Computer Shuts Down Instead Of Sleeping Windows 10

So, I recently installed Windows 10 on my laptop ( HP ProBook 440 G2 ), but I've been facing some issues where, after a short period of usage (around 20 minutes and beyond) the OS simply shuts down when I close the lid or manually press the Suspend button, even tho I configured Windows to suspend when the lid is closed, when running on both AC and DC. The power and changing LEDs start blinking and it powers off, making me lose any unsaved work and taking years to boot up again.

Computer Shuts Down On Sleep

If I just started my laptop and haven't done much work, it suspends just fine.Here is a video of what happens:It keeps blinking like that for 50 - 60 seconds. Interestingly, also, when I press the button to shutdown windows, it also does the led blinking thing and takes longer than usual to power down.Things I've tried so far and didn't work:1) Completely low-level formatting the HDD and re-installing windows from the ISO from Microsofts website. Downloaded and installed all updates available.2) Manually updated every single driver on the laptop, there isn't a single driver requiring update.3) Tried to update the BIOS.4) Tried to re-flash the BIOS to the same ( latest ) version.5) Tried disabling Hybrid Shutdown.6) All Power-saving features are disabled within the BIOS.7) Tried running 'powercfg /energy', but returned only this single error.
