PC powers down without secondary monitor
To start: I know this makes no sense.
I have an hp dv5215us that I have been running off a power cable with no battery for quite some time now, hooked up to a secondary display, a Dell E151FPp. Every now and then I will unhook the secondary display and take the laptop with me to work without issues. Last night I popped my Win 7 install disk while running XP to install, clicked what I needed to, and let the install disk run. Now that Win 7 is installed, I am running into the following two issues:
1) When the secondary monitor is unplugged, the computer will not power on, let alone boot. No blue lights, nothing.
2) When the computer is on and I unplug the secondary display (I learned the hard way), the laptop powers off instantly, as if I unplugged it from the power source.
I looked in device manager under monitors and it only shows one. I am getting mirror screens now, and under the display options, the resolution options available to me look like those for the secondary monitor, not for the laptop monitor. I installed Windows 7 with the secondary plugged in.
I bought a new battery for the laptop online last night. I know it sounds like a hardware issue rather than an OS issue, but the laptop and secondary display didn't move anywhere since it was running without issues in XP, so unless there was some kind of short or something while the installation was taking place, I can't think of why this would be happening.
