If your computer does not power on, here are some steps you can take to provide first aid:
- Check the power source: Make sure that the computer is properly plugged in and that the power source is working. You can check this by plugging in another device, such as a lamp, to see if it turns on.
- Check the power cord: Make sure the power cord is properly connected to the computer and the power source. You can also try using a different power cord to see if that solves the issue.
- Check the power supply: If you have a desktop computer, check the power supply unit (PSU) to see if it’s working. You can do this by checking the fan on the back of the PSU to see if it’s spinning. If it’s not spinning, the PSU may be faulty.
- Check the battery: If you have a laptop computer, check the battery to see if it’s properly charged. You can also try removing the battery and plugging the laptop into a power source to see if it turns on.
- Check the hardware: If none of the above steps work, there may be a hardware issue with the computer. You may need to take the computer to a professional for further diagnosis and repair.

It’s important to note that working with computer hardware can be dangerous, so if you’re unsure about what you’re doing, it’s best to seek professional help.
