Question Charging suddenly stop when I try to use the device

[Saber_1]

It's my first time with a mac computer, I have a macbook pro 2011 .
The problem , charger works fine when the laptop is closed or idle, when I start using it like for example opening Finder, simply the charger lights turns off and stop charging.
Thanks in advance .

Just to be clear, you're referring to the MacBook not charging when you've moved the device a little or when you're just typing on the laptop the charging abruptly ends?

Might want to see which OS you're on and if you've got any firmware updates(though it's highly unlikely) pending.

A 2011 with original batt, it's worn out, needs new one.

But u say but-but-but..... no but mister, a worn battery gives out weird behavior.

Nobody disclose cycle count.

Nobody disclose cycle count.

BUT battery health is 95% .

not moving the device itself , I mean like typing or open applications or so .
