Does the battery in the laptop hold a charge otherwise? In other words: If the adapter isn't plugged in at all, does the laptop run normally?
Thing is, laptops work differently because you have a battery that sort of works like a large cap. If that battery isn't working, then ANY discrepancies in power from the adapter is going to affect the stability of the laptop.
I believe no, since I bought the laptop (used) with the battery not functioning at all.
Laptop will not power on without adapter.
Adapter does not charge that battery too.
However it has been that way for many years now (5 years) and just recently having this problem.
Before that the laptop performed very2 well without issues.
Reason for not removing the battery because it was part of the laptop's body (see pic, bottom left is the battery)

If removed, the laptop is not stable.
Any advice ? Appreciate your help and time
