What computer do you have?

[Aractus]

You said "User-serviceable means that you can replace the most common bits that wear out - in a laptop that's means the battery is the most important."

I linked to a website giving detailed instructions on how to replace the battery. That alone disproved your point.

No it doesn't, you need to be able to buy the replacement part you're replacing.

I linked to Amazon where people are selling batteries for MacBooks. That again, disproved your new point about not being able to buy batteries.

And with no evidence that they're even genuine new batteries. Which I doubt, because like I said Apple's policy is to cease business with any manufacturer they find out has been selling them to third parties.

So now, let's settle this once and for all shall we?

Boom. What's your next objection? Probably something even more ridiculous.

I wouldn't trust that company if they said the sky was blue. Firstly, their genuine batteries are labelled as "refurbished". Secondly their supposedly new batteries from supposed company "NewerTech" do not have a C-Tick. Seriously? On the actual NewerTech website there is no indication anywhere that they have been issued an electronics certification from any country - the US, the EU. A genuine electronics company would have the certification displayed so it can be verified by users. Or how about this iphone5 battery supposedly new with a 2012 manufacture date? Like I said I wouldn't trust them.

Bullshit they do. Pretty much the only standard these days is they have a touchpad and a keyboard. There are laptops out there with detachable screens, with touchscreens, with or without CD trays, etc.

Look, the point is, you shouldn't just assume some feature that exists on another laptop, or even most laptops, exists on some other laptop. That's why you list the specs alongside the laptop you are selling.

Monitor, USB, power cable, hard drive, display adapter, ...
