The problem I had with my laptop was I decided to do a deep clean and repaste and tried to follow a dismantling instruction for my model laptop it stated there was a screw I had to remove so I could lift the keyboard could I bugger find that screw anywhere eventually I found on some very obscure site that some may have the keyboards glued instead of a screw oh the fun I had removing the keyboard it eventually resulted in the keys flying everywhere once the glue let go of the board no matter how careful I was 🤣 luckly I took pictures first cuz I instinctively expected the chaos. Laptop still going strong after 16 years and doesn’t sound like a jet engine anymore

The more access panels the better, for sure. I also like it when they use as few different screw sizes as possible. And also don't have some flex cable positioned to be ripped apart when you try to peel the bottom off or whatever.

I think the most disturbing disassembly for me was a Surface Book. It was already destroyed but it's held together with adhesives. I wanted the 512GB M.2 drive out of it. Peeling that thing apart was...Interesting.

I have recently had a laptop that wouldn't turn on.
The solution was trivial - just disconnect the battery for a moment.

Implementing that procedure, however, was a nightmare - accessing the battery requires total opening!
First, the easy part - unscrew a bunch of screws.
Second - find additional screws hidden under adhesive feet.
Third - painful struggle to undo some latches, completely inaccesible, and prone to breaking!

Yes, I hate single-use products with the passion of a thousand dying suns!

Workstation-class laptops are usually more difficult to open. My ThinkPad P53 has an access panel on the bottom, but it only allows access to the battery (screwed in, not glued), drives, and half of the RAM slots. Everything else (including cleaning the fans) must be done from the top, which requires a special tool to remove the keyboard. The first two RAM slots (out of four) are the ones under the keyboard.

At least it isn't Dell with their "we swear we'll make it a standard" proprietary RAM modules that were only used on the 7x70 and 7x80 series and then abandoned. As far as I know, you can't retrofit standard CAMM into those laptops (especially since the only modules I've seen were LPDDR5X instead of DDR5). I would say that it doesn't matter because those laptops are a complete pile of shit (constant 2-second hangs, WHEA_UNCORRECTABLE_ERROR BSODs, an undersized cooling system with the exhaust half blocked by the right hinge, and a single-button clickpad instead of a proper 3-button touchpad), but where are you going to get a new laptop with 128GB of RAM today?

Phones being glued together really sucks, and you can't get batteries anyway. The original manufacturer won't sell them (at least not at a fair price), and everyone else sells used batteries with a new label. When the battery dies, you just have to replace the entire phone, which is really stupid, expensive, and wasteful. Then all hardware made since 2022 draws more power, so the battery life is worse and results in more charge cycles over the same period of time (usually two years before you're eligible or a replacement). In 1-2 years, low-end phones will have vapor chamber cooling like iPhone Pros simply out of necessity, not to copy Apple.
