=== compaq SLT-286 power supply ===

[Frederic BOSSU]

Hi,
 
I recently acquired an old Compaq SLT-286, but unfortunately, the power
supply was not given to me. So I had to find a way of making it work by
myself...
 
I tried to connect a + 12 Vdc to the power connectors that normally are
assigned to the battery. I put the ground on the most right pin, and a
+12V on the most left one. The two middle pins were left unconnected,
and of course, I removed the battery to avoid shortcuts.  ( Ooops...when
I say left/right, it's when the computer's screen is facing me, keyboard
is removed, and the battery connector is located on the top/left corner
:-)
 
Like this :
 
+------------------+
| ****             |
| ABCD             |
|                  |
|                  |
|                  |
|                  |
|                  |
+------------------+
 
A : +12V   D : GND   BC : left unconnected
 
With this, the computers boots normally on the floppy drive, but refuses
to boot on the Hard drive. I obtain a 162 error message, inviting me to
run SETUP. Then, I tried to run the compaq "setup.exe" diagnostic
program, and I managed to see that my hard drive is perfectly recognized
!
 
So, could anyone tell me il if I missed something ? Is my +12 Vdc
connexion enough for powering the whole computer ?
 
Actually I find very surprising that the battery's power connector has
four pins, and I managed to do it work with only two :-(
 
Thanks for your help, guys !
 
Sincerely,
 
Fred.
