Not without some qualifications. The issue is when using a less-than 85 watt charger on a MBP that requires an 85 watt charger. The MBP can require as much as 85 watts under heavy CPU and/or GPU usage. Trying to pull 85 watts from a 60 or 65 watt charger used by most MacBooks or the 45 watt charger used by the MacBook Air can lead to potential problems of possible overheating or over-current issues in the charger itself.
Nope, Ohms law has yet to be repealed, the current drawn by the load will increase until the supply maximum is reached, then it will stay at that level until full charge is achieved. The supply will deliver up to its maximum specified wattage and can do that without strain.

My iPod 5th generation charger doesn't work but it says it's charging. When I use another person'a charger, the iPod charges fine. Has anyone had this problem?

Yes, the Lightning cables do fail sometimes. They are covered by the same one-year warranty as the iPod

Content disappear when use another mac to charge iPod

I am a new user of iPod, I loaded my ipod shuffle from a desktop Mac, then try to charge the iPod battery using a MacBook, then the content of all loaded songs disappear from iPod, I suspect it try to automatically sync with the songs in MacBook, but there is none in the MacBook.
If so, how can I stop this from happen, if not, does it mean that I can not connect my iPod to another computer to charge t?

As recommended, in Settings in iTunes, I UNchecked "Open Itunes when this iPod is connected" in both computers and click "Apply". but then when I connected it to MBP, the indicator amber light is blinking constantly, and I have to open the iTune, and then the light turns green, but the content was wiped out, the option for :"Open itunes when this iPod is connected" is indeed unchecked. so I am back to square one.
so I have to use decktop mac to load the music again. by the way, the reason I need to use MBP to charge the battry, is that the iPod when connected to desktop Mac has constant blinking amber light unless I plug it to MBP first, but then the content disappear.

You can use a charger from another MBair or Macbook Pro that's the same or higher watts.

i am sorry i not good speak english

Provided you are using the correct charger for your Mac (13" have a 65 watt charger, 15" and 17", an 85 watt charger), it has enough capacity to power the computer for normal tasks, and the leftover power can charge the battery at the same time. If you are doing something very intensive, there may not be leftover power, but the Mac will take power from the battery if needed. Once the battery is fully charged, the pilot light in the charger plug will change from orange to green and no further charge will be applied to the battery.
You can use your Mac plugged to the charger with no damage to the battery or the computer.

The battery for my Macbook Pro 13 "has only 121 cycles and is not charging anymore, my Mac is telling me that it is necessary to exchange it. You have any tips for me to find out what might be happening with my battery?

Guys, i am actually trying using a solution provided by the article shared by dominic23,
It says "Another option is to get an ionizer to help the atmosphere in the workplace be more conductive and pull charges away from contact surfaces, including yourself."
So in my home, we have such device that could clean the air using ion, and i am using it in my room...
Result: BANG!!! The electric shock on my macbook has gone!! I don't really care about physics but somehow it works! You guys should give it a try.
Thanks again dominic23

Can i use a 85 watt charger for my macbook pro that came with an 60 watt charger?

My charger broke a few weeks ago and i ordered another one on amazon and that broke within a week so i'm going to just buy another one from the apple store. But i dont want to wait to order one because i currently cant use my laptop since it died (i dont live near an apple store), but theres a store that sells apple products. they only have 85 watt for the laptops though. so would i be able to use that without ANY issues? I would rather order from the apple store than to buy something that can cause problems, so i just want to know if my macbook will be safe if i use an 85 watt instead of the 60 watt, which is what originally came with my laptop. Thank you.

An 85 watt charger will be fine. Generally, you can use a higher-powered charger than the one that came with your MBP - but using a lower-powered charger is not recommended.

It may well be a driver issue but considering the loading: Xorg trying to load different drivers is somewhat normal. @cafe you can see that these are autoconfigured by X above the loading in the log:
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 0
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 1
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched modesetting as autoconfigured driver 2
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched fbdev as autoconfigured driver 3
Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched vesa as autoconfigured driver 4
As long as one of the drivers gets loaded, which it apparently does the failing of the others is fine.
Was there an update maybe ?

The amount of RAM is not dependant on the operating system. It is all about the model of you Mac.
10.6.8 is the version of OS X that is installed on your system. It has no real baring on the amount of RAM that CAN be installed.
Personally I have never had good luck with Corsair RAM. I have always had good luck with Crucial and Kingston.
