I bought a vintage Compaq Portable 386 a few months back as a curiosity, and I've run into some problems. The machine was working fine for a couple of months but now refuses to power on.
I completely removed the power supply to see what the problem was. Since this is an old AT-class machine, the power switch is integrated into the power supply itself (e.g. it does not have to be connected to a motherboard to power up.)
When the power switch is thrown, there is a *click* from within the supply but that's it. The fan refuses to spin up.
The click noise is normal and is caused by an electro magnetic relay mounted on the supply.
I've opened the the case to check for any obvious problems (Blown capacitors, ect.; but everything looks good.)
If anyone has any ideas on what component might have failed, I'd love to know. Finding another power supply for this machine isn't really an option since they were custom manufactured to fit the portables case.
