My coworker has a laptop that only works when he jiggles the power cord so it's plugged in just right. Can anyone recommend a power supply for a laptop? Is it even feasible to change out the power supply in a laptop?

This may be a silly question but wouldn't the brick in the cord to the laptop be the power supply?

I believe you're referring to the transformer (Maybe? Not too sure haha!)

Technically regardless of desktop or laptop the "brick" is so heavy because it's a transformer. The name used in its place is power supply unit; the unit supplies power to the system after being converted from a wall socket. It doesn't create power and supply it.

If he needs to jiggle the power cable to get it to work, then the problem is most likely with a loose power connector on the laptop. Unfortunately, there's no fix for that except to replace the motherboard.

That answers my question. Thanks!

Yes, the brick outside of the laptop is the power supply. Chances are the problem is with the plug inside the laptop, though, not the power supply or the cable between the power supply and the laptop.

Yeah I have the same exact issue with my laptop. The only way to fix it is to fix the socket somehow. I just learn to live with it.

Sometimes you can replace just the socket and not the whole motherboard. You'd have to do some soldering though.
