i think if this is right i dont know for sure but i had a zenith that
the hard drive died by not even powering up. seems a common thing with
zenith laptops. mine was also a 12v but no battery. i think that maybe
if u found a working replacement that might work but its a pain to get
into some of those zenith laptops.

I recently came across an early Zenith PC laptop, that
was not working and the price seemed right (free!). It's a model ZFL 181-92. My web
research came up empty as far as a service manual goes, and am wondering if anyone has any
leads/pointers to one.
Plugging in a 12 vdc adapter does nothing, however if I take out the battery pack
(it's a sanyo and the cells do add up to 12v!) and connect my power source there, it
comes alive. This leads me to think it's either a bad connection on the connector or
some bad components at the power input side. I should be able to figure that out when I
open it up, but the thing that has me puzzled is a 'hum' that is directly
proportional to the brightness control. Any ideas on what this could be?
The other problem it has is a "disk seek failure". I am assuming this is a
cleaning and lubrication issue with drive a:? Swapping drives is not an option since they
are not stock 3.5" drives...
Any ideas would be appreciated
