I have recently acquired a non-working Compaq SLT 286 "Laptop".
The external PSU seems to work fine and is outputting 17.8V, but the internal power supply isn't supplying anything but the 17.8V at the output connecter.
I'm not a power supply expert but I've checked all the Caps and they all seem fine, but the middle transformer on the board seems to be broken, there is no connection between the two ends on the secondary coil, but there is on the other two so I think this is where the issue lies.
I can't find a replacement part for this so I am thinking the chances of resurrecting this PSU are slim. But I would still like to see if I can at least bring the device back to life.
Does anyone have the pinouts for the cable going between the internal PSU and the mainboard? Maybe then I could squeeze a different PSU in the unit (Has anyone ever done this?) I know I would lose the battery functionality but not sure if there are any other options.
Has anyone ever had this issue and managed to resurrect the device?
Matt.
