Sorry for the lack of updates, I'm still waiting for the verdict from the repair shop. Turns out the laptop battery is more or less fine - the issue is in some fine electronics burning themselves up, so the two options were to either let the laptop fry itself from the inside until it inevitably dies or perform some risky operation that might either salvage it or kill it completely. Chose the latter, but I'm yet to hear a word back on how it's going. I really hope they save it... So nervous😥
TLDR: I still don't have any PC to do my work on and might need to buy a new one soon (hopefully not).
I'll be going to my parents' place soon, so perhaps I can use one of their laptops to at least draw some illustrations. I apologise for all the holdups, this whole situation has been really troublesome.
