because third-party chargers may not deliver enough power or may be incompatible with your tablet model.
- If the tablet still will not respond after these steps, the battery, charging circuit, or power button may need professional repair.
How to charge a completely dead tablet
A tablet with a completely empty battery shows no signs of life—no screen light, no vibration, no sound. This is normal. Plug it into the original charger and leave it alone for 30 minutes before trying anything else. Some tablets take 15 to 20 minutes just to accumulate enough charge to display a charging indicator on the screen.
Use the charger that came with your tablet, not a phone charger or a generic USB charger. Tablets draw more power than phones, and a weak charger may not deliver enough current to wake the device. If you have lost the original charger, look up your tablet model number (usually on the back or in Settings) and buy a replacement with the same voltage and amperage—these numbers are printed on the charger itself.
After 30 minutes, plug in the charger and watch for a light on the device, a vibration, or a logo on the screen. If you see any of these, the battery is charging. Leave it plugged in for another hour or two before trying to turn it on. If you see nothing after 30 minutes, move to the next step.
Force a restart when the tablet is frozen
A tablet that is powered on but will not respond to touches or button presses is frozen, not dead. Force it to restart by holding the power button down for 10 to 15 seconds without letting go. You may see a power-off screen or a logo appear—keep holding. The tablet will vibrate or the screen will go black, then it will restart.
This works because a frozen tablet is stuck in software and needs to be shut down completely and rebooted. A normal power-off button press does not always work when the system is frozen. The long hold forces the device to cut power when ready, which clears the frozen state.
After the restart, the tablet should boot normally and ask for your password or PIN. If it restarts and then freezes again when ready, the problem is likely a software issue or a corrupted app, not a hardware problem. In that case, you may need to restore the tablet to factory settings, which erases all data—back up anything important first if you can.
Clean the charging port to restore the connection
Lint, dust, and debris inside the charging port prevent the charger from making contact with the device. Look into the port with a flashlight. If you see fuzz or buildup, that is the problem. Use a dry toothpick, a wooden skewer, or a soft brass brush to gently scrape the inside of the port. Do not use metal objects like paper clips, which can scratch the contacts and cause permanent damage.
Work slowly and carefully. The contacts inside the port are small and fragile. Scrape gently along the sides and bottom of the port, then blow out any loose debris with your mouth or a can of compressed air. Do not use a wet cloth or liquid cleaner—moisture inside the port can cause corrosion or short circuits.
After cleaning, plug in the charger and check for a charging light or indicator on the screen. If the tablet now charges, you have solved the problem. If it still does not charge, the port itself may be damaged, or the problem is inside the device.
Test the charger and cable separately
A broken charger or cable looks fine from the outside but does not deliver power. If you have access to another tablet that uses the same charger, plug that tablet in and see if it charges. If the other tablet charges, your charger is working and the problem is with your tablet. If the other tablet does not charge, the charger or cable is broken.
Inspect the cable for visible damage—bent connectors, cracked plastic, exposed wires, or burn marks. Even small damage can prevent charging. If the cable looks damaged, it needs to be replaced. If the cable looks fine but the charger does not work on another device, the charger itself is faulty.
If you do not have another tablet to test with, borrow a charger from a friend who has the same model, or visit a store that sells your tablet brand and ask to test your tablet with a display model's charger. This takes five minutes and tells you definitively whether the charger is the problem.
Check for water damage or physical damage
If your tablet has been dropped, sat on, or exposed to water, internal damage may prevent it from turning on or charging. Look for these signs: water inside the screen, cracks in the case, a bent frame, or corrosion around the charging port (a white, green, or blue crusty buildup). If you see any of these, the tablet likely needs professional repair.
Some tablets have a water-damage indicator inside the charging port or under the battery—a small sticker that changes color if exposed to moisture. If you can see into the port with a flashlight, look for a white or light-colored sticker. If it is pink, red, or dark, the tablet has been exposed to water at some point, even if you do not remember it happening. Water damage can cause charging and power problems that develop days or weeks after the exposure.
If you suspect water damage, do not keep charging the tablet, because electricity and moisture together can cause short circuits. Let the tablet dry completely in a warm, dry place for 24 to 48 hours before trying again. Do not use a hair dryer or oven, which can damage the screen or battery.
When to seek professional repair
If you have tried all the steps above and the tablet still will not turn on or charge, the problem is likely inside the device. The battery may be dead and unable to hold a charge, the charging circuit may be damaged, the power button may be broken, or the motherboard may have failed. These problems require opening the device and replacing parts, which is not safe to do at home.
Contact the tablet manufacturer's support line or visit an authorized repair center. Bring the tablet and your proof of purchase if you have it. Repair costs vary widely depending on the problem and the tablet model—a battery replacement might cost $50 to $150, while motherboard repair can cost $200 or more. Some repair centers offer a free diagnostic, which tells you exactly what is wrong before you commit to paying for the fix.
If the tablet is still under warranty, the repair may be covered at no cost. Check your purchase receipt or the manufacturer's website to see when your warranty expires.
Frequently Asked Questions
How long should I charge a dead tablet before I try to turn it on?
Charge for at least 30 minutes with the original charger. Some tablets take 15 to 20 minutes just to show a charging indicator. If you see no sign of life after 30 minutes, charge for another hour before giving up. Do not try to force it on by holding the power button—let the battery accumulate charge first.
Can I use a phone charger to charge my tablet?
Phone chargers deliver less power than tablet chargers. Your tablet may charge very slowly or not at all. Use the original charger whenever possible. If you must use a different charger, make sure it has the same voltage (usually 5V to 12V) and equal or higher amperage (measured in amps or A) as the original.
What does it mean if my tablet gets hot while charging?
Tablets warm up during charging, especially if you are using them while plugged in. Mild warmth is normal. If the tablet is too hot to touch, or if it shuts itself off due to heat, unplug it when ready and let it cool for 30 minutes. This can indicate a faulty charger, a damaged battery, or a problem with the charging circuit. Do not keep charging a hot tablet.
Will factory resetting my tablet fix a charging problem?
No. A factory reset erases all your data and reinstalls the operating system, but it does not fix hardware problems like a broken charger, a damaged port, or a dead battery. Only do a factory reset if the tablet turns on and freezes repeatedly, which suggests a software problem. Back up your data first.
Is it safe to leave my tablet plugged in overnight?
Modern tablets have built-in protection that stops charging once the battery reaches 100 percent, so leaving it plugged in overnight will not damage the battery. However, leaving any device plugged in for extended periods generates heat, which can shorten battery life over time. Unplug the tablet once it is fully charged if you plan to leave it unused for more than a few hours.
