Okay the logistics here of this laptop that would be normal for the power light not to come on without battery in place REASON? Because this laptops primary source is battery secounary source AC power.
A Blinking light and no boot means a hardware failure. I would need to personally look at it to tell you 100 percent what is the cause but I would rather you take it to Best Buy and have them do a full eval on it for under $50 bucks if there is something really wroung they can follow up with a warranty claim.

I had the EXACT same issue on my HP Pavilion DV8000. After reading this thread I started disecting the machine, sure the issue was a faulty internal power plug/cable. It is TRULY a big job, but very doable without special tools. You pretty much have to take every single screw out of the thing to get to that stupid cable.
Here are a few things to know:
1) there are a lot of screws - mainly long black (L 12) and short silver (L 5x2.5). Keep track of all of them in order so you don't end up like me - with 3 leftovers. Lol. There is ONE long black screw that is a little shorted than the others (L 10). This is one I had left over. There are two VERY tiny black ones. I also have one of those left over. There is also a few smaller black ones, too. Just keep them all noted as you remove them and remember where these odd ones go!
2) There are some very flat band cables that plug in to tiny plgs. However thereis no plug on the cable. The flat end just shuves into the plugs. These are very delicate. be gentle with them.
3) When you finally get the housing for the fan loose you can now get to the entire power supply cable. Here is a note: I FIXED my problem by unplugging this cable and plugging it back in. The cable runs under the fan housing, and it seems like you have to remove that housing to get to the cable, but actually it comes out again right next to the processor and heat sink. There is a thin sheet of black sticky insulator tape over the processor and the cable at that point. You'll have to gently remove it. There is not much room there, but you CAN unplug the cable without removing the entire fan housing.
Here is what I did to test this plug and cable. After unplugging it, I shoved a tiny straightened staple (the female plug is very tiny) into the female receptacles for the prongs on the motherboard (red and black only). Then I plugged the power supply in to the power jack. With a DC meter I verified that the female end of the power cable inside the machine was getting juice, and it was.
With nothing left to test, I put it all back together (save three screws) and it is now charging the battery and running from the ad power plug. Whatever I did fixed it!
One last note: There are 4 sequenced screws that hold the heat sink tight. These are under a bit of pressure so the sink is tight. DO NOT remove these as the sink has a heat conducting "goo" that helps it disperse the processor heat. As old as these machines are now, you don't really want to disrupt that "goo" and risk the processor over heating.
I hope all of this typing helps someone.

try pulling the hard drive loose and see if it tries to boot and comes up with no boot device found if it does the hard drive is bad if not the bios is corrupted and will need the bios reflashed.

Sounds light a power switch short, but lets try to take the memory out of the laptop and power on the laptop. Does it boot up? if so lets try 1 memory stick at a time.

Battery is part of the power/charging circuit. As you have found it needs to be in place; kaput or not.
Believe your problem to be Power MOSFET's.
