I have a five year old Compaq Presario M2000 laptop that will not
charge or run on ac power anymore.  It still powers up fine on battery
power, but once the battery runs out, it'll be over...
I have had issues in the past with the power connector on this laptop,
but was always able to fix the problem by resoldering the connector to
the board.  This time, no luck.  I'm wondering if the power adapter
may now be bad.  But I hate to spend $40+ on a new power adapter (or
more for a universal adapter) without knowing for sure that is the
problem.  Is there a way to test the power adapter?  If I knew someone
with a compatable adapter, I'd just borrow it and see if the laptop
works on ac power with a known good power adapter.  Any ideas?

Less than $10 on eBay.  I'd take a chance.  See:

I too was going to mention the eBay option. That many times you can find 
them for about 10 bucks. The only bad part is some of them are not UL 
approved or anything. This one looks like it is covered though.

The ones that hasn't passed those standards tend to have higher ratio of 
radio interference problems. Some also worry that they maybe a fire 
hazard as well. Although I believe such an event would be pretty rare. 
And if it freaks you out, just don't leave it plugged in when you are 
not around. But this one that J has posted looks okay, so not too worry.

I recently had the same symptoms from my daughters HP laptop. I tested the 
power adapter with a voltmeter just to see if there was any output, which 
there wasn't.
