Listen, this is not actually urgent but I REALLY WANT MY **** LAPTOP BACK.

So, my original AC adapter died. After not charging and turning on the laptop for 10 days, i finally found a brand new AC adapter today.
And today again, i plugged the cable to my laptop ant it charged. I happily opened games to play. Then out of nowhere, my laptop warned me about battery being low. I checked the battery percent and what the , it was going DOWN. Even it was saying "plugged in". After 1 minute passed by, my laptop auto-turned off to prevent data loss due to critical low battery. I checked the charge led and it was showing blinking red light. Normally, it SHOULD've showed straight red light. The blinking means it wasn't charging. I really got confused and turned my laptop again. And when it powered on, the battery showed 0% percent. "This is it. Rip" i thought. Well... my laptop actually was working, but of course, at 0% percent. It was saying "Plugged in, 3 minutes into fully charged". So weird.

Instead of waiting, i searched up for solution. I was a bit mad, i'll admit. In the end, i found the same solutions...
Uninstalling the battery drivers.
...and i did uninstall it. Worst mistake of my life.
The solution said uninstalling the battery drivers are not dangerous because when the laptop gets restarted, it will auto-install the drivers again.
..at least thats what they said. I restarted my laptop and well..
This is why i am asking for your help.
It didn't turned on. It wasn't even charging, the led went dark too. So my laptop can't turn on and can't charge. It literally cannot detect any power.

Disable the battery they said. Plug the AC adapter and turn it on they said.
Yup, i did it it and my laptop didn't turned on without disabled battery and AC adapter power only.

You know, normally, all laptops work fine with no battery but with AC adapter cable.
My laptop can't even get power with that too...
So here i am. With a laptop not receiving any single power.

My thoughts;

I am stupid.
Anyways, the AC adapter is not charging the laptop. The battery is, well... i don't know?

The AC adapter was brand new and worked fine at first. It can't possible an adapter dying so quickly? It even was charging at %0 so..

The battery on the other hand, was a healthy 2.5 years old boi. I really don't think my battery got rekt. It's not old enough and wasn't damaged or anything. So why it's not receiving any power from AC adapter?

You know what forget the battery, the laptop SHOULD WORK WITH AC ADAPTER ALONE. No battery or dead battery it doesn't matter. My very old laptop was always at 0% due to dead battery and it was living with AC adapter. So how???
Maybe i were too impatient. I should have waited for battery to charge up, since it was decharging for 10 days.
Ofc, it is my fault. And i really need help.

Sorry, it's really long writing and i may have wasted your time but this situation is really, really weird that i must talk about every little thing.

Anyways, laptop with no power. What should i do?

Info:
-System: Windows 10
-Laptop: Lenovo idepad320
-i5 with 12 GB RAM, 1TB hard drive
-2.5 years old
-Healthy battery?

Things you should know:
-Any hardware damage is likely not possible. I really don't think the new adapter damaged my laptop. For example, both my old and new adapter is 65W, with same inputs/outputs etc. Literally they are like a clone.
-My battery was healthy enough, like i said. Maybe being discharged for 10 days damaged it somehow?? I remember it was being 40% percent for 10 days. With no battery drivers, it can't turn on. So it's not battery's fault i think.
-I can't open the BIOS either..there is no power. Nothing. Its almost like my laptop just died.

I know.. this really seems an impossible situation. AC adapter not giving any power now but was working several minutes ago. With a no-driver battery. No BIOS. No power. Nothing.
But maybe you do know something..?
Any help is accepted, no matter what.

I can't go to any pc repair for the next week. And honestly i don't want it. I wanna fix this mess myself. But of course, with your help.

what are the input volts and amps on the laptop? (there should be a sticker on the underside)
what are the output volts and amps on the new power supply?
what were the output volts and amps on the old power supply?

Thank you for replying.
Like i said, both old and new power supplies are sharing same output volts and amps:
New power supply: Output 20V/3.25A
Old power supply: Output 20V/3.25A
They are not exactly same, but the new one worked at first.
I am really unsure about if the problem is with AC adapter.
I am unable to determine the output and amps on my laptop, due to the sticker underside was damaged and ripped out several months ago. Considering it lived with my old power supply for 2 years, i think 20V/3.25A should work fine?
Here, i'll link my power supplies pictures for you to examine a bit more. Thank you for helping!

OK.... but what I am after is the figures on your laptop sticker for power.
I want to make sure the new power supply you got was the right one.
so if you can provide the requested info, we can determine if the power supply is/was to blame.

...okay i just got some critical info just now.
I assumed the battery is the problem and never really examined my adapter close. A minute ago, i examined my AC adapter carefully and... oh boy.
I think i got the wrong plug for the power supply. The plug literally says "250V, 10A"
YES. 10A. HOW DID I MISS THIS.
My adapter says "input max 1.8A, 240V". I dont really understand these things but i am assuming that the plug i just bought to my new adapter is horribly wrong, right?
The electrician just went and gave me 10A plug and i didnt even notice it. Even i said "for laptop adapter"
Anyways. I am waiting for you to confirm that my plug was really incorrect for my adapter. Or... plugging 10A to 1.8A adapter is not a problem?(if so, how.)
I am also a bit worried about my hardware. But i think the adapter just refused the electricity and thats why i am not getting power from AC? Or maybe my laptop just got fried.

If the amperage of an AC Adapter is grater than the amperage of the system you connect it, nothing bad will happen to the system or the AC Adapter.

Just remember : Power (in Watts) = Voltage (in Volts) x Current (in Amps )

I have seen at work Lenovo AC Adapters with the same power output but different plugs, so are you sure it makes contact with the power interface of your laptop?

I'm not sure we are on the same page.
the actual plug that goes into the wall is 10amps, all power points are 10amps. (here in Oz at least)
that plug is on a cord that goes into a 'black box' that converts mains power from AC to DC for the laptop to use.
it's this black box that I want the amps and volts from. it'll say something like input: 240v, 10a and output: 3.5v 1.95a
and there will be something similar underneath the laptop.

the adapter can be within about 10% tolerance of what the laptop excepts, anything much more and you run the risk of frying parts.

so, it's the output figures on the adpater and the input figures on the laptop that would help us here.

what did you replace, the whole power adapter or just the 3pin plug on the end?
