How to Fix Laptop and PC Screen Remains Black After Power On
If the laptop and PC screen remains black or blank after start up, and there are no error messages on the screen, there may be a problem with the monitor or there may be a problem with graphic card.
To test for a defective display, follow the steps below.
1. Connect the computer external monitor or television set to motherboard integrated VGA port.
2. Connect the AC power to the laptop and external monitor.
3. Press the power button on the computer and external monitor.
If an image displays on the external monitor but not on the computer or laptop monitor, download and install the latest BIOS upgrade, the latest graphic card driver, graphic card BIOS upgrade, and the latest chipset driver. If there's still no image on the laptop or computer display, there is a hardware problem with the laptop or computer monitor.
If there is no image on either the laptop display or external monitor and the laptop does not start properly, this indicates a start up problem, not a display problem.
How to Resolve Laptop Not Powering On Issues
Perform a Hard Reset
If the computer suddenly fails to start up properly, perform a hard reset as the first action. Performing the hard reset will correct many problems.
1. To perform a hard reset, first disconnect all peripheral devices and remove all external storage and USB devices. Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 30 seconds to drain all residual power and restore default start up settings.
2. Reconnect the AC power adapter (but do not insert the battery), press the power switch. If the computer starts normally after performing a hard reset, you are done troubleshooting.
