Device will not fully power on

Tekst:

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!
