🖥️ Computer Not Turning On? Try These Fixes First

When your computer suddenly won’t power on, it can be stressful — especially when you’re mid-task. But not all power issues are serious. Sometimes, it’s a simple connection or device conflict causing the problem.

Here are a few quick checks you can do before getting in touch with support.


🔌 1. Check the Power Connection
Ensure the power cable is firmly plugged into both the device and the wall.
Try a different outlet, and avoid power boards or surge protectors during testing.
For laptops: Test with another charger if available.
For desktops: Make sure the PSU switch on the back is turned on.


🔘 2. Hold the Power Button
Press and hold the power button for 5–10 seconds.
Look for lights, fan sounds, or screen flickers — any sign of life.
If nothing happens, it may be a hardware or internal issue.


🔁 3. Try a Different Power Outlet
The wall socket might be the issue.
Move to a different power point, ideally in another room.
Avoid using extension leads while testing.


🧩 4. Remove External Devices
Unplug all USB drives, monitors, printers, dongles, and accessories.
Faulty or stuck peripherals can interrupt startup.
Try powering the computer on again with nothing connected.


🔍 5. Look and Listen for Signs of Power
Check for fan movement or indicator lights.
For laptops: Shine a torch at the screen — a faint image might mean a screen backlight issue, not a full system failure.


🔋 6. Reset the Battery (Laptops Only)
If your laptop has a removable battery:

  • Remove the battery and unplug the charger

  • Hold the power button for 20 seconds

  • Reconnect the battery and charger

  • Try powering it back on

If the laptop only turns on when plugged in, the battery could be the issue.


🧼 7. Clean Out Dust (Desktop PCs)
Dust can block ventilation, causing the system to overheat or shut down.
Use compressed air to gently clean the vents and fans.
Only open the case if you’re confident handling hardware safely.
