HP Mini Blank Screen Problem

[ImmortalPhenex]

My HP Mini 210-1084TU suddenly got disconnected from charging socket and turned off(Battery was Low).

Next time i Boot up, the screen lits up but something was written and it nothing happened for 3 Hrs so i turned it off.

Next day I Started my laptop again but the screen doesnt lit up at all. Only the caps light is on continuously(No Blink). Fans are spinning and laptops get heated too but no screen. I have kept laptop running overnight but still no screen!

Here what i have checked so please help me:

1. Removed Battery and Adapter try to reset to start it up.
2. Removed RAM and cleaned it and Inserted it again. 
3. tried Booting up latop without RAM to check if Caps lock light gives right blink code. Which it does(3 Blinks)
4. Replaced RAM with another and tried booting up.
5. Remove and then reattach hard drive.
6. Replaced with another HDD and tried running the laptop. Still no changes.
7. Since, My current HDD was replacement, I tried using the stock(Which is totally corrupted) and it just gives me a lot of beeps
8. Removed Hard Drive and tried booting up. (Surprisingly it didnt give any error in caps lock)
9. Removed CMOS Battery and waited 1 minute before pushing it back in to see if it turns on. No luck.
10. tried Esc, Delete, f12,f10 and Etc.
11. Windows + B also didnt work. But one interesting thing i found out while doing this is there are some activites shown in Hard Drive indicator from time to time. Also, when Android device is connected in this mode, it gives option to connect as File Transfer/other options but when normally booting up, it doesn't give me such options.(just Charges and doesnt recognizes laptop)

I Guess this much diagnose should be enough, if there are more please tell me so that i can find out what's the problem!

Also, I have already tried the method that someone else posted in other thread but it didnt work out for me.

Please help if you know what can i do to fix it up. Also, i dont have access to any Projector so i cant verify of the display is dead or not.

Ok. I will try it. Also, I would like to add that, i just tested connecting to external display and it doesnt work. And when pressing Win+B option and connectting a PEn Drive with an LED indicator, i found that after some secnonds there is some activity on en Drive and then it closes the connection(No Light). If there is a way to fix it by flashing BIOS thgen please help em cause I am just able to download and Exe file and not make bootable drive out of it!
