My MacBook Pro battery is not charging for days. It only stops at 8% (not increase or decrease) when I plug in.
In addition, the light at the end of charger does not turn on.
What is the problem of it? How to fix it?

The lack of a charging indicator light is not a good sign, as it implies a hardware problem of some sort (i.e. cable, charger and/or MBP).
However, one thing you could do is reset the System Management Controller (SMC) to see if that resolves the issue.
If the problem still persists after doing this, an easy test to do is to see what happens if you use another charger/cable. If the problem still persists with another charger/cable, then you really should run Apple Diagnostics (you can also run diagnostics in the meantime if you haven't got access to another charger/cable).
Run Apple Diagnostics
Follow the steps below to run Apple Diagnostics:
Note: If pressing and holding the D key at Step 3 doesn't work, start again at Step 1 and, at Step 3 press and hold both the OptionD keys instead. This will try and run diagnostics from the internet instead, so you will need to allow more time for it to complete.
Regardless, take a note of what happens and let me know how you went.
I have been struggling with the same issue for a month. I tried everything to solve the problem including SMC reset, removing battery and etc. Finally, ten minutes ago, I sprayed both the charging connector and charging port with electrical contact cleaner spray and the problem was solved! Before try it be sure you turned off your MacBook Pro.
This appears to be a common issue with this kind of machine. Louis Rossmann describes how to address a motherboard repair on his videos like https://www.youtube.com/watch?v=5HUyEykicEQ .
my laptop had this same problem of not charging. I visited this page and followed the instructions to reset the SMC but that failed and ofcourse diagnostic is practically useless since it keeps asking you to "Connect the power adapter" which won't work because that's the problem in the first place.
I had to replace my charging port. That fixed my laptop. Hopefully this saves someone time and worring. It cost me N15,000 ($41.32).
I had similar issue, but the charging indicator was orange.
According to the system report, the health was normal. Tried resetting the SMC, didn't help.
I ran diagnostics after which the battery said
"Service Battery". I also drained the battery to 0% and then it started charging again.
Now it shows my max capacity is at about 40% of the design capacity (according to cocunut battery) so I will have to replace it eventually, but at least it's not a hardware issue (DC IN board or something on the motherboard).
