Dead Compaq Armada 4210T Laptop

Hi,
My brother gave me his "dead" Compaq Armada 4210T laptop to repair.
I normally service TVs and other stuff. With fully charged battery,
absolutely nothing (no hard disk spin or floppy disk drive noise (with a boot
floppy), no "beeps" or lights) happens when you turn it on, but with the room
totally quite, if I put a floppy disk in the drive, I can hear a faint noise
when I turn on the power (but floppy drive doesn't run). If I remove the
floppy disk, it isn't there.

One other thing that happens, even when using the external power (plugged
into AC), 4 of five LEDs (power, caps lock, scroll lock, numb lock) light up
(the battery charging LED is off). You can't turn it "off" to make the LEDs
go off by pressing or holding down the power button. However, if I hold down
the Ctrl key, then press the power button, the LEDs go off and I hear a faint
"tick"

I opened the unit and found a tiny 5A fuse, but that tested good
(not open). I examined circuits for bad solder joints. Also checked for
loose connections of any kind.

If you ever had this experience, please tell me what you did to fix it.

Thanks in advance, Brad

What happens with no battery at all ? The battery can
end up so stuffed that it stops the system powering up.
