Apparently it's a common problem and may be due to a faulty batch of track pads, if it's still under warranty (ignoring the fact that you took it apart) it might be best to see if you could get it replaced.

Cleaning, I don't know, there's not much to clean as the trackpad is essentially an upside down optical mouse. If the surface is all scratched up that might affect it, polishing it might help, probably best to Google for tips on that.

P.S. I find it a little odd that you just happened to have a T6 screwdriver lying around. :p

I don't have a T6 screwdriver, I used one of those screwdrivers for eye glasses and now all of the screws, are well, screwed. *lol*

But yeah, thank you so much for the response, Nostromo.

I really do appreciate your post on this. :)

Then what is the significance of the matter in the universe contracting under gravity if it moves nowhere?
There is nowhere we can say it's moving with relation to any third object. The distance between all particles decreases, like dots on a deflating balloon.

Then which way does the matter go?
It.... doesn't. It gets closer together. From your point of view, everything would be moving towards you. From someone else's point of view, everything would be moving towards them. This is because everything is moving closer together.

Well, it would be, if that's what's happening. Current evidence suggests that not only are things moving apart, they're speeding up.

I love watching those kinds of videos. How indescribably amazing it must be to have an entire sense 'turned on', especially one as sublime as sound.
The sad thing is that when it comes to vision it is a different ball game altogether. The brain will need to learn to see and after a certain age this is not possible almost! So much for man being God's most perfect creation!

It's quite alright.

My worry now would be that because it will be clear to anyone who opens up your phone that you've already tried to fix it yourself, they might say you've invalidated the warranty. Some companies can be really strict, but a lady with a sob story can often make all the difference. ;)

Makes no difference; Cell phones are not made to last more than a couple of years and repair costs are too high. Just claim the new replacement phone at the end of the contract date or after every full year!:angel:

That's not such a bad idea if she's very near the end of the contract. I have no idea if she's on contract or not, and the GSM equivalent handset is still available new on contract here, so for all I know she could have got it last week. It also depends how badly the fault affects the functionality of the phone.

Personally I get attached to older, simpler phones. If I wasn't on a 3G network I'd love a Nokia 8310. :blush:
Which is just... sad, if you think about it.
It certainly is for me. You should see the reaction when I wear a mini-skirt :(

Same here! I have no desire to own miniaturised PCs disguised as phones. :thumbsup:

Can you fiddle with my words so it looks like i have said something i didn't say?
Yes. Though according to my e-mail notification, this is what you did say:

May i ask, is distilled coca cola and fanta original hash oil? what is it?
A quick look at Wikipedia shows that hash oil is distilled cannabis extract. Since neither Coca-Cola nor Fanta include cannabis, a simple distillation of them will not produce hash oil. I would not care to speculate on whether or not commercial soft drinks may or may not be used in the process, however.

If you put an ice cube into a vacuum container, sucked out all of the air, would it be possible to pull apart the covalent bonds and immediately turn the ice into water?
NO!!! Ice will melt with temperatures above melting point of ice (Space is full of ice in the form of comets and on planetoids devoid of an atmosphere). A vacuum however will allow the water to boil even at low temperatures.
Pressure and temperature combinations dictate the temperature at which water will boil.

It will sublimate (evaporate directly from ice), but not instantaneously. It won't turn into water, period.
