Compaq Presario 915us
A year+ ago my dog chewed up the power cord, I improvised by splicing
in a heavy duty 110; no big deal, except that the laptop would sometime
slightly shock the user (the cable was way to long when I spliced it
together). Plus the wife dropped it from an ironing board to a
hardwood floor when I first got it; only a crack in the case, no damage
to the machine (I did do a full scandisk), luckily the machine was
powered off at the time.
Fast Forward roughly a year:
The cdrom drive finally gave out (shouldn't have been making backup's
of my dvd's and music all night, I knew better). Now the real problem:
A few months ago the machine started locking up. The lockup is a
hardware lockup; for example, if you pickup the machine by the bottom
right corner it locks, even in the bios. So I started troubleshooting;
it locks whether on AC, battery or a combination of the two. It locks
with the hardrive & battery out or in. However, I noticed that it does
not lockup when I take the "Compaq Interface Board / Battery Board -
285525-001" out of the machine (if course by doing this I have to be
running on AC). Strange, but ok..so I ordered a replacement, I just
put it in and guess what, it locks with this one in as well.
Before it's said; I know I bought a Compaq, which in itself is strange
because I always recommended against them and I like to build my own
computers, but I got a crazy good deal on the unit from work (a Retail
(The manual is locate here:
I would REALLY appreciate any insight into this. Unfortunately I
don't have the money to keep trying parts (I'm missing working in the
computer shop already..for this project).

making the broken foil open more. When you remove it the crack closes and
the machine works
Get some cold spray / heat gun and see if you can thermally shock the board
/ solder joint to zoom in on the problem.
