6. For laptops that work as Hp PB992A battery Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.


7. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.


Battery-saving sleep modes: Should I use Stand By or Hibernate


Standby mode

Use standby to Hp PB994A battery save power when you will be away from the computer for a short time while working - your monitor and hard disks turn off, all applications and open files are stored in RAM. When you want to use the computer again, it comes out of standby quickly, and your desktop is restored exactly as you left it.


Hibernation Mode

Use hibernation to save power when you will be away from the computer for an extended time while working - your computer shuts down to save power but first saves everything in memory on your hard disk. When you restart the computer, your desktop is restored exactly as you left it.


When you choose Start, Turn Off Computer in Windows XP, your options are Stand By, Hp PB991A battery Turn Off, and Restart. To Hibernate, place the cursor over Stand By, then hold down Shift and click.

Basic Tweak

Basic Tweak

If you own a recent ATI or nVidia graphics card, then you have access to a basic clock tweaking feature. Go to the Control Panel, access the Display, choose the Appearance tab, and click on Advanced Settings. Depending on the model Toshiba Laptop Battery of your graphics card, there may be automatic clock reducing features. Look for names such as POWERPLAY and configure appropriately (set to Max Battery when not using 3D graphics).

Disabling Components

There are many components on your laptop that are rarely used. However, the components are still on standby, wasting precious power. Disabling unused components is a great way to save power.


To disable a component, right click on "My Computer" and select "Hardware." Then, click on the "Device Manager" button. This will access the Device Manger, which lists all the components in your laptop. You can now disable any component at your leisure by finding the component of choice, right-clicking on it, and selecting "Disable."

Possible devices to consider disabling or disconnecting:

Wireless (some laptops have a on/off switch)

Bluetooth

USB

Firewire (IEEE 1394)

Modem

Serial/Printer/VGA/SCSI ports

Infrared device

CD-ROM/RW or DVD-ROM/RW drive

Memory card

LAN

Sound

Remember that after Toshiba Satellite 2100 Battery disabling these components, you will need to re-enable them the same way to be able to use them again.

Additional methods


Decrease LCD brightness

Another method in maximizing battery life is setting the screen brightness.'Dim the LCD screen to the lowest comfortable level to achieve maximum battery life. If you're going to watch a DVD movie, set the brightness to its lowest if the lights in the surrounding room are off.


Standby/Hibernate

Place your computer on Standby as often as possible. When you are not using your computer for a while, place your computer into Hibernate; and when you are not using it for the time being, shut down your computer.

You can recover the previous work state of your computer faster when your computer is in Hibernate than when it is shut down. If your computer is on Standby, it takes a much shorter time to recover the work state as compared with Sony PCG-Z505 battery

recovery from Hibernate.


Disabling Processes


Running many unnecessary programs will cause your CPU to run harder, and thus use more energy. Therefore, removing any unecessary processes to save battery power.


Spyware/Virii/Hackers

Spyware and virii are destructive programs that can cause your CPU to work for them, and should be removed at once. Hackers can put virii and other malicious programs on your laptop as well, causing your CPU to work more often. Sony PCG-V505 battery Even if battery life is not a problem, it is always good to maintain a secure laptop.


Be sure to keep your virus scanner updated at all times.


AVG Antivirus is a great FREE antivirus scanner.


Spybot S&D, as well as Ad-aware, are great FREE anti-spyware programs. Download both, since they are not all 100% effective.


Using a firewall can prevent hackers from accessing your laptop, and should be active at all times. Windows has a built-in firewall (Windows XP SP2 and above) that works fine. ZoneAlarm is a great FREE firewall, better than the built-in Windows firewall.


Keeping Windows updated through patches is always a good idea to prevent hacker attacks. A common way for hackers to access your computer is through Internet Explorer. Even the latest patched version still has security "holes." Download Firefox, the Sony PCG-R505 battery best FREE web browser, to alleviate these problems.


Unnecessary Startup Processes

Laptops bought from companies such as Dell, Compaq, Gateway, Emachines, IBM, etc, have many'unnecessary startup programs. Disabling these programs not only saves battery life, but also saves precious RAM. By removing these programs from the startup repretoire, you also have the advantage of having a faster startup time.

First, select "Run..." in the Start menu.

Then, input "msconfig" into the field

Access the "Startup" tab, and take a look at the programs you have starting up. Disable'everything that you don't need. Examples of programs that you need include:


ATI Tool (from the Laptop Underclock/Undervolt guide)

RM Clock (from the Laptop Underclock/Undervolt guide)

ctfmon

MSN/Yahoo/Trillian

Misc. hardware programs, eg for a HP printer

Virus scan

Experiment! Another good idea is to Sony VGP-BPS10 battery, disable everything, then take a look at what's missing that you need, find the program that you need (take a look at the Command - it shows where the program is located), and enable it. Then, repeat. If you don't know what a program is, you should probably disable it

Next, click on the "Services" tab. Check the "Hide All Microsoft Services" tab. Although you can disable many Microsoft services to further increase performance, we are not going to cover it. You can search on the internet for guides that will help you with this. It's a lot more difficult, and the results are different for each person.


Again, do as you did for the Startup tab. Keep everything that you think you might need. Be sure to keep your Antivirus scanner service. Many program services are just to aid in load times, or other trivial tasks. Disable them, then test the program to see if it still works.

The Basic CPU Tweak

The Basic CPU Tweak


Laptop Battery Optimization Guide (Basic)


This tweak will enable th eToshiba Satellite A65 Series Battery basic, built-in power-saving function in your CPU. Go to your Control Panel, and select 'Power Options". There are 3 settings that matter to you:


Home/Office Desk - This setting will disable'the power-saving features for your CPU only when the notebook is plugged in the AC adapter. When Home/Office Desk is set while running the battery, the CPU can still throttle down.


Portable/Laptop - This will enable PowerNow!, Cool&Quiet, or SpeedStep, if your CPU supports it. These technologies all clock down your CPU when not in use, thus saving you battery life while maintaining similar performance.


Max Battery - This setting is only useful when you are really desperate for battery life. By switching to this profile, the CPU will be set to the lowest setting, which should be around 600Mhz to 800MHz. This will severely hinder performance when needed, though.

Additional settings mentioned below will also improve your battery life.Toshiba Satellite 1900 Battery By setting the monitor or hard drive to turn off when not in use, you can also save battery power. Be sure to modify only the 'Running On Batteries' column.


Turn Off Monitor - This setting will turn off your monitor when not in use. Only turn this on if you won't need to look at your screen, eg if you're gone from the keyboard, or if you're only listening to music. However, if you are watching a movie, the monitor will still turn off after the allotted time has passed, making this a potentially annoying feature.


Turn Off Hard Disks - This setting turns off your hard drive(s) when not in use after the allotted time. This is rather useful, because many programs, when running, do not actually access the hard drive. However, setting it too low will prove an annoyance, because it takes a while for the hard drive to go from off to on.


System Standby - Again, like the previous settings, this will make your system go Toshiba Satellite A60-662 Battery, into Standby mode after the allotted time has passed. This is only useful if you'll be gone from the keyboard.


GPU Tweaks


Tweaking the Graphics Card

When performing basic 2D tasks, such as web browsing or other tasks, the speed/quality of the graphics card makes no difference. Therefore, it is in your best interest to turn down the power of the graphics card to increase battery life. The most effective way to accomplish this is to lower the clock speed of the graphics card core and memory. If you have integrated graphics, you have limited access, and can not perform ANY of the following tweaks.


Before you get started, you should find out what card you have by going to Control Panel -> Display -> Settings
