I've got an older Norelco electric shaver, which has some kind of
'fast charge' ni-cads in it (haven't looked, but that's pretty much
what they had when it was made).  Normally, it will recharge in about

I'm attempting to locate a problem on my Dell D1025TM UltraScan
(Trinitron) monitor.  I posted about it a week and a half ago.  I got
the D board out and am checking for bad solder joints.
I'm not sure if these should be re-soldered or not.  If so, what's the

I bought a new Ferguson FTV210N 21" television and it

specific details and pictures after I get it later today.

I am looking for info on efficient management of a service department doing

Would appreciate any pointers to this info either books or online.
