The computer does not power on when the power button is pressed.

If your device is not connected to an AC adapter and will not turn on, you may need to charge your battery. Plug the AC adapter into the charging port on the device, ensuring that the indicator light turns on. If the charging indicator light does not turn on, your AC adapter may be faulty.

If the charging indicator light on your device does not turn on when you plug your AC adapter into it, your AC adapter might be faulty. To check it, follow these steps:

1. Unplug your AC adapter first from your computer, and then from the wall socket.
2. Ensure the power cable is properly and securely connected to the adapter box.
3. Inspect the cables for bends, breaks, or exposed wire. If any are found, you may want to consider replacing your AC adapter.
4. Remove the battery from your device.
5. Plug the power cable attached to the AC adapter into a wall socket, and plug the adapter into the device charging port.
6. Attempt to power on your device. If it will not power on, consider purchasing a replacement AC adapter.

Note that if your device will power on only when the AC adapter is plugged in, you may have a faulty battery.

If your device will only power on when the AC adapter is connected, your battery might no longer hold a charge. To test this, turn off the device and leave the AC adapter connected for the standard charging time. Then, disconnect the AC adapter and attempt to turn the device on. If this fails, you may need to replace your battery. Learn how to do so here.

Device battery is not receiving or maintaining power.

If your device’s charging indicator light is on, and the device will power on only when the AC adapter is connected, you may have a faulty battery. To replace it, follow these instructions.

If your device’s battery is not charging, you may have a faulty AC adapter. First, disconnect the adapter from the wall socket and from your device. Inspect all cables for signs of damage, bends, or breakage. If any are found, consider replacing your AC adapter. If the adapter appears to be in good shape, ensure the power cable is securely connected to the adapter box. Plug the adapter’s power cable into a working wall socket, then connect the adapter to your device’s charging port. Check to ensure the charging indicator light has turned on. If no light appears, you may have a faulty AC adapter.

If your device’s charging indicator light is on, but your device will not hold or maintain a charge, the device’s battery may be faulty.

No sound plays from device speakers or accessory connected to headphone port.

If no sound is playing from your device’s speaker or from an accessory plugged into the headphone port, the device volume might be muted. To check this, right-click the volume icon in the lower right corner of your screen, and select “volume mixer”. Ensure that your device volume is set to the level of your choice, and close the window.

If your device is not muted and still emits no sound through the speakers or an audio device connected to the headphone port, your drivers may be faulty or out-of-date.

If no sound is coming from a connected accessory or the device’s speakers, your sound drivers may be out of date or faulty. To update them, follow these instructions:

2. Press the Windows logo key. Type “check for updates” in the search box, and press enter.
3. On the “Windows Update” screen, click “Check for Updates”.

Once your drivers have been updated, restart your device using the shutdown menu. If your device is not muted, the drivers are up-to-date, and there still is no sound from the speakers or an accessory connected to the headphone port, you may have faulty hardware.

If your device is not muted, the drivers are up-to-date, and there is either no sound or crackling noise coming from your device’s speakers, the speakers may be faulty, and will need to be replaced. Learn how to replace them here.

If sound comes from your device’s speakers, but not from an accessory connected to the headphone port, your accessory audio device may be faulty. Try plugging in a different but similar audio accessory. If this accessory works, consider replacing the non-working audio accessory.
