You are having trouble turning on your computer what should you do first

If you are having trouble turning on your computer, here are a few steps you could try as a first troubleshooting measure:

1. Check the power source: Ensure that your computer is properly connected to a power outlet or that the battery is charged if you are using a laptop. Try using a different power outlet or a different power cable to eliminate any issues with the power source.

2. Check the power button: Ensure that you are pressing the power button correctly and giving it enough time (a few seconds) to initiate the boot process. Some computers may have a separate power button on the back or side as well, so make sure both buttons are functioning properly.

3. Disconnect external devices: Remove any external devices such as USB drives, printers, external hard drives, etc., from your computer. Sometimes, a faulty or incompatible external device can prevent the computer from booting.

4. Check for any indicator lights: Check if there are any LED indicator lights on your computer that show power or connectivity. If these lights are not turning on or behaving unusually, it might indicate an issue with the power supply or other hardware components.

5. Perform a hard reset: If none of the above steps work, try doing a hard reset by completely shutting down your computer, disconnecting it from the power source, removing the battery (if possible), and then holding down the power button for about 15-20 seconds. After that, reconnect the power source and try turning it on again.

If these initial steps do not solve the problem, it might be necessary to seek further technical assistance from a professional or contact your computer manufacturer's support.
