Does the old Adamo 13 require a "sensing" power supply?

I've been trying to revive a nice old Adamo 13, which WAS a premium model (even can take an internal SIM card!).

I've fixed the touchpad, and have just gotten a new battery "slice", but, like the old slice, the machine does not "recognize" it.

Now my original sleek Dell power suppy had died, so I'm using a more generic one that fits fine, and puts out 19V @ 4 amps, which should be fine, but now I'm wondering whether the original adapter might have incorporated technology that worked in conjunction with some kind of Dell battery sensing mechanism.  Does anybody know whether that's the case?

This other adapter certainly runs the laptop just fine, apart from not being able to battery charge.

I DID manage to upgrade to the "latest" BIOS version, but it didn't help.

Thanks much!
