Macbook magnet

hey guys,

you know how the macbook hold it screen together with magnet right?

i just realised that the macbook lid magnet is located at the top lid. there is two of them (where there is a line bulge), i use stainless steel teaspoon to check it out.

now the problem with that placement... is that the harddrive is directly below the magnet when the lid is closed. isn't a harddrive is really sensitive to magnets?

care to give an input (comment)?

and dont tell me that " oh, i'm sure apple has already thinks about it when designing it" cause during the rush of the designing phase of todays consumer product, things sometimes may get forgotten.

 

I think you need a pretty strong magnet to damage the HDD. The magnetic field on those holding the screen in place are just too weak

 

have you try holding a steel spoon next to it? it pull them so strongly! the magnet is pretty strong... though i dont know how strong of a magnetic force is needed to effect a hardrive.

oh nice sig and avatar

 

I've never had any issues.

 

Well, if you were to place those magnets directly on the hard drive while it was spinning at full rpm, you may have a slight problem. The that the magnets attract to, however, acts as a shield for the hard drive so no worries!

 

I'm pretty sure that you would notice instant, catastrophic problems if a magnet was interfering with your hard drive - and I would also SINCERELY hope that the Apple designers made sure that the magnets they used were weak enough to not cause problems with your spinning hard drive.

 

Perhaps other companies (Dell) work like that, but if you actually knew anything about the Apple design process, you'd know that they put more time into designing their products than most other companies.

Apple's Design Process

Apple has been using magnets for years in their laptops to replace mechanical switches and to help conceal latches so that there are no 'protruding' parts that could break off, or otherwise cause problems. I'm not surprised that they use them to help hold the laptop closed now.

Also, my new Dell m1530 has a magnet in the bezel to let the computer know when the lid is closed. Except Dell really didn't think out the design, as the bezel easily pops out, and so does the magnet...

 

no mention of stringent design testing process.

probably ASUS (apple's current ODM) is the one that do that.

if they did proper quality testing. why do apple's notebook, ipod, iphone, airport, all have overheating problem?

why do the magsafe adapter cord fried?

 

Making a laptop not overheat takes quite a bit more technical knowledge than HDD + magnets = bad.

Hint hint: if you know anything about hard drives, you know that there's a huge neodymium magnet inside the HDD. A normal everyday magnet won't do diddly squat to your HDD.

Seems they lie somewhere between the two at this stage.

 

hehehe "diddly squat"

thanks lithus! that link you gave me is gold!

how about moving/shaking your computer while the harddrive is still running?

 

Moving it around normally is not that big a deal, shaking it however can be hugely detrimental. Why would you want to shake your laptop anyway? Not like it's a baby or anything...

 

lmao

 

well... i'm just curious; when you go walking with your computer (with the harddisk still spining) or going up and down stairs with the computer still turned on, in a car/train?, etc.. well this is considered as shaking - no?

 

Let's just put it this way. A HDD can survive whatever a baby can survive.

Minus the milk.
