How to fix battery not detected error on Windows 8.1?

Feb 13 I was using my laptop n put it on sleep at 7% because I was in a cafe and had forgotten to bring my charger. Got home and fell asleep, Feb 14 morning I turned laptop on without plugging it read battery 70%, as I was typing it died all of a sudden, then I remembered how the day before It was 7% not 70%, so I plugged it in, charge light won't turn on, so I press power, turned on but the charge light was blinking, then windows booted up, and it read no battery detected, unplugged and the laptop turns off.

Thought the battery died on me, so I ordered an original replacement battery online, Feb 16 it arrived, tried it on, same thing, no battery detected, tried shut down computer, unplug and power switch, turned on, still no battery detected,

used it for 2 hours or so and it turned off again, juice must've ran out, plugged in and it reacts the same as my original battery,

so I thought it's just a bad replacement battery so I went to the seller's place, tried 3 other batteries with the same result.

Still dunno how to fix, tried the reset bios setting, tried removing the small bios battery and discharge for method, tried driver uninstall method, tried a diff ssd method, same result. . .
