The laptop was turned off normally in the night. While I was trying to turn on it the next morning, it failed. The phenomenon is: the screen keeps totally black for 3seconds, and then it turns to very dark gray. Nothing appears on the screen (no words or the 'hp' logo) from beginning to end. The machine also makes the startup sound, it seems like the system is trying to start.

Some computers have an option in the BIOS or System Setup Menu to turn the laptop on at a particular time. It's a good feature for people who turn their laptops off at night because the first thing a computer does when you turn it on is to load all the startup software, then begin downloading and installing any updates it might have missed while it was turn off or start running a virus update or scan. That's why computer seem so slow when you first turn them on for about the first 10 to 20 minutes or so. So if I turn my computer off at night and I know my day gets started at 8:00am every morning, then I can set my computer to turn itself on every morning at 7:00am by itself. That way when I go to use it, it's good and fast.
you have over heated your machine as there was no ventilation possible damage to your cpu and bios chips these are all onboard mounted on the motherboard and as such the mother board will possibly have to be replaced would suggest you have professionally checked out
you have a BIOS bug when hibernation , leave without battery for few days try to turn on with the charger, and if turns on go to the battery settings and disable the hibernation option, later go to dell website and update your system BIOS.
please rate me
Bios firmware might have corrupted..goto dell website and enter ur service tag..u will see few recommended downloads for ur laptop....download the bios firmware and copy in it on to a cd/dvd/pendrive and then boot from cd/dvd/usb....
You tried your best in performing the first step (Leaving it out to dry)
But actually it is posible that the heat of the sun couldnt reach into some parts of the laptop and that some components must have been aftected before you came to its rescue
Apparently water or moisture was still resident in some internal part of the Laptop and this would have conducted some little spike of electricity that might have destroyed some components while it was connected to the AC.The flickers on the screen is an evidence of a possible spike from water or moisture.
Get a technician to open up the Laptop completely. He has to take a good look at each component carefully and clean them up.
Yes theres a possibility of your LCD being damaged but the VGA Card should be tested first.
Your Laptop would definitely come back to normal but not until each component is checked properly
