Laptop screen delay in lighting up

[Khristeen]

Since after accidentally dropping my Dell laptop, there has been delay in the showing of Dell logo after turning the power on. Before the incident, the screen usually lighted up with the brand logo immediately after pressing the power button. Now it takes a minimum of 5 seconds to wake. I'm sure that this has something to do with an internal damage from the accident. The system responds normally though after booting. My screen suffers from backlight bleeding so I know the fix for this is to replace the LCD.

I'm wondering, where is the delay issue coming from? To make myself clearer, which part of the laptop is disrupted and causes the screen to delay in lighting up?

Please help.

If the device is no longer under warranty, then I would consider opening it up and then disconnecting and reconnecting the cable that connects the display.
