Caretaker's right. Those Bic cap make an excellent spudger substitute. I also used discarded ice-lolly sticks, wooden or plastic. Cut or filed down to a blunt chisel-like end, helps to provide a little leverage, especially for some of the very fragile cable connectors that can be encountered. HERE's a very useful guide for recognizing and disconnecting some of the widely used internal cable connectors. (I wish I'd found that link when I started out refurbishing, would have prevented a few problems).
What model of HP Pavillion is yours? There are dozens.

I personally don't wear an anti-static strap when working on pc's, but do frequently touch any metalic surface to discharge any body static.
Regarding cleaning the keyboard after removal. Start by using a can of compressed air to gently blow and dislodge the dust.
Then with lint-free cloths and/or Q-tips use a 70% Isopropyl alcohol solution, which can generally be used everywhere, although keep it away from non-glass LCD screens. I also use Isopropyl alcohol swabs that can be found on Amazon. Keep cleaning liquids clear of internal components as they can cause electrical shorts and static, harmful to the system.

Very thin, curved so no pointy bits and you can hold the blade without fear of cutting anything you shouldn't, including a finger. You wouldn't want to add blood.

Apologies folk, but this is now definitely moved to the back burner. I was going to say a rainy day, but that would be just plain silly.

Having looked in both tool boxes last evening for a spudger substitute, I came back to see Tweedpipe's question on the model number. I'd already dropped the battery, but that's all, so this morning I put it back in, reconnected the power and... nothing, it won't boot. As mentioned it was a second backup, wasn't holding anything critical, so I'm really not too bothered at this point.

Thanks for the pointers and hints.

I frequently pick up cheap functioning laptops at thrift stores for a handful of dollars, strip 'em out completely just for the interest, and rebuild with the assistance of the aforementioned site. I know my limits though, which generally doesn't run to logic board repairs.
Give me a shout if any guidance required. I frequently share repair advise on an AppleMac forum, especially for any desktop or laptop computers that most repair specialist have never heard of or don't want to know about.
This is a relatively new hobby for me, and over the last 3 years I've refurbished most Mac laptops between 1991 and 2013, retain an example of most, and love 'em all. Having said that, the 12" 2003-2006 alluminium G4 PowerBook still unnerves me whenever I have one to disembowel and refurbish. Most definitely a "Don't try this at home" - unless one wants a real challenge!
A few (?) years back I replaced the screen ribbon cable on my Acorn A4 laptop - couldn't believe the number of components packed into such a tiny space! It took four hours, much coffee and almost a visit to the shrink but I finished it with only a handful of micro-screws and small bits of metal left in the saucer.

It WORKED!

Then I tried to close the lid - and found I'd put the cable the wrong side of the hinge so it wouldn't. Another four hours and even more screws left over and it worked - and closed.

Never again.....

Had to check on a picture of the Acorn A4, knew the name but couldn't place it. You're right, it appears very compact.
Now try a similar refurb on a 12" 2003-2006 G4 PowerBook. You'll probably need a straight-jacket on completion. If one gets a cd/dvd well and truly stuck in the optical drive, there's only one way to retify. Complete dissassembly of the laptop, as the optical drive (first in, last out) is located beneath the logic board. A not-so-cool 50+ action steps just to remove, and same to reinstall. Sheer Apple madness, designed during a nightmare!

It was certainly primitive by standards of today, at least in mechanical construction, but ran 32 bit RISCOS which was way ahead of the time. IIRC the B & W screen was actually split into two although you'd never know it. I spent many long nights programming with it when away from home, transferring the programs onto my Archimedes. Those were the days....
