Windows 10: Laptop booting with no display

I got this hp aspire 3-21-40al a315 laptop that's booting with no display, I disconnected everything and reconnected but still no display not even through external via hdmi, would a dead board be the issue?

:)

 

Laptop display question

Confusing statement! You want to change the display on your laptop that died?

Is that correct?

How do you know its the display that's bad?

Just google "how to change display on a acer 5745"

Should get you to step by step instructions. But first make sure its the display that's bad

 

Laptop display does not detect itself

Hi,

• Go to Settings.
• Click on System.
• Under System, choose Display.
• Under Multiple displays, click on Duplicate these displays and apply.

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
