Power Management in Windows XP

All the battery spec info are from Laptop battery

Power Management in Windows XP

As laptops have gotten smaller, thinner, and lighter, they've had to sacrifice the longer-lasting power that comes with large batteries. But at the same time, laptop chipsets and processors have gotten smarter about power management, making the most of these smaller batteries. Windows XP provides several options to manage the power consumed by your laptop—or your desktop.

The Power Options will vary depending on the exact hardware configuration you have. To use Power Options, the Inspiron 5100 battery must be Advanced Configuration and Power Interface (ACPI)-compliant, which dictates that all components are capable of power management. If one or more components are not capable of power management, you might not have ACPI functionality, or you might experience erratic behavior. Laptops-battery.co.uk

Power Options in Windows XP allow you to control the power management features of:

Your display

Your hard drive

Shut Down, Hibernate, and Stand by

Low battery warnings

Additionally, many laptop (as inspiron 1100 battery) manufacturers provide even greater control, giving you more components and devices, and allowing you to shut off or reduce the power consumption of specific pieces of your hardware. We can't begin to cover all the options of the various manufacturers and their power management utilities. In this column, we'll discuss how to use power management in Windows XP.

Managing Your Monitor

Power management of your display screen is something that almost everyone is used to these days. It's a good idea to shut off your display when you're not using it, even when you're running a desktop computer. Although laptop displays don't use as much power, it's still a relatively big power consumer.

Reducing Power Consumption by Your Hard Drive

The two biggest users of power on your laptop are the display and the hard drive. Windows XP lets you tell your hard drive to stop spinning when you're not actively using it, allowing you to save energy and thus battery power.

Putting Your Computer on Standby or Hibernate

There are two basic options for putting your laptop to sleep when you're not actively using it, but don't want to completely shut it down—Standby or Hibernate. Standby is energy conserving, because your entire computer switches to a low-power state. Devices, such as the monitor and hard disks, turn off and your computer uses less power. It's easy to return to work, because Standby leaves applications and files open on your desktop. Standby is perfect when you're going to be taking a break because the cabin attendant just came by with what passes for lunch on airplanes these days, and you want to quickly pick up exactly where you left off. (Note that airlines often request that you completely turn off your computer pa3384u-1brs during take off and landing. In Standby mode, your computer might appear to be turned off but it could automatically restart. So shut down your computer completely when it's not in use on an airplane.) Standby is not appropriate for long term use—on many laptops, overnight is probably pushing it on standby. And it has one important limitation—everything is in memory, not yet saved to the hard drive.

Hibernate mode writes an image of what you're currently working on to a special file on your hard drive, and then shuts your computer almost completely off. It takes a bit longer than Standby, since it needs to write to your hard drive . Hibernate also takes a bit longer to resume, since you must go through essentially the normal boot process, although in Windows XP your computer (satellite a60 battery) wakes faster from Hibernate than in previous versions of Windows. The advantage is that you can leave your laptop in Hibernate mode for days without any ill effect. When you start it back up, you'll see everything exactly as you left it. Hibernate is the perfect mode for shutting down for the night or even the weekend. Discount-laptop-battery.co.uk/

If you are using Windows XP Home Edition, or Windows XP Professional with Fast User Switching turned on, the Turn Off Computer menu will present the options to Stand By, Turn Off, or Restart your computer. To put your computer into Hibernate mode, click Start, and then click Turn off computer. Press and hold the Shift key. The label under the first button changes from Stand By to Hibernate. Click Hibernate.

Adjusting Low Battery Warnings

In Power Options for Windows XP, you can set the low laptop battery warnings for your computer. You can choose exactly how much warning you'll receive when the Dell laptop battery gets low and what actions are taken. There are two levels: Low Battery Alarm and Critical Battery Alarm. I find I like to set the Low Battery Alarm level to around 10% of remaining battery, which gives me plenty of time to finish up what I'm doing and shut down in an orderly fashion. And I don't have the Low Battery Alarm actually do anything, other than notify me. The Critical Battery Alarm, however, is set to go off at 3% remaining battery and initiates a forced hibernation. This saves my work and lets me later connect to an external power source and pick up exactly where I left off. The one caution here: Make sure you check Force standby or shutdown even if a program stops responding, as shown in Figure 1 below.

Figure 1.

Configuring Power Settings

Using Power Options in Control Panel, you can adjust any power management option that your computer's unique hardware configuration supports. Because these options may vary widely from computer to computer, the options described may differ from what you see. Power Options automatically detects what is available on your computer and shows you only the options that you can control. To configure your power settings:

Click Start, click Control Panel, click Performance and Maintenance, and then click Power Options.

Or, if you see the little latitude d800 battery indicator on your task bar, right-click it and then click Adjust Power Properties. The Power Options Properties dialog box opens, as shown in Figure 2.

Figure 2.

In the Power Options dialog box, you set options for a power scheme. Windows XP comes with several preconfigured profiles. I've shown the Normal profile for my laptop (Latitude d410 battery) here, but you can easily create custom profiles that fine tune the properties for your particular circumstances. You can create a new power scheme by clicking the time settings you want, clicking Save As, and typing a name. I've got one used for playing music CDs, for example, that shuts off the hard drive and screen almost immediately, but doesn't ever put the system into standby mode.

Enabling Hibernation Mode

Finally, if your machine doesn't have Hibernate enabled, it's easy to enable it. If your computer is set up by the manufacturer to support Hibernate: Open the Power Options Properties dialog box and click the Hibernate tab to open the page shown in Figure 3.

Figure 3.

Just click the Enable Hibernation check box and you're all set. You will, however, need enough free disk space to hold all of your memory in a single file. This means, if your laptop has 512 MB of RAM as mine does, you'll need roughly 512 MB of free disk space on drive C.

Please notice this : the tips cant used in apple laptop battery as all apple laptop are use Mac OS.

Manufacturer's Utilities

Finally, a word on the various system-specific utilities available. In general, if your laptop manufacturer includes a power management utility, it will offer additional features above and beyond what is included in Windows XP, and may actually disable the Windows XP Power Options dialog box. This makes sense, when you think about it—the computer manufacturer certainly ought to know more about the hardware and what its capabilities are, and most of them provide additional power management tuning abilities. On my laptop (PA2487U PA3107U-1BRS), for example, I can set the screen brightness from full bright to too dim to read, depending on how much power is left in the batteries. So if your laptop comes with a power management utility, you'll generally find it offers additional capabilities. Just make sure, if you have an older laptop that you've upgraded to Windows XP, that the utility is compatible with Windows XP. You may need to download a newer version from the manufacturer's Web site as I did.

Battery Performance

NOTE: For information about the Dell warranty for your computer, see the Product Information Guide or separate paper warranty document that shipped with your computer.

For optimal computer performance and to help preserve BIOS settings, operate your Dell portable computer with the main battery installed at all times. One battery is supplied as standard equipment in the battery bay.

NOTE: Because the Dell 6400 battery may not be fully charged, use the AC adapter to connect your new computer to an electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter until the battery is fully charged. To view battery charge status, click the Start button, click Control Panel, double-click Power Options, and then click the Power Meter tab.

Battery operating time varies depending on operating conditions.

NOTE: Battery operating time (the time the inspiron 1720 battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer.

Operating time is significantly reduced when you perform operations including, but not limited to, the following:

• Using optical drives
• Using wireless communications devices, PC Cards, or USB devices
• Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D games
• Running the computer in maximum performance mode.

NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD.

You can check the Dell D620 battery charge (see Checking the Battery Charge) before you insert the battery into the computer. You can also set power management options to alert you when the battery charge is low (see Configuring Power Management Settings).

CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the Dell D630 battery only with a compatible battery purchased from Dell. The battery is designed to work with your Dell computer. Do not use a battery from other computers with your computer.

CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery. See "Battery Disposal" in the Product Information Guide.

CAUTION: Misuse of the Dell D620 battery may increase the risk of fire or chemical burn. Do not puncture, incinerate, disassemble, or expose the battery to temperatures above 65 (149). Keep the battery away from children. Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury or equipment damage.

Checking the Battery Charge

The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and icon, the XPS m140 battery charge gauge, and the low-battery warning provide information on the battery charge.

Dell QuickSet Battery Meter

If Dell QuickSet is installed, press

to display the QuickSet Battery Meter. The inspiron e1705 Battery Meter displays status, battery health, charge level, and charge completion time for the battery in your computer.

Microsoft Windows Power Meter

The Windows Power Meter indicates the remaining 40D battery grip charge. To check the Power Meter, double-click the icon on the taskbar.

If the computer is connected to an electrical outlet, a icon appears.

Charge Gauge

Before you insert a DV1000 battery, press the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery has no charge.

Health Gauge

The battery operating time is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, DV2000 battery lose some charge capacity, or battery health. To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery. See Specifications for more information about the battery operating time.

NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then connect the computer to an electrical outlet, or install a second battery in the media bay. If the battery runs completely out of power, hibernate mode begins automatically.

A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The computer beeps once, indicating that minimal battery operating time remains. During that time, the speaker beeps periodically. If two DV4000 batteries are installed, the low-battery warning means that the combined charge of both batteries is approximately 90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low level. For more information about low-battery alarms, see Configuring Power Management Settings.

Conserving Battery Power

Perform the following actions to conserve battery power:

• Connect the computer to an electrical outlet when possible because battery life is largely determined by the number of times the battery is used and recharged.
• Place the computer in standby mode or hibernate mode (see Power Management Modes) when you leave the computer unattended for long periods of time.
• Use the Power Management Wizard (see Configuring Power Management Settings) to select options to optimize your computer's power usage. These options can also be set to change when you press the power button, close the display, or press Fn Esc;.

Charging the Battery

NOTE: With Dell ExpressCharge , when the computer is turned off, the AC adapter charges a completely discharged Dell 1300 battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer with the computer turned on. You can leave the battery in the computer for as long as you like. The battery's internal circuitry prevents the battery from overcharging.

NOTE: If you want to use a 9-cell inspiron 1300 battery to obtain Dell ExpressCharge, you need to use it in conjunction with a 90-W AC adapter.

When you connect the computer to an electrical outlet or install a battery while the computer is connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary, the AC adapter then charges the battery and maintains the battery charge.

If the battery is hot from being used in your computer or being in a hot environment, the battery may not charge when you connect the computer to an electrical outlet.

The Dell 6000 battery is too hot to start charging if the light flashes alternately green and orange. Disconnect the computer from the electrical outlet and allow the computer and the battery to cool to room temperature. Then connect the computer to an electrical outlet to continue charging the battery.

Replacing the Battery

CAUTION: Before performing these procedures, turn off the computer, disconnect the AC adapter from the electrical outlet and the computer, disconnect the modem from the wall connector and computer, and remove any other external cables from the computer.

CAUTION: Using an incompatible GD761 or U4873 battery may increase the risk of fire or explosion. Replace the battery only with a compatible battery purchased from Dell. The battery is designed to work with your Dell computer. Do not use a battery from other computers with your computer.

NOTICE: You must remove all external cables from the computer to avoid possible connector damage.

To remove the battery:
• If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.
• Ensure that the computer is turned off or in hibernate mode (see Hibernate Mode).Slide the two battery-bay latch releases on the bottom of the computer toward the sides of the computer until they are engaged.
• Grasp the battery by the Dell 1525 battery tab and slide the battery horizontally toward the front of the computer.
• Lift to remove the battery from the bay.

  To replace the battery, follow the removal procedure in reverse order.

  Storing a Battery

  Remove the Dell 1520 battery when you store your computer for an extended period of time. A battery discharges during prolonged storage. After a long storage period, recharge the battery fully before you use it.

New battery can not be fully charged

New battery can not be fully charged

Generally the new battery can 100% fully discharge-charge. Last month I buy a latitude d820 battery replacement, as my work dont need to take the notebook out, so I use the notebook with the AC adapter and I store the battery in my drawer. Last Friday, I want to visite my customer with my notebook and show some business projects. So I charged my battery for a whole night, but I only see my battery 70% capacity state charged next morning. My battery is really new, why it can not be 100% charged?

So I query the battery expert Jack Smith that the reason "Why new battery can not be fully charged?". He said that : after the laptop battery not use for a long time, the battery charge must in the low current in the right system power option. And then he give me some adviese to set the power Option. Now I introduce the tips for my readers step by step with detail photos.

Notebook battery Power saving techniques

Notebook battery Power saving techniques

In fact, how to make good use of Laptop battery, how to extend the laptop battery using time and life is problem for all notebook users, a problem. There are many laptop battery using tips in our daily life that we shoule know in normal use and application.

(A) quick to enter the dormant state

Do not use the notebook computer for saving latitude D820 battery power, we can set the power management program, let the system enter hibernation after a period of time, but it must wait a few minutes, is there a way to make the notebook computer system enter the sleep state immediately ?

There is a dormant easiest way in Notebook computer system : directly turn off the screen, you can make laptop to sleep immediately and effectively conserve battery power. When you need to use the laptop, only opening screen, the system will automatically return to the state before the operation.

(B) power-saving screen mode

Laptop TFT screen is the largest component of power consumption, in order to reduce power consumption, notebook computer manufacturers have devised ingenious schemes, in all the general advise are following tips: reduce the screen brightness, turn off the screen.

In some notebook power management as 40Y6795 40Y6797 40Y6799 settings to customize the brightness of the screen, the majority of notebook computers by a specific shortcut screen brightness adjustment, generally 6 to 8 level brightness adjustment.

(C) Carry out energy-saving settings

As desktop using the AC, most people may not take attention to energy-saving features, but to laptop user who must use Discount laptop battery for mobile use, the use of energy-saving features should be important. How to design computer hardware more energy-efficient, this is not a user problem. All us can do is set up the effective use of energy-saving options on the computer.

There are two energy-saving settings need to adjust the user: First, in the computer's BIOS setup program on the energy-saving mode in the settings; the most important thing is there are many in the operating system and operation of energy-saving settings. Computer system in the practical implementation of it, Windows system should take precedence over energy-saving settings in the CMOS settings.

1. BIOS settings of the energy-saving

In the CMOS settings,for example PCGA-BP2V PCGA-BP4V have a large "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and many other options. "Maximum Battery Life" is the default setting of the energy-saving mode. Notebook computer model has several energy-saving state, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode flying (sleep) mode. Notebook computer these settings, are able to regulate power consumption, mainly in the computer to enter the energy-saving state, the timely closure of the system without the use of equipment.

Such as when waiting to close the display and hard disk; dormant, apart from the display and hard drive shut down, but also can save the contents of memory to the hard disk, the basic maintenance of the entire computer system shut down state, once activated, or restart your computer, desktop will be accurately restored to pre-hibernation state. Energy Saving in the CMOS settings, set up mainly to enter the Idle Mode from Standby Mode in Standby Timeout time set by the Suspend Mode to enter the Standby Mode of the time Suspend Timeout. Notebook Phoenix BIOS of most use. Different energy-saving BIOS settings may be somewhat different, we should carefully read the screen prompts.

2. Windows in the energy-saving settings

For general users, in the Windows system management for energy conservation may be a better understanding of the operation simpler. Windows help file, in the "management hardware and software" under the entry, two notebook computers with the contents of the relevant energy-saving: "the management of energy consumption" and "the use of portable machine" in the "management of the power portable machine." Energy-saving settings in Windows, should read it.

In the Windows "Control Panel", click "Power Management", you can open the "Power Management Properties" dialog box. In the "Power Management Properties" dialog box, should be "power scheme" is set to "portable / laptop" (Using 92P1101 92P1102 08K8193 08K8192 92P1087 92P1011 battery) and reasonable arrangement "system waiting for", "close the Monitor," "turn off hard disk" option, etc. . Different computer can control the options there will be some differences, the new factory and the latest computer software will be more workable options and detailed computer settings should be based on their functions and help files for Windows.

In addition, if your notebook computer with built-infrared port, close it when not in use, you can extend notebook battery life.

Some common sense about Rechargeable battery

Some common sense about Rechargeable battery

What is the cycle life of rechargeable battery?

When a latitude D820 battery experiences a charge and discharge, we call a cycle or a period. In the stated charge and discharge principles and the capacity decline before a stated standard, the total cycles it can undergo called rechargeable battery cycle life.

What is rechargeable battery self discharge?

Primary Dell CF623 battery or full charged secondary battery, when put aside for a period, it is capacity will decline or lose, this phenomenon calls self discharge that is electricity flee away. It is decided by the inner electro-chemistry system, similar to water leakage from pond or reservoir.

What is battery inner impedance?

Battery impedance is the resistance when the current flow through an operating cell, in general the internal resistance is included both d.c. and a.c. resistance. For the rechargeable 40Y6795 battery cell resistance is small and electrode is easy to be polarized along with producing a polarization resistance while measure d.c. resistance, the accurate value can't be measured.

What is the memory effect?

Memory effect only happens on Ni-Cd batteries. As in traditional technology a Ni-Cd battery's negative is agglomeration with thick Ni crystal, if Ni-Cd batteries are recharged before they have been fully discharged, Ni crystal easily gathers to form agglomeration, which makes the primary discharge platform come into being. The HP HSTNN-LB31 battery stores the platform, which will be considered as the end of discharge for the next cycle even though the capacity decides that the battery can be discharged to a lower platform. The battery will store this process in its memory so during the next discharge, the battery only remembers this reduced capacity. Similarly any further incomplete discharge in each use will aggravate the effect makes lower capacity. The effect there are two methods to remove the effect: firstly deep discharge at trickle current (i.e. 0.1C to 0V), secondly several cycles at high currents (e.g. 1C).

What is the ambient temperature affects the battery performance?

Low temperatures (e.g. -15?) will obviously reduce Ni-Cd and Ni-MH Apple A1175 battery discharge rate. At -20? electrolyte is at its freezing point, charge speed will greatly slow down. At low temperature (under -15?) charge will raise the internal gas pressure and probably unseal the safety vent. Ambient temperature of 5?to 30? is the best range to get effective charge. Generally with temperature rising charge efficiency will become higher. But when the temperature rises to 45? or higher, the materials performance in the battery will be degenerated and battery service life will be shorten greatly.

What is the Over charge affects the battery performance?

The continual charge action after fully charged with certain charge approach is overcharge. the positive capacity is higher than the negative on design, the generated oxygen in positive can composite, through separator, with Cd generated in negative. In general condition the internal pressure will not rise obviously, but if the IBM thinkpad T43 battery charge current is so heavy or the charge time is so long, and the generated oxygen can not be used up in time, there will be some quality defect risen such as internal pressure rising, battery distortion, leakage and so on. Meanwhile its performance will decline.

What is the Over discharge affects the battery performance?

If a cell's voltage reaches a designed value, that means the battery has discharge the stored capacity, but still the discharge action is continual, over-discharge will cause. Commonly the end voltage can be identified through discharge current, for example the end voltage is set at Laptop battery 1.0V/cell as discharged at 0.2C-2C, and 0.8V/cell at 3C or more, e.g. 5C or 10C. Over discharge may cause disaster, especially at heavy current or repeated over discharge. Commonly over discharge can make cell inner pressure raise, and the reversibility of activity materials both in positive and negative will be damaged. Even by charge only part can recover and the capacity is reduced obviously.

What is the short circuit affects the battery performance?

Any kinds of conductive material being bridged with the external terminals of a battery will result in short circuit. Based on the Discount laptop batteries system, a short circuit may have serious consequences, e.g. rising electrolyte temperature or building up internal gas pressure. If the internal gas pressure value exceeds the limitation of cell cap endurances, the electrolyte will leak, which will damage battery greatly. If safe vent fails to respond, even explosion will occur. Therefore don't short circuit.
