I have two HP minis: one is a HP2133 and the other is it's
near-identical relative the HP2140. They are a bit elderly but both
built like tanks with the same aluminium shell and a magnesium chassis
and with near-full-size keyboards they are a delight to use.

The 2133 is rather slow and sluggish but has excellent speakers and
high-definition screen built into the lid. The 2140 is more sprightly -
it will play full-screen video without any jumps or stutters - but the
sound is execrable and the screen is decidedly lo-fi.

I'm considering swapping the lids so the good sound and vision go with
the better processor etc. The fittings are identical in each: the lid,
hinges, microphone and webcam are all in exactly the same places but the
screen and the speakers are different. I know that the 2140 graphics
card will handle a higher resolution display because it automatically
adjusts when plugged into a higher quality external display. I can't see
what could possibly go wrong...

....But Sod's Law says there's something I've overlooked.

Before I commit myself to dismantling these machines, does anybody know
definitively that all the connectors inside will be the same and that it
will be a simple, straightforward swap? What are the gotchas?

Thanks!

Don't know about HP, but with Dell the same model of laptop, but using a
different screen (matte vs glossy, or standard resolution vs highDPI)
can have different connectors.

Good point. If nobody here has physically taken these models apart and
knows the answer first hand, might there be a repository of HP service
sheets somewhere to look it up. All I seem able to find are HP's
standard help pages and these items are no longer supported by them anyway.

Thanks,

Good point.

If the connector at the screen end is different, but the motherboard end
is the same, you could probably swap the looms

Also sometimes the inverter for the backlights are different in different
screens. Sometimes the inverter is actually in the screen itself, but if not
then a module on the pcb might need to be swapped.
Its been a long time since I saw inside aa laptop.

Another good point I hadn't considered. Might this affect the wiring
loom between the lid and the base? I had hoped it might be as simple as
unscrewing the hinges, unplugging the connectors and swapping them over.

Of course it may be. But I don't want to commit to dismantling either or
both until I am fairly sure of success.

Another thing worth considering is swapping the HD in the slower machine
for a SSD. Depending on what you use it for this might give you the
performance gains that you want.

I actually did that a couple of years ago and thanks to the lower
performing CPU and the general architecture it made very little
difference. The 2140 only came out a year or so after the 2133 but it is
a very much improved version.

Thanks for the suggestion.

If that doesn't help, repost on uk.comp.homebuilt; there are some more
