Do you have no display on your PC or Laptop?
Is your desktop computer or laptop giving you a no-display signal, black-lit screen, or no-lit screen? Some of the causes of this could be simple issues and some could be stressful to troubleshoot but we’ve got you covered.
Causes
For starters, we must ask what could cause a problem like this. Just like with a desktop PC connected to a monitor, the laptop monitor is connected to the motherboard with a cable. The cable may be bad, or it could be loose. Your computer may not be functioning correctly because of a static electricity build-up.
If you have a laptop, you may have a problem with one of the integrated circuits on the board, which is not exactly an issue for the casual user. Just keep in mind that everything may not be within your reach but there are still many things to try before jumping to the worst conclusion like a bad screen or electrical problem. For example, you may have other bad hardware preventing your computer from turning on fully. Two common pieces of hardware that people upgrade or have issues with are their RAM or storage drives.
Troubleshooting
Here are some troubleshooting tips :
-
- First, check if the computer is actually turning on. Can you hear fans? Are there any indicator lights on the computer that suggest it’s on? If you happen to have a flashing light somewhere, that could be an error indicator. Check with your computer’s manufacturer to see if the flashing lights are indeed error codes.
-
- Now, if the computer seems like it’s turned on and there are no flashing lights, Try holding the power button with the charger or power cable disconnected to drain the computer of any remaining static. Now try turning the computer back on. If it’s a laptop, try without the charger first.
-
- Try connecting a secondary monitor to your laptop. If it works, your monitor may be bad. Sometimes, it won’t work at all depending on the manufacturer. We know Dell computers won’t start properly at all if the monitor isn’t working.
-
- If you have a desktop PC, try using a different monitor cable. And please check if you are connecting the cable on your computer’s motherboard or if you are using the computer’s GPU ports if it has them. The computer will not function correctly if you connect to your motherboard when a GPU is installed.
