Don't really want to spend 200 euro to repair something that cost me 800

Right off the bat : electronics repair is not my job, this is my first time poking about on a motherboard with a multimeter, and I'm unsure I'm measuring right. I have an Acer SF314-42 laptop whose battery won't charge, in windows (able to boot fine with power cable plugged) it says it's charging and battery at 0%. If I unplug the adapter (charge via USB-C), the laptop instantly turns off.

I've been able to find a schematic here which I've opened the laptop and checked the connector between the motherboard and the battery because I found a tutorial for an Acer laptop having the similar issue here though it's not the same model, it looks like a similar adapter. The guy in the video measures the voltage between every pin of the laptop and I tried to follow a similar diagnostic procedure.

I did that, and in the schematics linked above (which I've been able to view online with nextbv I see that the battery motherboard connector is called PJP2 and the pin all the way to the right is supposed to be 12.6 Volts, which I imagine is to be measured w.r.t. the ground. I suppose that if the motherboard works fine, I should be able to get 12.6 V reading when reading the tension between that pin and ground when the laptop is plugged in ?

In any case I tried to measure that and was getting the following (rather worrying) measurements, see the attached pictures and captions on google drive here.

What can I conclude from this ? Is the board toast and should I replace it ? Or is it the battery ?

Thanks !

The dc port stopped working some time ago so I continued to use and charge it via the usc charging function.

Recently the laptop has stopped taking a charge entirely.

I did try to have the dc port fixed a while ago but the person said it wasn't fixable.

Anyone know how to get this laptop up and running again? New battery? Or whst?

So I have an Acer Swift 3 51 56MY gold laptop. The original charger unfortunately broke, so I had to buy another one.

Initially I bought a charger from Amazon that said the charger connector size was 3.0 x 1.1mm. However, this did not fit into the laptop's charge port, so I had to return it. I found another charger that was 3.0 x 1.0mm. This one fit into the laptop. The problem is it's very loose and comes out of the port easily which results in continuous charger disconnects/reconnects.

As a temporary "fix", I carefully added some solder to the charger connector (on the metal part) and now the charger fits into the laptop port and doesn't easily fall out. Laptop charges and no longer disconnects/reconnects every time you move the laptop around. It also comes out of the port without issue (just have to use more force now since it now fits tighter into the port).

I'm not particularly happy with this workaround since I'm not sure if it's safe to do this or if the workaround will last, so I'm still on the lookout for a proper replacement charger. Does anyone know where to buy a charger that properly fits the laptop? I'm located in the UK.

Appreciate any help.
