- Excessive constant CPU strain (I'm not talking about decoding or gaming, I'm talking about 24/7 excessive use)
This is the manufacturers fault for putting in terrible heatsinks. My Macbook's CPU ran at 65 degrees celsius idle after 20 minutes right out of the box. Google reveals that this is standard on all laptops. They should add a lap warmer feature to their tacky little sales pages lol.
I am unable to comment on this as I do not have a developed understanding of your computers heatsink or the standard for 'most' laptops. However regardless, that has little to do with strain on your CPU-- if you are too intensive with it, whatever heatsink, you can lessen its life expectancy and ultimately its performance.
- Poor ventilation and overheating
See reponse #1.
This has nothing to do with the hardware itself. I am referring to YOUR handling, if you block fans or place it in a hot room it is YOUR fault.
- Bad power settings (constantly having the computer on, rarely shutting it down)
Never messed with power settings and I always shut my computers down when I'm done with them. Even if I didn't know, I know for a fact that Apple computers do not generate almost any heat while in sleep mode.
To simply address the last part, again you are missing the point. It is not about the heat here, it is about the usage of hardware. Office computers are known to last lesser than a general home computer due to the time in which they operate, sometimes overnight 24/7.
- Poor handling (how rough you are with the device itself)
Never dropped it/smacked it on a wall while waiting for video to export
I'm curious as to why you keep assuming you need to be doing it while the video is exporting to see the slowness. This is
not specific to what task you are doing. Damage is permanent, it will effect what you do long afterwards. Your wording does make me wonder if you have done this while not exporting however. Do note I was strictly referring to throwing the computer on your bed, being rough as you place it, carrying it in a bag and throw the bag, and other harsh behavior. While computers can take a bit of rough handling, it is best to be careful.
- Dust build up, crumbs in the keyboard, dirty handling
Doesn't affect the parts unless it gets stuck in the fans. I've cleaned the fans multiple times. Doesn't help.
Dust can effect performance or cause additional risk if its on any electronic hardware, I believe. I can't confirm that but the fan alone is not the only priority for this note.
Then why are you listing answers that you know are for the most part completely irrelevant to what I asked you?
This is very relevant. I'm waiting for it to click or for you to stop being so bigoted. I can quite confidently say you are being a typical moany Microsoft supporter rather than someone who has both ends of the stick.
