Took my Compaq Armada Laptop apart... Wont start up

I have an old Compaq Armada m700. I took it apart to check out a possible fan issue, and after I reassembled the laptop, it turns on and counts to about 540000KB (Total memory) and then does nothing. It does this at the Compaq splash screen. I think I may have disconnected the battery to the bios and now the thing is dead.

Can anyone help me out, Is this thing dead or can I reset it? I read a repair manual to no avail, nothing about this type of issue.

 

You took it apart... and now it won't start. And you want help from us?

I'm not trying to sound like a jerk, but anything could ave gone wrong there.

 

you probably didn't connect something back correctly

 

You would think that, but I did follow a manual, and everything is plugged back in. I think I reset the BIOS something to that effect, and I need to know how to reset it. Like moving the jumper on a desk top mother board. I am trying a procedure that I read somewhere else which involves pulling the main batt, the cmos batt, and letting it sit for five minutes.

As far as connections, I went back through it, all wires are plugged back in, they are slotted to avoid misplacement, all screws were marked as they were removed, and they all went back in, as to avoid a bad ground or something, and further, I get the Compaq Splash screen, it counts the RAM correctly, then quickly states a "162 system option not set", which HP says has to do with the BIOS not being reset properly. Hopefully the power loss will correct this, but if anyone has any other thoughs, I would love to hear it.

 

To reset the Bios the only thing you have to do is remove the little battery on the motherboard, and as you said let it sit for 5+ min and then put it back again.

 

I replaced the battery, and found out the laptop works fine if I have it hooked to an external monitor. The Compaq splash screen comes up on the laptops LCD, then you have to use an outboard in order to see anything including the BIOS. Once in windows, the video card utility does not recognize the internal monitor. I dont know what to think of this, since it will work for the splash screen but not the rest of the time. The BIOS has a setting for primary or secondary monitor, but according to the manual, it is for a docked laptop, not a standalone... I will try some more things tomorrow, I am happy that I did not fry the thing!
