My M2350 does not charge, does not power on, when plugged in does NOTHING, no light. From doing some research, it must be the motherboard's power "thingee" that went bad (I don't know what it's called). Question is; can I replace that power connector "thingee" on the motherboard, or would I have to get a whole new motherboard?

This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.
Make sure the ac adapter is correctly plugged into the notebook and into the power cord.
everything is plugged in correctly and it still will not power on,
follow these steps to complete a 'power reset' of the notebook.
Unplug the ac adapter. Keep ac adapter unplugged.
Remove the battery and keep the battery unplugged.
Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)

power indicator light should be lit on the ac adapter when it is plugged
Normally power on the notebook.
If the unit does not power on, remove the ac adapter and insert the battery into the system.
Plug the ac adapter back into the system, the battery charging indicator light will light up. If
the battery charging indicator light does not light up, the ac adapter

Are there any sounds like beeps with it? Most likely a hardware issue however, you need to contact support for troubleshooting as without having a one on one conversation it will be hard to rule things out
Test your monitor. To do this, you will need another monitor.
Plug in any desktop monitor to the output port on the back of the laptop. Restart the laptop.
If you are able to use the laptop using this other monitor, then your problem lies in a part called a video power inverter.
It is possible that it could be the lcd backlight, but that is doubtful.
The power inverter is available at many online markets for a relatively small cost. Installation is generally easy enough that any person with reasonable mechanical skills and a set of small screwdrivers can do it.
I once walked an 11 year old boy through the process from 1200 miles away over the telephone.
I have had this happen a couple of times but not sure if its the same for you. There is a small button on the upper right that engages whenever the laptop screen is closed. I was experiencing the same thing when I accidentally brushed the button. I didn't notice anything happen but, I next pressed the power button and it came on???? I guess there is some dohicky in there that triggers the off feature. I haven't decided to ignore this with software yet.
I saw this while researching charging issues where a new battery is installed, calibrated and now will not charge?? any ideas?
It's one of two issues. 1 - power supply. 2 - the power management chip on the motherboard. Since the power supply is the lesser of the two, try a new supply first. If that doesn't do the trick then it's the pm chip and the motherboard will need to be replaced.
*NOTE* The power management chip recognizes the type of power being used and allows the computer to switch between AC and battery power, it also allows the unit to charge the battery.
Try running you laptop with the battery and the AC adapter. If by plugging in your adapter there is no light indicator likewise or no powering up, then presumably there is a problem with the power supply circuitry in the motherboard. Normally the laptop should work with just the adapter, just the battery or both the battery and the adapter. If it will not perhaps your best bet is to seek professional repair service since this would require opening the motherboard. In most instances, this involves an smc fusible link, regulator transistors or even just cold solder or loose connections.
Hope this be of some help/idea. post back how things turned up or should you need further information.
Good luck and kind regards.
