laptop turns off when charger is unplugged

Thank you veryyyyy much, that is exactly my problem from 3 years ago, when I gave my device to a repair shop to add a SSD, they broke one of these screws and used glue instead (!!!). therefore, its connection to the aluminum of the keyboard was disconnected, and I find it today :(

Hi, I don't suppose you could be more specific about those two screws, or provide a picture maybe? I am not getting any charging at all on an old Asus X550LA which I've just performed some surgery on - I'm trying to ascertain whether I've screwed something up or if the battery is just toast, or what. I'm running LinuxMint and system report is able to communicate with the battery, apparently, insofar as giving me the metadata as follows:

ID-1: BAT0 charge: 0 Wh (0.0%) condition: 34.4/38.5 Wh (89.3%) volts: 14.8 min: 14.8

model: ASUSTeK X550A26 serial: N/A status: Charging

But it's been pegged at 0% all along. I don't recall a specific cable connection that I would have disconnected between the motherboard and the battery charging port, so I can't imagine what has changed. I did have to re-solder the wires (3 blacks and 3 reds) to the power jack, they were broken off as a result of a drop apparently (I replaced the bottom cover as well). Just not sure what to look for here.

FYI, there is a Windows app that will give you a lot of info RE the battery

Run this in a CMD or powershell window. The window must be run as administrator

powercfg /batteryreport

It will tell you where the report was saved.

This is a hardware issue and these software solutions can't solve the problem.
