I can't tell if you got my previous response so I'll try again.
I pulled the battery and turned the laptop on but nothing happened other than the power and battery light blinked very faintly. I plugged the power cord in without the battery and tried to turn it on but again nothing happened. I did notice that while the power cord was plugged in without the battery the power and battery light blinked every couple of seconds. I thne put the battery back in with the power cord plugged in and I noticed the battery light doesn't come on...normally its green or yellow when its charging.

I would start by getting a wiring diagram of the starting system or a repair book. There is a 30amp fuse that powers the ignition switch and the starter relay in the fuse box. You should be able to jumper that relay and make the starter crank the engine. If so, check for power from the key switch to the relay and proceed with the rest of the circuits.
2 Suggestions:- 1) Did you tried to connect External Monitor? Tell me the status 2) Remove all Power Adapters and battery. Push the Power Button for 15seconds. Again Connected the battery and Power Adapter. Check if its working or not. If not then Must be Motherboard Problem.
Hello. The mo st common reasons for power issues are the battery, power jack and power adapter/cord. Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.
If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.
The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.
If no change, the power adapter is probably faulty and needs replacement.
If not an apparent hardware issue, since you replaced the RAM, then we'll turn to software.
Try System Restore. Boot your system to Safe Mode (press F8 repeatedly when powering on). Go to System Restore and choose a date when your system worked OK. Note: with System Restore, all your updates will roll back to that date. Follow the process.
Have you tried this with the battery removed, with just the power adapter? If it still just turns off than it could be a number of things. The CPU fan may have died, or the hard drive, either one of those issues can cause this problem.
This could be a bad memory chip or slot problem. remove the memory and try one chip at a time in each slot. If this doesn't work then the problem will most likely be in the power management system on the motherboard. This will require professional diagnosing in order to track down the exact problem component.
