PROBLEM -
I Entered Advanced BIOS settig using Fn+Tab Key combination.
Then I enteres PCIE Configuration Setting.
By Default it was Desabled. I eabled it.
Then there were two options 1) PCIE PCH, 2) [i dont remember]
Then i choose PCIE PCH. Then Saved & Exit.

After that Laptop wont Boot.
Laptop Start But Nothing shown on screen (Black Screen) No Boot Menu Shown Nothing Shown.

Cant Enter BIOS using F2, to Reset The BIOS.
Display not even turn ON. I hear CPU Fan running Noise.
Caps Lock LED, Num Lock LED Not Working.

I dont hav any External Monitor to check if display is showing Through HDMI port.

Then i Googled it, and solution was to Reset BIOS,
by removing CMOS Battery for 10 Minutes.

Then, I opened Back panel, Removed The Main Battery, Then Removed CMOS Battery.
Kept it removed for 15 Minutes. Then Put back Main Battery first and then CMOS Bttery.

STILL PROBLEM IS NOT SOLVED.
So,
HOW TO RESET BIOS WHEN CANT ENTER BIOS?
Any Other Way To Reset BIOS, (Like Win+B Key Combination?)

Unplug the laptop, disconnect battery pack and remove the CMOS coin cell plug again. Then short the 2 motherboard CMOS pins with a screwdriver or jumper for about a minute. This should drain any residual charge on the BIOS chip and reset to default. Then button it back up and try it again.

What happens when you press FN+F6 and FN+F5?

Try pressing the hotkey Alt+ F10 during the boot-up process and follow the steps in the PDF file below, if your model has eRecovery or not this may get you to the Blue Screen of WindowsRE to restore or RESET the system.

If the screen isn't turning on, you can't use Alt-F10 without also knowing just how to move through menus without being able to see what you are doing. :)
