Lenovo G550 Hardware Issues?

[FlamingBurrito15]

Hello I have a Lenovo G550 and I have some issues assumably with the hardware. The issues are:
1. Now and then my computer would randomly shutoff. Like instantly closing your eyes.

2. Also my computer is slow/lags like crazy to the point where it is semi unusable.

3. I can't really charge it, I have to wiggle the part that connects in the computer.

Any suggestions on how to fix these issues?

Battery is most likely shot or charging circuit is bad along with a bad charging port. If its an older laptop, just buy a new one.

I believe it might be the battery because I hear an electricity sound when it shuts off most times... Would I be able to run the laptop without the battery?

Yeah you can but if you have to wiggle the charging port to get it to work at times then that definitely needs replaced too.

Well I did something that fixed it... I clean reinstalled windows and it helped... I also shook my battery not sure if it did anything though...

Shaking batteries usually doesn't fix anything on its own.
