The green light on your power adapter is normal, this indicates that it is charging the battery. The fan within the MacBook is controlled by an internal heat sensor. The fan inside will speed up and slow down based on the internal temperatures.
The X icon for where the battery is, indicates that the battery is not connected or the system doesn't recognize the battery anymore. Meaning, you will need to buy a new battery for your computer.

Greetings Gurus. I have Makita charger model DC18RC, battery model is 18v BL1815...manual is of limited help. I'm trying to understand what the indicator lights mean, what the time is for charging,


I agree that the pictographs are not very helpful. You probably have one of the new chargers. I have an old one, which is a little easier to figure out.

From top to bottom

1. The flashing green light with the electric plug indicates that the unit is plugged in and ready to go.
2. The flashing red little fan means that the battery is too warm so it is just cooling it and not charging it at that moment.
3. The solid red empty battery outline means that it is charging but hasn't got very far, less than 80% full.
4. The mostly full battery outline with both solid red and green lights at the same time means it is 80% full or more
5. The full battery outline and solid green with the musical notes means it is full up.
6. The broken battery outline with flashing red and green means you've got a broken battery.
7. The yellow light with the wrench means the charger is "conditioning" the battery, whatever that means.
8. The yellow light with the fan means "cooling abnormality."

Hope this helps

Laptop not recognizing battery macbook


ifixit has teardown guides. The battery is probably dead, but the contacts could be dirty. The charger may also be bad. if the battery icon shows up in the top, it's probably connected properly.

Can not click on icons


Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

Macbook pro won't start/charge


It appears as if your power supply is dead. The power supply is inline with your power cord and has a light on it, if I am correct. Since the green light was dim, then went out all together on your power supply, that would indicate that it would not take a charge any longer, and the dim light, down to none, was the rest of your battery draining. Assuming you tried multiple power outlets, my suggestion would to borrow a power source from a friend and check it, or go to best buy/Apple store and have them use one of theirs to see if it comes on.

My MacBook wont charge


So does the organge light still not come on now? If it doesn't try a different charger first. If that fails, your DC-Jack module or logic board may need to be replaced. There are detailed instructions on how to do the restore online. Here is an Macbook Repair Guide that shows how to open a Macbook. If you want somebody else to do it for you go to Macbook Repair.

Battery level


As Suzaku explained:
A battery icon will show up on the LCD screen of your camera when it is already low and needs recharging. It can be found at the lower right side of your LCD screen. The ready light of your camera will also blink red and your camera will turn off if the battery is exhausted.
NOTE:
The icon will not appear if the batery is sufficient and there is no TECH way of making the icon show until the batt needs charging.

MacBook wont run from battery


Apple does have a battery recall/fixing procedure on certain macbooks and macbook pros.

The battery of a MacBook or MacBook Pro computer may:
  • Appear to have no charge (zero percent)
  • Be unable to power the computer by itself; the computer might work only when it is connected to the MagSafe power adaptor, which only shows a green LED
  • Appear with a black "X" icon on the menu bar

  1. Shut down, then remove and reinstall the battery. Test for the issue(s) again.
  2. Connect the MagSafe power adaptor (if you haven't already) and see if the behavior continues.
  3. If the issue(s) persist, download and install the Mac OS X 10.4.9 Update.
  4. If the issue(s) persist, Download and install Battery Update 1.2.
If, after installing the Mac OS X 10.4.9 Update and Battery Update 1.2, a black "X" still appears in the menu bar, contact apple by calling 1-800-MY-APPLE (1-800-692-7753)
