When your computer suddenly refuses to turn on, it doesn’t always mean it’s broken. Many times, the issue is something simple that you can check on your own. Before sending it for repair, try going through these five quick checks.
1. Make sure the power source is working
Check whether the power outlet has electricity. Try plugging in another device or switching to a different socket. Sometimes the problem isn’t the computer—it’s the power source.
2. Inspect the power cable and adapter
Loose or damaged cables can stop your computer from turning on. Ensure every connector is firmly plugged in and the adapter light (if any) is on.
3. Try removing the battery (for laptops)
If you’re using a laptop, remove the battery (if it’s detachable), wait a few seconds, then reconnect the charger only. A faulty battery can prevent the laptop from powering up.
4. Look for signs of overheating
If the computer was very hot before shutting down, it may have triggered an automatic protection mode. Let it cool for a few minutes and try again.
5. Check for peripheral issues
Sometimes USB devices, external drives, or accessories can interfere with startup. Disconnect everything except the charger or power cable and try turning it on.
In summary：
Many startup issues are caused by simple power or connection problems. By checking these five points first, you might solve the problem yourself and save time on unnecessary repairs.
