If your computer won’t turn on, you can try these steps:
- Check power connections: Make sure the power supply cable is plugged into the power supply and outlet, and that the wall outlet is active. You can also check for loose or damaged cables inside your computer case.
- Check the power button: If your motherboard has an onboard power button, check it. You can also unplug the connector from the motherboard and check for damage.
- Perform a hard reset: A hard reset can help drain residual power that can cause boot problems.
- Remove external devices: Disconnect any external devices, such as USB drives, external hard drives, and your mouse and keyboard.
- Reset BIOS to defaults: Resetting the BIOS can help troubleshoot the problem.
- Check the power supply and battery: If you have a laptop, check that the battery isn’t completely run out of charge. If you have a desktop computer, try plugging it into a different outlet.
- Check for hardware issues: If you’ve recently installed new hardware, try removing it.
Laptops can be a little more difficult,
To drain a laptop’s residual power, you can perform a hard reset, which is also known as a residual power drain:
- Turn off the computer
- Unplug the power adapter, Remove the Battery if Possible
- Press and hold the power button for about 20-30 seconds
- Reconnect the power adapter (ideally leave Battery disconnected)
- Turn on the computer if this boots normally shutdown the computer and add the battery then start the laptop as normal.
Residual power is the power that remains in a computer’s capacitors after it’s been powered off. It’s also known as “flea power” because it’s static electricity. Draining residual power can help fix performance issues and is necessary before removing or replacing any components.
