Acer Aspire 4451-2368 won't show anything on screen

@chaos85342 you first need to determine if it indeed turns on. Connect an external monitor and see what that displays. If you can now see your desktop etc, you know the issue will be related to your LCD.

If you still do not see anything, then it is possible that you either have a BIOS issue, or your computer does no longer have access to the software (i.e. harddrive /SSD failure0.

Let us know what you find out.

Hi @chaos85342

Please confirm the model number of your laptop?

I can't find any information on an Acer Aspire 4451 only a ZX4451 and there's not much on it either.

Is it an Acer Aspire 4551 by any chance?

Note: If your model is an Acer 4451 then the following may still apply to your model as well.

It may be possible that corrupted BIOS setting(s) are preventing normal operation and startup.

Try a power refresh by disconnecting the charger, removing the main battery then opening the laptop and disconnecting the backup battery (aka cmos or RTC battery) from the motherboard and then press and hold the Power button operated for 15-20 seconds.

Reconnect and reassemble everything, connect the charger and check.

Here's an image taken from this teardown video showing the location of the RTC coin cell battery in a 4551 model

If the battery is >4-5 years old, replace it. The part number should be on the battery itself.
