Got the iFixit kit to replace the battery in my Mid-2015 Retina MBP, which was a workhorse. I did the full disassemble as their instructions recommended so I wouldn't get acetone on the motherboard; as many know, it's a real pain to unstick the glued-down battery cells.
Finally reassembled it, plugged it in, heard a small crackle, then smelled smoke. Also, the caps lock key was lit up for some reason.
I have no idea what I did wrong - I put all the parts back in the same way they came out, there were no screws left over, but getting the MB back in did require a bit of effort as the first time, the screw holes didn't line up, so maybe I flexed something or shorted a ribbon cable.
Going to take it to MicroCenter tomorrow to see if there's anything salvageable in it. Thankfully I had already removed the SSD and put it in an external enclosure so there's no data loss, and the SSD I had put in it was blank with a new OS install - it'd be nice if that wasn't fried, at least. I've got newer M1 and M2 Macs now so it's not a huge deal for work, but it's a bummer.
I had taken the MBP to the Apple store before to look at the battery, which said it needed service - it was only holding about an hour's charge - but they basically waved me away saying to come back later.
I really should have had a pro do this, in retrospect; at least if I get a future M2 laptop the batteries on those are much easier to replace.
