Tips for maximizing apple battery charge

You can take some easy steps to prolong the charge of your Apple Macbook battery portable’s .

Here are some simple settings and steps you can take to get the most out of your MacBook, MacBook Pro 13 inch battery , MacBook Air, iBook G4 or PowerBook G4 battery.

Optimize your battery settings in Energy Saver preferences

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Energy Saver.
  3. Click Show Details.
  4. Choose Battery or Battery Power from the “Settings for” pop-up menu.
  5. Choose Longest or Better Battery Life from the Optimize Energy Settings pop-up menu.

These settings will put the hard disk to sleep whenever possible and reduce the computer’s microprocessor performance in order to maximize its Apple A1175 battery life. If you are using processor-intensive applications, you may wish to change these settings so the microprocessor performance is no longer reduced.

Set your screen brightness to the lowest comfortable level

Press the F1 (dimmer) and F2 (brighter) keys to dim the screen until the brightness is as low as possible and the screen is still comfortable to look at.

Turn off unused features and technologies.

Just as you would turn off the lights in an unoccupied room, turning off unused features and technologies can help maximize your Apple A1185 battery life, too. Here are a few suggestions:

  • Eject CDs and DVDs you’re no longer using. Every so often, the optical drive spins up to read CDs or DVDs. This consumes a small amount of power.
  • Disconnect peripherals when you’re not using them. Connected peripherals, such as printers and digital cameras, can draw power from your Apple iBook G4 12 inch Battery even when you’re not using them.
  • Shut down any runaway applications

If you’re not in a location where you need to use AirPort or Bluetooth, you can turn them off to save A1008 A1012 power.

To turn off AirPort:

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Network.
  3. From the Show selection, choose Network Port Configuration.
  4. Uncheck Airport from the list.
  5. Click Apply Now.

To turn off Bluetooth in Mac OS X 10.2 or later in Apple A1057 A1060 :

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Bluetooth.
  3. Click the Settings tab.
  4. Click Turn Bluetooth Off.

My shoppingg experience buying Dell inspieon E1505 accessories

Dell-Inspiron%20E1505-laptop

Two month ago, my Dell E1505 battery failed after its 1 year warranty. So I should buy a new one for my coming holiday in Hawaii. Now I will never shopping in Ebay or Amazon. As you know you buy someone there, and no guarantee of the product, also the money refund is impossible. And you can not cancel the order. So I decide use my paypal to buy the Dell inspiron E1505 battery.

I searched the Inspiron E1505 Battery in google and found search resault. Then I click some of them, after long time comparison I order a battery from http://www.discount-laptopbattery.com as Its price and 30 days money back and one year quality warranty. After 7days I recevied the battery and below is my battery using experience:

I was getting three red flashes and one green flash continuously on the battery light on the lower right side of the lid which according to the manual means defective battery which turned out to be true. I trashed the cheap Latitude D820 Battery (which I noticed was rated at 5200 ma vs the rating of 7200 on the Amazon battery)because I did not save the receipt. I am thrilled with this battery which is giving me about 3 hours before needing a charge, and charges to 100% overnight with no problem.

It works well with my 1505. I got 4 + hours out of this per charge. Saw some other people having problem with recognizing the batteries. When I was doing research for purchasing a replacement Latitude D620 Battery, I came across a lot of discussions online about Dell laptop not recognizing batteries. I wonder if that is a common issue with Dell. Luckily, mine has no problem. :) Everything is good. As long as it can last 1 year or so, It would be worth the money spent.

Owned for 5+ months. I am pleased with this Latitude D830 Battery I was glad to find it at a price much lower than Dell was selling it. It was a great buy. Product came right when I needed it and has worked great for me! Good battery life.

In all The battery is compatible and works well with the Vostro 1000. Instructions are confusing. I simply installed and followed good battery practices – completely charged the battery, completely drained the battery, then repeated.

In the end I saw some New batteries in this online shopping are in 35% price discount as the Merry Christams Day coming. I list them below with the brands:

Apple : A1008 Apple A1061 Apple A1148 Apple A1057 Apple iBook G4 12 inch battery Apple iBook G4 14 inch battery

Repair battery step one : calibrate your cell

First of all, the test voltage to zero, the machine can not start naturally, can not use power when charging (the battery light does not shine).

Disassemble the battery, more or less talk about the situation inside the battery.

Battery in a total of 9 can be placed 18 millimeters in diameter, length 65 mm core CGH18650 models the location of lithium batteries, Panasonic’s 22 batteries in parallel, three groups of series (OK, then my new Latitude D620 battery, the same, it appears that is 6), there is a very fine control with a single chip – the protection of the circuit, the circuit to the computer a total of five output contacts, respectively, are negative, the clock and data.

First of all, check the sticky in the battery temperature detection probe (temperature resistance), and temperature protection insurance, are also normal. Test-retest the battery voltage of each group, in which two sets of battery voltage of 3.8V, normal; a battery voltage of 0V, appear to have lapsed. The total battery voltage of 7.6V, then the failure of the battery pack has not yet open, then measuring the internal resistance was very small, almost in a state short-circuit.

First of all, failure to deal with Thinkpad T60 batteries, battery repair based on previous experience, the failure of the battery may not be completely damaged, can be activated through a number of methods, in particular the performance of state for the short-circuit the battery. The voltage of the battery to 0 with one end connected to the circuit board off line to avoid damage to circuit boards in operation. Open-circuit battery voltage after the re-survey, is still 0V, ruled out the possibility of short-circuit boards.

For short-circuit the battery failure, the method is more effective high-voltage electric current moment method, using the old IBM power supply (my back-up power), 16V maximum 3A output string on the multimeter (a tributary of the current file 20A), first negative power supply Even with the battery anode, and cathode power multimeter then red table pen, table pen with black multimeter battery cathode touch, speed, faster as far as possible, the former two degrees to see the multimeter has reached close to the 2A (moment) and the third on only 0.4 A about an immediate stop, measure the battery voltage has been restored to about 3V, the internal battery short-circuit that point has been an instant high-current boil (If you do not damage the battery to stop immediately, even if so, battery life and capacity have been the impact, if conditional, or recommend replacement, but if the replacement, then try to replace the entire battery pack are). However, the batteries need to be a separate charge (if the battery charge of the whole group, this will result in the other two groups had mesenchymal cells), plug in the charger to start charging ammeter to monitor during the charge current to 500mA or so, current for the 3.6AH battery pack is small, but the charger is the charge current is limited and a small current to the xps m1330 battery charge is good for the resumption. After about six hours, the charger showed the battery is already full, continue to re-charge for about two hours, remove the battery, measure voltage has reached 4.2V, with bright halogen bulb in the flashlight (3V, 500mA) to discharge its , bulb sharp discharge current of 700mA, the battery pack that has been basically restored, continue to discharge until the battery voltage down to 3.8V, the purpose of the two groups with the same battery voltage, charging time together so as not to overcharge the Back to the whole battery pack battery circuit welding.

Since the inspiron 6400 battery voltage while the circuit board there is no output, then, surely have damaged circuit boards, after observation, negative input circuit board (take battery) output (then output contact) is directly connected, and the positive input and output of by a high-power thyristor control, the thyristor remains cut-off state, that is, the control circuit has not been output control signals to the SCR control terminal, or simply the SCR has been destroyed. (Measured after the control signals that I did not) because I do not have the ability to repair single-chip microcomputer. IBM to take into account the protection of the BB more perfect, is about to run out of battery power will automatically shut down when, this battery is intended to be used for entertainment, therefore, need not be too concerned about, so I decided to shake the hp battery protection circuit, directly depend on BB’s protection circuit. SCR is in the input and output pin (that is, cathode circuit board input and output pin) between the solder on a small 2A fuse, fuse 2A select the reason is based on current usage, the largest in the computer power consumption , the current does not exceed 1.9A, 2A capacity sufficient unusual circumstances (for example, short-circuit accident) but also to ensure that the fuse of the time, but also play a role in protection.

In fact, directly to the SCR control terminal so that it can also be a high turn-on, but taking into account the current the battery must be a reason to burn, and the reasons for the identification of protective measures taken before or better in order to avoid greater loss.

Well, the battery power has been the first non-stick, and on the machine to try it! Normal boot, plug in the power immediately after the charge on the flashing lights are up, the way when charging the battery with a random look at battery information management software, was also displayed, the battery circuit board This shows that the single chip is still working.

Batteries battery is a Panasonic, the time the factory in June 2000, the first time in October 2000, the design capacity of 38.88Wh, the current capacity 38.88Wh, is charging cycle: 0 times.

Oh, do not know how to engage in, the inspiron 1300 battery may be burned when burning confused, even cycles to the zero, Now it maybe a new battery.

 

 

Repair battery step two : repair battery shell

Points and then encountered trouble: it was soon filling power (twice as fast than normal), in the course of discharge to 70% of the time will suddenly prompt “The battery is dead, please insert the AC power supply” warning capacity to show an immediate 5%. The beginning of a long time thought it was not using the battery leads to memory effect, we should do like a few of the deep cycle. But after several full charge, after release and found that the improvement is very small, only about 45 percent take power, with half an hour, we still have the problem. The largest may be the Inspiron 1520 battery pack in more than one section or “black sheep” in trouble, have to pull it out!

Red several times in the subsequent discharge cycle every place is full of electricity and have finished after the battery power to open, measuring the voltage of each battery pack to find a group of “different”: the per-charge when it voltage to reach 4.2V or even more than the first, leading to cessation of the entire VGP-BPS2 battery charge, and discharge when it was first to reach 3.6V or even less, is a typical decline in capacity. And the largest of which may still be a battery problem. This group of cells separated from the measurement of voltage, respectively, found that a battery voltage is low, only about 3.2V, a separate charge of their voltage quickly reach 4.2V, less than a minute of time, The A1185 battery basically has no capacity to speak with a light bulb when the discharge was found, it has the fundamental output current that can not provide even less than 1mA, measuring its resistance, has reached more than 2K seems to have been scrapped.
As a result of a “shock therapy” after the restoration of the normal cells, but not charging voltage reached 4.0V, it seems that it is “the pot boiled dumplings – do not put out an electric” soldering it back a battery discharge followed by the use of time of up to 90 minutes, has been near normal level of the battery.

However, when the charge is quickly filled, and disturbed mind up soon. Was a discharge, it is less than half an hour, open a test, just fix the bad and the battery.

Not always have to use a “heart to recover,” ah, so the value on the lost.

This section of the final decision to do a battery operation, and then they can not, then replaced the batteries. Peeling of the batteries, removed the insulation near the cathode cap and found a slight corrosion around, but I do not like battery leakage and traces, as well as save. With halogen lamp from the battery positive and negative, there is no response Taking into account the previous “Anatomy” the same symptoms when the batteries are inside the battery with the battery cathode output between cathode cap (the pressure on, not welded) oxide occurred, resulting in increased resistance and end-of-life battery , and the internal battery is still good. Oxide layer in the case is not serious as long as the battery cap to strengthen the internal contacts and battery resulting in the battery does not leak if damaged can be restored. The simplest way is to step up the battery forceps are negative (one pad insulation film), while measuring the inspiron E155 battery output voltage (or current), while vertical extrusion batteries, once the battery output voltage is increased, the current increase (the change is often the jumping in nature, relatively large changes) to stop immediately, the battery will be able to repair.
The top edge of the battery cathode cap next to the mouth ventilation valve with cutting pliers, then immediately measured and found that the battery has been restored, the output current increases immediately. In order to insurance purposes, the battery cap in the week between the edge of the chisel a few more in order to increase the contact area to ensure that the use of effects.

The battery to re-wrap, solder back to the XPS M1210 battery pack, charge, discharge. The use of time to reach more than 90 minutes.

Again measured with test software and found that the current capacity of smaller 38.88Wh from the original into a 32.07Wh, a decrease of nearly 20 percent, but this is the real discharge process, there is no jump of dropped. After several red discharge cycle, the capacity has increased by some. Use has been made to the current two months, everything will be all right.

How to Calibrate laptop battery

After using for months, the battery get weak and cant fully discharge. Also in this situation the laptop battery’s 76% even less in work.Now we need to Calibrate laptop battery. I found a note about recondition laptop battery from Dell laptop battery manufacturers handbook. Surprisingly, it offered some really helpful laptop battery calibration and maintenance tips, which Id like to share with you:

Calibrating a Battery Pack

When to Calibrate laptop battery
Even if a battery pack is heavily used, it should not be necessary to calibrate it more than once a month. It is not necessary to calibrate a new Dell GK479 pack before first use. However, make sure that the battery pack is fully charged, especially if it is the only power source.

Calibrate Dell 1721 Battery ack under the following conditions:
? When the battery status display seems inaccurate.
? When you observe a significant change in normal batteryrun time.
? When the battery pack has not been used for one monthor more.

How to Calibrate laptop battery
To Calibrate Inspiron 1501 Battery pack, you must fully charge, fully discharge, and then fully recharge the battery pack.

Charging the Battery Pack

Fully charge the Apple A1185 battery pack when the notebook is in use. To charge the battery pack:
1. Insert the battery pack into the notebook.
2. Connect the notebook to external power through an AC adapter. (The battery light turns on.)
The battery light turns off when the battery pack is fully charged.

Discharging the Battery Pack

Disabling Hibernation
To fully discharge the battery pack, disable Hibernation temporarily.
To disable Hibernation:
? Select the Power Meter icon on the taskbar or access Power Options > Hibernate, and clear the Enable Hibernate support check box.

Discharging the battery Pack
After the battery light turns off, which indicates that the battery pack is fully charged, begin discharging the latitude d520 battery pack.

    To fully discharge the Sony battery pack:

  1. Select the Power Meter icon on the taskbar, or select Start > Control Panel > Performance and Maintenance > Power Options > Power Schemes.
  2. Write down the 3 settings in the Plugged In column and the settings in the Running on Batteries column, so you can reset them after calibration.
  3. Select the drop-down lists and set all 6 options in both columns to Never.
  4. Select the OK button.
  5. Disconnect the notebook from the external power source, but do not turn off the notebook.
  6. Run the notebook on battery power until the battery pack is fully discharged. The battery light begins to blink when the battery pack has discharged to a low-battery condition. When the battery pack is fully discharged, the power/Standby light turns off and the notebook shuts down.
    Recharging the Toshiba laptop Battery Pack

  1. Connect the notebook to external power and keep the notebook connected until the battery pack is fully recharged and the battery light turns off. ?You can use the notebook while the battery pack is recharging, but the battery pack will charge faster if the notebook is turned off.
  2. Select the Power Meter icon on the taskbar or select Start > Control Panel > Performance and Maintenance > PowerOptions > Power Schemes.
  3. Reenter the 3 settings you wrote down for the 3 options in the Plugged In column and for the 3 options in the Running on Batteries column.
  4. Select the OK button.

Now you already Calibrate laptop battery

Use different stand to cooling the laptop

If your latop’s cooling system is working properly, you can still do more. Strange fact is that when you use a laptop with a laptop battery on your laptop, you always ask for laptop overheating. Any soft objects may be blocking the cooling system of the ventilation holes. It also can cause heat to get caught underneath the unit. That is why people would burn their laptop.

However, heat buildup can even happen when the laptop sits directly on a desk using a laptop battery.

There are different ways to avoid this buildup. A latop stand to keep the bottom of the notebook and your use of the surface of the table some distance intervals in Apple A105 and Apple A1079,. It created the basic space, the heat can disappear. A type of stand are usually flat, legs are short, thin surface of the type, you can lay in your lap or desk. With an air-inch notebook PC 2, the heat can easily escape, and the airflow through the vents have been completely open.

Sometimes, a stand may be caused by an act of special materials such as aluminum heat in Inspiron 1100 Battery,. This device will actively utilize heat out of notebook cooling further assistance. Another approach is to a laptop pad or pad. In this approach, we hope that with the aluminum heat sink, you put the device active thermal management surfaces. This could mean that trap heat insulation pad notebook coming out to protect your lap. It could also mean that, on the positive development of built-in cooling fan out of thick pad.

Although you can from any electronics store or retailer to buy dozens of these cool online tools for your Inspiron E1505 Battery, one of the things you might at home, and now you can use. A small strip camping tables can be used as a stand notebook. Therefore, we can use large baking rack (can be used for cooling cookies) to do a stand.

One thing to remember is that the heat characteristics of your laptop are always changing, depending on age, environment and power usage. So even if you get yourself the perfect cooling setup, you might want to install some sort of heat-monitoring software in PA3450U-1BRS, PA3451U-1BRS. It’ll help you be more aware of your laptop’s fluctuating temperatures and learn how different situations can increase the heat.
