Why does my Acer Aspire E15 screen turn off when the power supply is connected?

Your Acer Aspire E15 might have a hardware fault, possibly within the GPU or power supply system. Here are some suggestions for diagnosing the issue:

1. Test with another compatible power adapter to see if the issue persists.
2. Boot the laptop in Safe Mode to observe if the problem occurs. If not, it might be a software or settings conflict.
3. If neither solution works, consult a technician for a detailed hardware inspection, as this could be an internal fault.

Addressing these points could potentially highlight the root cause of the screen issue.

Overheating might be causing your Acer Aspire E15 screen to shut off when charging. To address possible overheating:

1. Clean your laptop’s vents and fans to remove any dust.
2. Use a cooling pad to help keep temperatures down.
3. Monitor system temperatures using a tool like HWMonitor. If temperatures exceed safe limits, it might be time to reapply thermal paste or get a professional cleaning of the cooling system.

Taking these steps could alleviate overheating issues causing the screen to turn off when the power supply is connected.

You might be dealing with a hardware issue like a malfunctioning charging port or faulty battery. Follow these steps:

1. Carefully wiggle the power connector gently at the port end to see if the screen flickers or stays on.
2. Open your laptop’s back cover and ensure all internal cable connections, particularly for the display and battery, are secure.
3. Check the power connector and port for visible damage or looseness.

These checks can help confirm if the problem is with the hardware connections.

It’s likely a power setting problem on your Acer Aspire E15. Here’s how you can check and adjust the settings:

1. Right-click the battery icon on the taskbar, and select ‘Power Options’.
2. Beside your selected power plan, click ‘Change plan settings’.
3. Select ‘Change advanced power settings’.
4. Go to the ‘Display’ section and expand it.
5. Ensure ‘Turn off display after’ is set to ‘Never’ for when the laptop is plugged in.

These steps can help ensure that the display remains active when the power supply is connected.

The issue could be due to driver conflicts or bugs in the power management software. Here’s what you can do:

1. Open ‘Device Manager’ by pressing ‘Windows + X’.
2. Expand ‘Display adapters’ and right-click your graphics driver, then select ‘Update driver’.
3. Consider rolling back to a previous, stable driver if updating doesn’t solve the issue.

Review your power management settings as well, ensuring there are no configurations causing this problem. This might resolve conflicts impacting the screen behavior.
