Samsung Note 10.1 (2014) requires USB plugged in to stay powered on

I have a SM-P600 device.
Had the device drain battery and not power on at all.
Replaced the battery and was then able to plug it in and see it charge.
Once fully charged I powered on the device and all worked fine.
But when I in plug (with 100% Battery) it will go to black screen and power down.
Tested it several times same result. Unit must be plugged in to work?

Anyone have suggestions? Unfortunately it's out of warranty?

Reboot requires registration on network.

That's my problem. Everytime I have to reboot, my phone forgets my network and I have to register on it. I'm on CM12.1 nightlies.

Samsung Kies requires update to USB driver (Note 3) and crashes Windows 10

Hi there,
I'm having this problem when I try and update my OS on my Note 3 SM-N900W using Samsung Kies version 3.2.15072_2 on my Windows 10 Machine. Each time is the same - Kies connects fine to the Note 3, and notices there is an update - do I want it - OF COURSE!!! So I select that, and then Kies informs me it needs to update the USB driver before it proceeds - please unplug the phone. Then a message this could take a while. After about 1 minute I get the BSOD and windows apologizes but it received an error - attached - and must restart. EVERY TIME!







Tried manually installing the Samsung USB driver but Kies doesn't care - wants to do it for me. Yes, I granted Kies permission to make changes to the computer.

This also is happening with my Samsung Galaxy TabS 8.4 - since the issue is the same I have only started one thread. I've spent hours searching online - driving me crazy!

Suggestions?
Thanks!
