This article is only applicable if your computer fails to display a screen upon start-up, but the power indicator light is on. If you have performed any of the following steps before encountering this issue, please refer to this article for further instructions.
Note: If you have not performed any of the following steps and your computer fails to power on, please refer to this article: Troubleshooting - Notebook cannot power on and shows black screen.

• Disconnect or replace the battery.

If you have performed any of the above three scenarios, the computer will need to complete a full memory training upon the next power on.

During the memory training process, there will be no display on the screen, and the training will take approximately 1 to 3 minutes, depending on the size of your computer's memory.

During this time, please ensure that your computer is connected to a power source and do not force shut down, allowing the computer to complete the memory training and wait for the screen to appear.

If there is still no display after waiting for more than 3 minutes, please refer to this article for further troubleshooting: Troubleshooting - Notebook cannot power on and shows black screen.
