1 Display won't turn on, battery indicator flashes white.
Context:
I left my laptop on overnight, and it shut itself down from low battery by the time I woke up. Perfectly normal, I've done that multiple times. Laptop worked perfectly fine before this problem occured.
-------------------------
To my dismay, when I plugged the charger in and turned the laptop back on, I was greeted with a black screen, followed by the battery indicator light blinking white 3 times, in approx 5second intervals.
I thought it had been the battery not charging, but when I turned the laptop off, the battery indicator glowed orange, indicating that it was in fact charging like normal.
I've disconnected the battery by opening the laptop up, held the power button for 30 seconds, thinking the problem was static in the components, but that too did nothing.
I did notice a bit later however, that all the fans and internal components sounded like they were running.
Finally, I tried hooking the laptop up to an external display. As I suspected, it worked.
No signs of the original laptop display being detected, though. I was wondering if I could get the original laptop display working again.
I'd appreciate if anybody could diagnose the problem, and help me with a fix, if any. Cheers!

Hi,
Check the status of the display adapters in Device Manager to make sure that they're both OK.
With the laptop turned on try shining a flashlight at an angle close to the laptop's display and check any images on the screen. They will be very faint if they are there so trying in a darkened room may help to see them.
If you can see images then there's a backlight problem with the screen

Heya, thanks for commenting!
Nothing looked abnormal when I looked into both display adapters, all up to date, etc. Even checking into the Nvidia and Intel's control panels, both of them seemed to run normally, EXCEPT for the fact that the original laptop display is non-existent/not detected.
Doesn't seem like a backlight problem either, I couldn't make out a faint image of any sort.

Can you get into BIOS with a display?
Usually the Intel GPU is used for BIOS and then depending on the settings in the OS either the Intel or the Nvidia are used.

Nope, everything from the startup logo, post, etc. isn't visible.
Could you perhaps walk me through how I'd be able to access BIOS via the external display?

What is the status of the "Monitor" in Device manager? Hopefully it will show two, the external and the internal
You could try getting into BIOS via Windows
