You press the power button and nothing happens: no lights, no beep, no hum. A hoverboard that won’t turn on is usually out of charge, has a loose connection or has a tired battery, and you can rule most of these out at home in a few minutes without opening anything.
Work through the checks below in order. They start with the easy, free fixes and end with the faults that need a replacement part or the manufacturer.
- If the board got wet, do not charge it or try to turn it on until it has dried out completely, ideally for a couple of days somewhere warm and dry.
- If the battery area is swollen, cracked, smells of burning or chemicals, or is hot, stop. Keep it away from anything flammable and do not charge it.
- Never open the battery pack itself. If you open the board’s shell to check connections, switch it off and unplug the charger first, and check your warranty, because opening it may void it.
This article is part of our hoverboard troubleshooting hub, which covers every common fault, from charging to calibration.
Quick checks: the first five minutes
- Charge it. A completely flat board will not power on at all. Plug in the charger and watch its light: on most chargers it turns red while charging and green when full. Give it at least an hour before you try again, and a full charge (usually two to four hours) if you can.
- Press the button the right way. Many boards need a single short press, but some need the button held for a second or two. Check your manual, and make sure you are pressing the main power button, not the light or Bluetooth button.
- Turn it on with your feet off the pads. Stand the board on a flat floor, keep the foot pads clear and press the button. If the pads are pressed while it starts up, some boards beep or refuse to start.
- Look for a separate power switch. A few models have a switch on the underside or the side in addition to the button. If yours does, make sure it is on.
- Warm it up. If the board has been in a cold garage or car, bring it inside and give it an hour or two at room temperature. Batteries that are very cold may not deliver enough power to start the board.
If it now turns on, it was almost certainly a flat or cold battery. If it still does not, find the symptom that matches below.
Fixes by symptom
No lights and no sound at all
Complete silence means no power is getting from the battery to the controller. The most common causes, roughly in order:
- The battery is flat or will not take a charge. If the charger light stays green when you connect it, the board is not accepting charge. Our guide to fixing a hoverboard that won’t charge walks through every charger-light pattern.
- A loose battery or power-button connection. A hard landing or a fall can shake a plug loose inside the shell. If you are comfortable opening the board, check that the battery connector and the power-button lead are pushed fully home. If you are not, this is a quick job for a repair shop.
- A failed power button. If the button feels different (mushy, stuck down or with no click), it may have failed. Replacement buttons are inexpensive, but fitting one means opening the board.
- A blown fuse. Some boards have a fuse between the battery and the controller. A blown fuse usually points to another fault, so it is worth having a repair shop or the manufacturer look at it rather than simply replacing it.
It only turns on while the charger is plugged in
If the board powers up with the charger connected but dies the moment you unplug it, the charger is doing the work and the battery is not. Either the battery has failed or the connection between the battery and the controller is broken. A worn-out battery is the usual cause on an older board; on a newer one, check the warranty first. Our battery replacement guide explains what a new battery involves.
It turns on, then switches off straight away
A board that starts and immediately shuts down is usually protecting itself. Low battery voltage, a fault reported by one of the sensors, or a board that is not level when it starts can all cause this. Charge it fully, start it on a flat floor with your feet off the pads, and if it keeps happening, try recalibrating it with our reset and calibration guide. If it shuts off during rides rather than at start-up, see our guide to a hoverboard that turns off randomly.
It beeps or flashes but will not start
Beeps and flashing lights are the board reporting a fault, and the pattern means different things on different brands. Count the beeps or note which light flashes, then look it up in your manual or in our guides to why a hoverboard beeps and hoverboard lights.
It stopped working after rain or a puddle
Water inside the shell can short the electronics or trip the battery’s protection. Switch it off, do not charge it, and let it dry thoroughly in a warm, dry room for a couple of days before you try again. If it still will not start, the controller or battery may be damaged, which is rarely covered by a warranty. If you ride in damp weather, our water-resistant hoverboard guide explains what the ratings actually cover.
The battery is old or was stored empty
A battery left completely empty for months, for example over the winter, can sink below the voltage at which its management system allows it to charge or power the board. Leave it on the charger while you are home and check whether the charger light changes within an hour. If nothing changes, the battery will most likely need replacing. Our guide to how long a hoverboard battery should last explains what is normal.
Charger, battery or board? How to narrow it down
| What you notice | Most likely culprit |
|---|---|
| Charger shows no light even on its own | Charger or wall outlet |
| Charger stays green when connected to a flat board | Battery, charge port or internal connection |
| Board works only while plugged in | Battery or battery connection |
| Charges normally but still won’t power on | Power button, internal connection, fuse or control board |
| Starts, then beeps and shuts off | Protection fault: battery voltage, sensor or calibration |
A borrowed charger with the same voltage and plug is the quickest way to separate a charger fault from a battery fault. If a known-good charger behaves the same way, the problem is inside the board.
When to contact the manufacturer or a repair shop
If the board is still under warranty, contact the manufacturer before you open it or buy parts; a battery or control-board failure on a newer board is their problem to fix. Outside the warranty, a repair shop can test the battery, the button and the control board, which is usually far cheaper than a new hoverboard if the board is otherwise in good shape. If you do replace the battery, never put the old one in household trash: tape over the terminals and take it to a battery recycling drop-off.
How to stop it happening again
- Charge after rides and never store the board completely empty; for a long break, leave it at about half charge and top it up every month or so.
- Keep it indoors at room temperature, away from freezing garages and hot cars.
- Avoid puddles and wet grass, and dry it off after damp rides.
- Use only the original charger or an exact-match replacement.
Frequently asked questions
Why won’t my hoverboard turn on after charging?
If the charger light turned green very quickly, the board probably did not take a charge at all, which points to the battery, the charge port or an internal connection. If it charged normally and still won’t start, the power button, a loose connector, a fuse or the control board is more likely.
How do I turn on a hoverboard without the power button?
On most boards you can’t; the button is the only way to switch it on. A few models can be switched on from a remote or app, but only if the board already has power. If the button has failed, it needs replacing.
Can a hoverboard battery be completely dead?
Yes. A battery that has been stored empty for a long time can fall below the voltage at which it will accept a charge, and an old battery eventually wears out. In both cases a replacement battery is the fix.
Should I reset my hoverboard if it won’t turn on?
Calibration only works on a board that powers up, so charge it first. If it turns on but beeps, shuts off or feels uneven, a reset and calibration is worth trying.
