My Asus laptop is around 3.5 years old, and I have been using Ubuntu extensively until the hard drive got corrupted (bad sectors started increasing). You can refer Ubuntu 20.04 going into Read-only filesystem where I asked a related question.
I have been using Windows ever since, and everything was fine. Windows is mounted on SSD, and the issue of the bad sector did not affect Windows. But I recently started using Ubuntu again, without replacing the disk. I had forgotten about the bad sectors problem. There was a new problem waiting. It was that the battery always shows 0% while charging (this had not happened when I was using Windows), and shuts down when I switch off charging. This problem is happening in Windows as well, the charge is stuck at 0% while charging and shuts down when removed from charging.
The output from acpi -i shows that the last-full-capacity is negative. I think this is a software problem (maybe some corrupted data from the hard disk's bad sectors updated the BIOS info), and not a hardware problem, though I might be wrong. This output is as follows:
Battery 0: Charging, 0%, charging at zero rate - will never fully charge.
Battery 0: design capacity 3649 mAh, last full capacity -36 mAh = -1%
The output from upower -i /org/freedesktop/UPower/devices/battery_BAT0 gives the following output:

Is this actually my battery dying, or is it just some software/BIOS issue that could be corrected without buying a new battery? And if it is just a software issue, could you please guide me on how to solve the issue? I am presently a student who will be graduating this May. I plan to use my laptop primarily for coursework and running some NLP models for my projects. I don't plan to buy a new laptop before May, and might buy a new laptop later, since I believe replacing both HDD and battery in this laptop could actually be very expensive and a new laptop would be much better.
