How to find HP hardware maintenance documents?

[Logan]

Hello.
Once I asked Hewlett-Packard support for a question about some specification of a product, and he gave me a link to the “hardware maintenance guide/manual”.
It a URL on official “hp.com”, the content is a PDF of the specific model, including a more detailed parameter than their webpage, difference among sub-models, and most interestingly, the procedure to disassemble the device, with CAD drawing of internal components.
I tried several times later, to ask their support for that, which always failed because they all act like people who have IQ<50. I also tried search engines with different keywords, all failed.
I lost the first URL, but I’m sure those are public documents. Can anyone help me to locate them?
Thanks.

HP test and measurement became Agilent, which in turn became Keysight. The HP brand name these days is computers, peripherals and services.

If you put your HP model number into search on the Keysight website, it should take you down a tree to the appropriate manual. I just tried it with the 1973 HP3310A and it found it without any trouble.

Thank you, but I do meant the computer part, which is still HP.

I think you are very unlikely to find such documents for PCs and peripherals, these are more commodity items that expensive test equipment. They are most likely treated as either no-serviceable, or FRU (module) replacement only. It might be different for server type products, but even then, they would work on a module or board replacement basis. If the documents don't appear on the website on the specific product page, then they are most likely internal use only.

I seem to recall HP switching to paid support for, ah, supported products. After a year, if you haven't coughed a sub you can't access owt, not even firmware updates.

Have you tried "HP service manuals" in Google?

I've struck lucky on a few, but not all times, on third party websites. HP computer service manuals are really quite good, with all of the mechanical and disassembly diagrams that your spludger needs. Give these guys a shot: https://www.manualslib.com/brand/hp/

50? That high? Customer "digital interaction executives" only get a self important career title because they know how to select a response from a dropdown. On their phone.
