Device will not fully power on
Hey guys, so I've reviewed the forums for a few hours and tried quite a few things to get this laptop to go on.
Basically, it came in for a no power issue, no matter what you did it didn't power on.
At first I thought it may be a battery, so I replaced it to no avail. I then read online that if I hold the power button for 10 seconds and the plug the device in and continue holding the power it would power on, and it did. Now it would go to about two thirds of the loading bar, I would press the power button and it would boot to the login screen but only last about 2 minutes after you logged in.
I then reset the PRAM, no success, then I reset the SMC, no success, then I removed one RAM stick at a time, no success.
Also, I forgot to mention that the fans are running at full speed as soon as the device tries to boot, I tried to clean any dust out, but there wasn't much there to begin with.
Now I have it in front of me, it boots, fans full speed, sometimes to two thirds of the bar, sometimes to the login screen and about 30 seconds after logging in to a user it automatically powers off and automatically reboots and repeats over and over again, even if the lid is closed. If I unplug it from a power source, though, it stops trying to boot.
I've also noticed that there is an X over the battery symbol no matter what battery I have in the device.
Let me know if you can think of any solutions!

What happens when you press the on board battery checker? How many LED's two you see? Also when you plug in the MagSafe cable what color is it - Amber or Green?

The light is green when I plug it in. The battery checker flashes full 5 times and then off if it's plugged in but doesn't do anything when it's unplugged.
Also, I'm not 100% it's a 2010, but it's anywhere from 2010 to 2012.

Lets try this open your system following the first six steps from this guide: MacBook Pro 15" Unibody Mid 2010 Logic Board Replacement then jump down to Step20 and carefully disconnect the battery checker. put some tape across the cable so it doesn't short. Reconnect the battery see if thats better.
