The 60 Watt MagSafe Power Adapter features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection. When the connection is secure, an LED located at the head of the DC connector will light; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge.
An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter also provided gives users an even easier and more compact way to travel. Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage. This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode.
It also powers the system if you choose to operate without a battery. See this article for more details about choosing the right one. Knowing which specific Mac model you have is important. If you are running OS X Lion Your Mac model and generation will be displayed. If you are running an earlier version of OS X, you can enter your serial number here to find out which model you have.
If you have both cores going full-throttle, the battery will be always discharging until it reaches a zero charge state. The rate at which the battery charges will also depend on the machine load. With an 85W adapter, that leaves about 55W for the machine, and it's insufficient to power a full machine load. With a very high machine load, the charger is left with very little power to use, even with an 85W supply, and will take very long to charge the battery.
Finally, the supply's electronic nameplate is stored in the chip residing in the MagSafe jack. If the MagSafe jack is damaged or doesn't have the nameplate chip, the power manager does two things:. You will not harm anything using the incorrect adapter. The charging circuitry in Intel Macs is very sophisticated and won't let anything bad happen. Using the higher-wattage adapter with a low-power-requirement notebook will work.
The computer will only draw as much power from the adapter as it needs. Using the low-wattage adapter on a high-draw notebook will result in the adapter powering the computer OR charging the battery, but not both. If the computer is asleep or shut down, the battery will charge at a normal rate. Please take into consideration that this might be completely unrelated, probably.
Plus my battery was replaced at no cost in an Apple store Macbookpro late , 1st gen unibody while I'm still not sure if Applecare also covers the battery on 3yrs. Do NOT use a lower-than-spec'd power-supply with your portable. It will power on, but will be running in a brown-out condition, causing shortened life due to excessive heat.
We found this out the hard way with an after market power-supply on an iBook. It was just under the needed power output, causing the unit to always run hot, and eventually shutting down because of too much heat.
After several months it got so it would run for minutes then turned off, and eventually quit entirely. We tried getting it repaired, but it was too far gone. I took a close look at my '65W' adapter. Apparently, it's not a 65W adapter after all, but an 85W with the older connector the fat head connector. I always assumed it was 65W because of the age of our MBP I guess the guy we bought it from used had replaced the adapter. You may want to check yours closely since they can get mixed up.
I have been using the 60w adapter from my old 13"macbook pro which was stolen a while ago for my new 15" macbook pro for about a month because I assumed that all the cables or adapters are the same from Apple since it is the case for the usb cable and I did not realize until one day it turned off itself.
Most of the time, my macbook pro was connected to the power. Now I have switched to the 85w adapter and everything works fine, thank god. Apple has added a support page to break this down. Note that the power adapter square block is a separate from the cable on USB Macs. I'm using a 60W power adapter for my 15 MacBook Pro. It runs fine if I'm doing light tasks, however, if I'm running an intensive application like Starcraft 2 on Bootcamp the battery will stop charging and drain very slowly.
I swapped the adaptors and it works fine for both machines. Also, the MacBook Pro using the 60 W power adaptor is charging the battery, although it is a little bit slower. Is it a good idea? Does it work? The wattage rating is matched up with your particular laptop's needs.
If you use a lower rated power supply, in many circumstances it will work ok, it may just charge a little bit slower. If your laptop is powered off, it'll charge decently fast too. However if you then boot into something less power efficient like linux or windows, you'll notice that despite being hooked up to a power supply, you are slowly losing battery life because there's simply not enough wattage to drive the whole thing and a lot of the power saving features aren't properly implemented.
This also can be an issue if you have modified the hardware in your laptop, or if you try to do heavy gaming anything that gets disks and fans spinning. If this is your situation, you can still use the lower power supply, but you're going to eventually hit a point where the transformer will overheat really bad , or you will just run out of power.
So in a perfect world, you should always have the adapter that apple intended you to have or a higher rated one. But if you have to use a lower rated one for a little while it won't be the end of the world. I don't think this talk of "Brown out" is correct. The MacBook will always have enough power from the battery to operate without "Brown out". It's only when the battery gets critically low that the computer may think it's getting sufficient power to operate as it's plugged in but will probably be in a reduced performance mode due to the low voltage of the battery.
This will manifest as operation of the computer being sluggish. As a battery nears "empty" it will produce more heat, so despite being in low performance, this may cause the fans to spin up, even though the computer isn't doing as much. If you're storing a laptop, make sure you charge it before hand and periodically top it up. If possible, remove the battery as this will slow the discharge. So I believe that a low wattage adapter is fine if you only use it to charge the laptop when it's sleeping or off.
Puffed batteries are always a symptom of fully discharging it. I have experience with RC batteries that have no intelligence built in. There is however some management built into the systems they're plugged into. Sign up to join this community. The best answers are voted up and rise to the top.

Apple's official word on the matter is: Make sure the proper wattage adapter for your portable computer is used. So your 13" can use your 15" charger, but not vice versa. Improve this answer.
The issues are the battery may not charge at all or rapidly.
