Presario 2140US power problem

My neighbor's Compaq Presario 2140US laptop suddenly will not boot up
or light the screen. With his HP 75W AC adapter connected to wall
110V, the laptop will not boot up. After many hours of charging, it
still will not boot up. Since I have read that this laptop has a
history of not working if plugged to the wall (???), I tried starting
up from the battery. Nada.

All the laptop will do is blink a front LED a few times - the surface
laptop start button will not light up.

So I am wondering - should I tell him to buy a new battery? I am
reluctant to tell him to buy a new battery (~$100!) if that is not the
problem. Might be the adapter? How can I tell which is bad, assuming
either or both are bad?

Thanks

Try checking the charger with a multimeter to see if you get a voltage
reading.
It could also be that the connector on the laptop is faulty so even if the
charger is OK neither the battery can charge or can there be power to the
computer itself, among other possibilites as well.

Well - I put my multi meter on it and read nothing - I set it on
mvolts as well as volts (DC). But then, I am not sure I handled the
multi meter probe ends correctly. I stuck one up the center of the
adapter end, the other I touched the side of same adapter end,

Did I do right?

Sounds correct to me. I would also reverse the probes and try reading again,
since you could be getting a negative reading that might look like nothing
is happening, depending if the inner or outer part of the connector is
positive or negative.
What I might suggest is to take the laptop + charger to a repair shop.
Any shop will have a universal charger and be able to hook it up to your
laptop to see if you can get it to boot if that is the problem.

They had a battery recall years ago on this and many other models.

Look here and have them go to the link and punch in the numbers from their
battery pack to see if they qualify. Its years old so they may not now.
