when you have chance to plug the adaptor while using, then do so.
but remember to discharge and charge till 100% (1 Full Cycle) atleast once a week

or this one
http://en.wikipedia.org/wiki/AC_power_plugs_and_sockets

basically it's down to the standard of country. Malaysia Standard (might) not enforce proper grounding in every building (maybe has been done in new built area)

quote:
"Japan also uses a grounded plug similar to the North American NEMA 5-15.[39] However, it is less common than its NEMA 1-15 equivalent. Since 2005, new Japanese homes are required to have class I grounded outlets for connecting domestic appliances. This rule does not apply for the outlets not intended to be used for domestic appliances, but it is strongly advised to have class I outlets throughout the home."

So basically, the socket itself is grounded, and there are running 2 phase

Anyone know the price for a Macbook white charger?
Should be same with macbook pro.

60W Magsafe should be RM249.

My mbp suddenly cant charge.. Connect the charger but the led on the magsafe charge not light up (green or orange).. Been try other power point still the same.. With extra long cable or with 3pin adapter still same..

Need advise please..

MBP 13" late 2011
2month out of warranty..

Try reset PRAM on your mbp...SMC reset.. Anything about reset you can google bout it.

Check your charger tip is all the pin are rise up. And Mac side, see if the port have any alien object it.

Else you try to test the charger on another Mac and loan a working charger to test is its your Mac and charger problem.

thank god it work now..

did the pram and smc reset but no work.. what i do before it work.. safely unpluged the power cord from the adapter cleaning the pin inside the adapter.. then connect together, power on, it light up.. at first the orange light blink and turn off.. after several attempt it works good.

thank a lot guys for the help..

Hi. I'm considering to upgrade my ram to 16GB (MBP 13' Mid 2012)

Apple Original Ram is too pricy and I afraid I cannot afford it.

well I'm considering Crucial's Ram.

And I heard some rumour that although Apple has stated MBP 13' Mid 2012 can only recognise up to 8GB ram, but somehow there are people trying for 16gb ram and the result was encouraging.

I wish I can get some opinion from you.

Wrong topic for asking upgrade.
I believe this photo says it all:

Yeah I know it is a little of off-topic

but it seems like you know much about those technical things

so I asked at here.

Good pic btw.

Then how about using ram of other brand? (Crucial or whatever)

I believe there are plenty of discussion on that already.

Hi I'm new to Mac. Just curious with my battery stats. Is it normal? Thank you.

That depends how old is your unit.

Based on that stats mine is 4.3 months old.

The age on coconut battery is estimated based on manufactured info on the battery. If that is correct, your usage is consider normal.

Ok thank you.
