Five years ago, I acquired a nice used HP DV5 laptop. Only problem is
that after only running for a short time, it slows almost to the point
of a crawl in speed. At first I didn't know what the reason was, but
then I discovered that if I aimed a small fan at it, the problem went
away. So a couple of years back, I used it for days to help nuke some
hard drives that were being disposed of with no issues. Now I want to
bring it out for a long term data logging project. I suppose I could
put a fan on it again, but trying to cut back on electricity and also
there must be a better way. Any ideas would be welcome and appreciated.
Thanks in advance.

Have you checked the cpu fan for fluff etc ?

The HP laptops of that vintage are well known for their poorly
engineered cooling systems. Not only can the CPU overheat but the GPU
will also overheat. This will cause all sorts of video issues. Open the
laptop and thoroughly clean out the accumulated dust in the heat sinks,
vents and fans. There are all sorts of youtube videos to walk you
through the procedure. If you repair it before the video chip gets
cooked, it should last a long time. A bit of advice regarding the
youtube videos that demonstrate how to re-flow the solder on a failing
video processor, it's only a temporary fix and not worth the trouble.

Apple sold Macbook Pro's around 2010 made with a new soldering
profile/process that caused the GPU balls to crack. Eventually they were
persuaded (by a class action) to replace any that were returned, even
outside the warranty period - but the replacement logic boards had the
same fault and failed again within a year. Ask me how I know

After over a decade of using Apple hardware, I am now determined that my
next computer will *not* be an Apple.

There have been lots of similar cases with other manufacturers. It's not
only Apple users that have been affected.

Why? Apple IT is bought and paid for the software, productivity and
creativity in what ever is done with it. Metaphorically speaking it is a
smart vehicle for getting from A to B, and for many whole system does
the job well within its constraints.

If the system worked for you, then upgrade ...

The hardware is designed to be disposable, unserviceable and to be
eventually recycled to electronic compost. It has a limited lifetime.

If that irks (and it does to me, to be honest), then seems the value of
whatever is created is less than the cost of the equipment, and the
purchaser has made a poor investment that is heavily depreciating doing
very little.

Like a non-classic car.

Many reasons, all pointing to an increasing disrespect for their users.

Important core software (like Preview, Finder, etc) has fundamental bugs
over a decade old, while every release adds new things that mostly
aren't actually useful to anyone (remember why everyone hates
Microsoft?). But mostly, because they ditched 32-bit Intel mode, and I
have software I must use and cannot upgrade to a 64-bit version.

Also agreed. Various YouTube videos on HP dv5 fan cleaning:
https://www.youtube.com/results?search_query=hp+pavilion+dv5+fan+cleaning

What happens is the space between the heat pipe and the fan exhaust
grill gets clogged with cat, dog, carpet, blanket, etc fur or hair.
This is an HP Envy m6 that I repaired:

Note that I had to tear the machine apart completely in order to get
to fan exhaust area. This machine was not designed to be cleaned and
maintained.

This is a Dell Inspiron 1525 which had the same problem:
http://www.learnbydestroying.com/jeffl/pics/repair/Dell%20Inspiron%201525/index.html
What's different is that the heat pipe, radiator, fan, and exhaust
ports are all easily accessible through the bottom of the laptop.
