Troubleshooting Apple AC Adapter Issues Guide

Apple has laptop power adapters with a variety of connectors. Identify your ac adapter from the examples below before troubleshooting further.

How to Troubleshooting Apple Power Adapter Issues

  1. Make sure a known good outlet is being used.Verify that the power outlet you’re using is working correctly. Plug in a known good appliance, such as a lamp, TV, or clock, and confirm it powers on properly.
  2. Make sure the proper wattage adapter for your portable computer is used.Select the appropriate power adapter for your Apple portable computer. You can use a higher wattage power adapter, but you cannot use one with less wattage without potential operating issues.
  3. Identify line noise issues.Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
    • If the adapter works after this 60-second “rest”, you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the Apple ac adapter‘s “over voltage protection” feature senses ground noise and then turns off the adapter.
    • Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
    • Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
  4. Be sure you are using the adapter in a well ventilated areaThe power adapter may become very warm during normal use as heat generated during operating radiates from the adapter’s casing. Always put the power adapter directly into a power outlet or place it on the floor in a well-ventilated location. If you are using your MagSafe adapter in a poorly ventilated area such as on a couch, in thick carpeting, on bedding, or a pillow, or if the MagSafe adapter is covered by a blanket or other form of insulation, it may turn itself off in order to prevent damage to the adapter. The Apple A1304, A1369 Laptop Power Adapter may still be quite warm in this state and should be allowed to cool before handling.
  5. Check for possible AC plug (also known as a “duck head”) or two- or three-pronged AC cord issues.If you’re using the AC plug (also known as a “duck head”) with the power adapter, swap it out for the included two- or three-pronged AC cord, or if you are using the two- or three-pronged AC cord swap it out with the AC plug. Either connector can be easily connected the adapter as shown below.
    • If the adapter now charges the computer and the LEDs in the MagSafe connector are lit, the AC plug “duck head” or AC cord that was originally in use is no longer functioning and use of that connector should be stopped until a replacement connector is obtained. Refer to the Learn more section at the bottom of this article for further assistance.
    • If the LEDs do not work or the power adapter does not charge the computer, you should continue troubleshooting using the steps in this Article. Check for strain relief issues or stuck pins and dirty connectors.
  6. Check for strain relief concerns.Strain relief is a condition where the DC cable (the thin cord that attaches the MagSafe connector to the power adapter) separates from the end of the MagSafe connector or from the other end of the thin cord, at the power adapter. Under continued use, the cable may discolor and the rubber molding may become deformed.  Another indication of possible strain relief that is not always visible to the eye is intermittent electrical connectivity. You can often verify this condition by wiggling the cable back and forth near the MagSafe connector and observing whether the LED indicator (which turns amber or green) flashes on or off depending on the position of the cord.

    You should not use power adapters that have strain relief damage or that are missing insulation or rubber. Do not attempt to repair an adapter cable in this state.

  7. Check for stuck pins on MagSafe Connectors.Sometimes you may discover that the MagSafe adapter for your computer is not working properly because the pins inside the MagSafe connector are stuck.

    For example, the pins on the connector of the MagSafe adapter shown below are stuck down.

    Example of ground pins on adapter sticking. This may cause the adapter to be seen but it may not charge.

    Example of the sense pin on adapter sticking. This may cause the adapter to charge but not be seen and may cause the LED on the adapter to stay dark.

    If you think that a pin is stuck down, try unplugging and re-plugging the MagSafe adapter into the power port. The pins should move and reset themselves to a neutral position. If you find that a pin isn’t resetting itself, gently press the pin sideways using a fingertip or other soft, non-scratching surface to see if the pin will reset itself.

How to extend Apple Macbook laptop battery run-time

Laptop battery performance is a major concern of most mobile Apple Mac users. You can extend battery run-time using a host of battery conservation methods, from the obvious to the silly. Today Australia leading batteries supplier: AussieBatt experts share the tricks for Getting the Most Run-Time from Your Apple MacBook.

Prolong Macbook’s Laptop Battery Run-Time Tips

Manage Macbook Energy Use – The Energy preference pane in System Preferences allows you to manage your Mac’s energy use. There are multiple options for conserving battery life, including turning off the display and putting drives to sleep. The Energy preference pane is the best place to start with battery conservation.

Spin down your Mac’s hard drives. You can use the Energy preference pane to put your hard drives to sleep when they’re not being used. That’s one good way to conserve battery power. Turn off keyboard backlighting. This feature uses an ambient light sensor to determine whether the keyboard needs to be illuminated in low light conditions.

Turn Off Unused Services

Your portable Mac has many built-in services, such as AirPort and Bluetooth, which can be turned off if you’re not using them.

You can disable AirPort or Wi-Fi if you’re not using this feature. Doing so will prevent your Mac from continually scanning for active wireless networks, or making an automatic connection to a network. Either way, you’ll save Apple MacBook Pro 13″ A1322 battery power by turning Wi-Fi off.

Bluetooth is another energy drain that can be disabled if you’re not using it. Launch System Preferences, and select the Bluetooth preference pane. Remove the check mark from the On box.

Turning down display brightness

Turn off background notifications. Many applications have a background utility that runs all the time to check whether the app has any updates pending that need to be installed. These pesky mini apps use your Mac’s memory, CPU, and network. Turning them off when you’re running your Mac on its battery is a great idea in theory. Muting sound is another way of reducing energy usage. By turning off your Mac’s built-in speakers, the battery won’t be used to generate all of the default squeaks and squawks associated with various events.

How to save Asus A32-K72 laptop battery power

With a price tag under $1000, ASUS K72 series laptop offers a nice balance of performance and features including a very comfortable keyboard. There are some big drawbacks to the laptop though including a display that doesn’t support full 1080p, below average laptop battery life and a lack of many peripheral connectors.

Laptops can consume large amounts of battery power, as a result, a laptop battery can suffer a shorter lifespan due to it being strained by your laptop’s activities which may require them to be replaced sooner than its expected lifespan. You can take steps to prolong the life of your battery as well as help it preserve power while it is not being charged.

Preserving Asus A32-K72 Laptop Battery Power Tips

  1. Shutdown or activate sleep mode on your laptop when not in use. If you need to leave your laptop off for long periods of time while off the charger, place the laptop in sleep mode to leave your operating system in its current state and will resume from that point. Shutting down the laptop will require you to go through the boot up sequence that may consume additional power. You can close the lid or press the sleep button on your laptop to put your system in sleep mode or press the power button to allow your laptop to go through the shutdown sequence.
  2. Turn off wireless and bluetooth settings. Your laptop is always seeking for a connection when wireless and bluetooth functions are active. When working away from bluetooth devices or areas with a network connection, disabling these features will stop the laptop from looking for devices to connect to. Disabling these settings will vary depending on your operating system.
  3. Unplug devices from the laptop. Any device plugged into the laptop, such as a USB device or a second monitor through VGA, will require CPU activity to access these devices. Certain USB devices will require a high amount of power which will drain the Asus A42-G73 Notebook Battery faster, such as a fan which features moving hardware. Unplug any devices that you do not need to use.
  4. Activate Power Saver Options on your Operating System. Your operating system will modify hardware and software behavior that reduces their activities and use less power from your laptop. Power options have the ability to change the behavior on your laptop’s hardware such as your CPU or hard drive to only become active when needed for certain actions. Otherwise, your hardware becomes inactive after a short period of time to conserve energy.
  5. Keep your laptop and laptop battery in cool dry temperatures. Keeping your laptop in a well ventilated area while resting a hard surface to increase airflow to the laptop. If working on your laptop in a bed or on a carpet floor, consider using a small tray to place it onto.
  6. Remove the Asus battery from the laptop when powered by the laptop AC Adapter. If the laptop will be run primarily using the AC Adapter, a fully charged battery holds onto more energy that will cause it to wear out faster. To remove the battery locate the battery on your laptop and unlatch the clips holding onto the Asus a32-k52 notebook battery. There may be one or two clips that can be slid to their opposite ends to allow you to pull the battery out.

How to cool down your laptop for longer battery life

Heat is one of the worst enemies of laptops. Laptop batteries age more quickly when they’re hot for a long period of time, and overheating can destroy other hardware parts, causing system freezing and worse problems. Whether or not you’re experiencing the warning signs and dangers of your laptop overheating, take the simple and inexpensive protective measures below to keep your laptop cool and make it work more reliably.

Easy Tips for Making a Hot Laptop Cooler

1. Use a laptop cooling pad that has a fan or two.
 Laptop pads that have vents but no fans can also increase the airflow around your laptop and they’re very portable, but for stronger cooling needs, a fan is the best way to go.

2. Use dust remover spray to clean out of the laptop’s vents. Dust can accumulate in and block the laptop’s fan vents — a problem easily solved with a can of compressed gas. Turn off your laptop and spray the vent to remove the dust.

3. Keep your working environment or computer room as comfortably cool as possible. Laptop computers, like most people, work much better in air conditioned environments. Most server rooms or data logger centers operate at 70 degrees or below, according to Server Fault, and that seems like an ideal temperature recommendation for home offices as well.

4. Adjust your power settings from “high performance” to a more “balanced” or “power saver” plan. This will tell the system to only use the Dell latitude e6400 battery power required to run your applications, rather than always using the maximum processor speed; if you need to play games or other intensive work, you can switch back to the high performance plan as necessary.

5. Shut down your laptop computer when not in use, and especially when you are not at home. The last thing you need when you get home is to find out your laptop was a fire hazard.

Power Tool Batteries and Drill Battery Charger FAQs

Cordless drill is very handy in a pinch but don’t trick yourself into thinking that it can handle everything. If you ever get to the bigger projects you’ll need a corded set of tools. Such as deck building. Not a chance in hell that a cordless tool would have done much good in that situation.

Before you purchase a new cordless drill, it is useful to learn more about how the power tool batteries and charger work. This will help to ensure you are using the drill battery and charger correctly so that you can get the best performance from your power tools.

Power Tool Batteries and Drill Battery Charger Usage Tips

Can I use a 9.6V drill battery in a 12V Cordless Drill?

No, you cannot use a 9.6V battery in a 12V drill. The power tools are designed to run at the specific voltage provided by the battery pack. Too much voltage, as well as too little voltage, it can cause poor performance and life from the tool. The drill may run for short periods of time with the wrong Makita 1835 Drill Battery Pack, but it shortens the overall life of the product. This is the same reason corded products designed for 240V cannot be used in the U.S. where they have 120V outlets or vice versa.

Does the Battery Need to be Completely Discharged Before Recharging?

No. Just the opposite, you should stop using a power tool battery as soon as you feel a substantial decrease in power from the tool. Completely running down a Makita BL1830 Tool Battery may damage the power tool battery. Do not tape the trigger to run down the drill battery.

Why does my Power Tool Battery not hold Charge Anymore?

A drill battery may not hold charge for any of the following reasons:

Can you Leave Cordless Drill Batteries in the Batery Charger?

This entirely depends on the charger supplied with your power tool and you must read your owners manual to answer this question. In some cases serious damage can be caused by leaving your drill battery on charge, whereas in other cases it is recommended that you do leave your unit on charge. For example DEWALT chargers have a maintenance mode which allows batteries to remain in the charger, maintaining a fully charged pack until the user is ready to work. If the batteries are stored outside of the charger, they will discharge naturally, 15-20% the first 24 hours, 7-10% the next day, and about 1 % every day there after.
