Inaccurate "howto" tag

I just deleted it. There's a blurb in here about a single key combo.. that hardly qualifies as instruction. 174.44.47.3 (talk) 14:31, 17 December 2009 (UTC)[reply]

Is this article about Apple PMU's or a general descriptions of PMU's?

An article about Apple PMU's will be very different an article about PMU's in general. Right now, it seems to be an odd mix of the two.

The first sentence and title set the expectation that this will generally be about PMU's. It says, "The Power Management Unit (PMU) is a microcontroller that governs power functions of digital platforms". The phrase "digital platforms" is rather generic. However, a bit down this article starts talking about Apple stuff, which reads odd to someone who isn't thinking about Apple at all. The article history shows the first sentence was originally about the Apple PMU.

Not to be demanding, but if this is really about the Apple PMU, then I would expect:

- A separate article about PMU's in general
- A description of which Apple products have a PMU
- A general description of the Apple PMU's hardware
- Salient commonalities and differences between Apple products
- A description about PMU development over time
- A description of Apples PMU management software

If this is about PMU's in general, then dump the Apple junk... However, if I was the one who started the article, that would make me a bit sad :<...

What should a generic article about PMU's have? Right now, the article has a description of typical PMU functions. I suppose few examples of prominent PMU systems would be quite helpful (say, the Apple PMU). Beyond that, I'm not sure because PMU's aren't a standardized thing. Every product that has a so-called PMU will have unique power and business needs, and I imagine that the PMU systems vary greatly in implementation and features. Every electronic device ever created has *some* system for managing it's power (even if it's just a pair of wires). Does a power management system require a microprocessor to be called a PMU? There are many things that use state machines to manage power that may be termed a PMU. I'd say a PMU could be broadly defined as a modularized power management system that maintains state. If I haven't made a mistake, that definition would exclude things like LDO's because those don't typically maintain state. — Preceding unsigned comment added by 65.197.242.41 (talk) 16:08, 30 May 2019 (UTC)[reply]
