Compaq Contura 4/25c won't turn on.

Specs: DOS/Windows 3.1, 25mhz 486, 4mb Ram
Hi I've got a Compaq Contura 4/25c, it should all be working, although i no longer have the charger, I'v found a charger for the aero version, it has the same voltage and what not, but when we rigged it to the laptop, only the battery charging light came on(green) so i was wondering if there's any way of getting the correct charger plug, or knowing if the machine is dead. thanks for any help.

Does 'what not' include polarity--the +/- orientation? That's the first thing to check before you go plugging an unknown charger into anything. That's just a warning for future reference as you're probably OK since the LED came on but you should check it anyway.

Is the LED on the charger or the laptop? If the laptop isn't showing as charging then maybe the plug isn't making good contact.

Being such an old laptop 486SX I believe, I think the battery pack may be dead if the original. The original battery is a NiCad.

Its the light on the laptop, and thanks for the tip on the polarity :).
Basically, the charging light on the laptop comes on, but nothing else will work, we were also able to measure some power coming from the battery after it had been plugged in for a while, but still no luck with the laptop itself.

Usually you'd expect the laptop to run while the battery was charging but it's possible the charger isn't putting out enough current to do both, especially if the battery is bad and pulling too much current.

You probably don't want to put too much money into it but you might check ebay for another charger. If you can't get an exact replacement for that laptop then look for one with the correct voltage with the same or greater cuirrent output. And of course the right plug and polarity.
