New battery and only charge to 45%?


My new battery cam with an eight page manual containing instructions got use in a translated (poorly) version of the Chinese original. Of course I did not need a manual to install a new battery and ran into the same problem as you. Refer to the discarded manual and find one and a half pages on how to initialize a new battery.

"User Manual on Laptop Battery

Respected users:
Thank you very much for trusting and using our laptop battery. Before using the battery, read this manual carefully. This instruction manual elaborates how to use and maintain the battery correctly. Batteries are consumables, and have a limited service life. However, we can prolong the life of the laptop battery considerably through correct operation, proper charging/discharging and correct storage.
Calibrate your laptop battery to optimize its performance
Inside the laptop battery is microprocessor software, which calculates the battery volume during the charging/discharging. Batteries must be calibrated from time to time to ensure correctness of the time and the percentage displayed on the screen. You must implement a complete cycle of charging and discharging the battery at the beginning of using the computer, and repeat this cycle every two or three months. The charging and discharging procedure is as follows:
1.Set the Power Supply option first: Right click on the screen and select Property -> Screen Saver -> Power Supply -> Power Use Scheme -> Portable. In all the subsequent operations such as When Computer and Use Battery, select Never. Under the Alert option, deselect Alert for deficient battery and Alert for serious battery shortage.
2.Disconnect the power adapter and use the battery until the computer is powered off due to exhaustion of the battery.
3.Connect the power adapter until the battery is charged to 100%. Before initial use of the computer (or resuming use of the computer after long-term storage), the battery must be charged to full.and discharged for 3-4 times to optimize the performance. The charging process takes more than five hours.
Note: When your battery is calibrated and reaches the best performance, set the Power Supply Options on your computer to the default value to ensure that the computer can send correct alerts to you, for example, low battery alert, and alert before the computer enters the hibernation status.
You must discharge the battery to let the computer power off, and then charge the battery to 100% to calibrate it. Then you can connect or disconnect the power supply anytime regardless of the status of the battery volume. Moreover, you can perform a deep charging and discharging cycle under control of the protection circuit in a time"

How to charge your laptop battery properly? During the the process of notebook...


How to charge your laptop battery properly? solarroll-laptop-solar-charger.jpg During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.
For early notebook batteries (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.
In fact the lithium batteries has a little memory effect. The lithium battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.
A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had "full" level.
Sometimes WINDOWS show that battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery
So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity . This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Armada E500 notebook Power button not responding.


Unless you took the batteries to a service center, I am dubious about your ability to confirm the main battery is holding a charge. The average lifespan of these kinds of batteries range between 3-5 years and is likely at the end of its lifespan. This would explain the diminishing performance over the last year if there were significant power or power circuit issues, they would likely be observed on AC power as well. This model of laptop requires the battery calibration utility be run in order for the laptop use the battery. In fact, the battery can show a full charge and still not function if the utility and battery have not been properly configured.. . . instructions on HOW TO do this below. If this doesn't FixYa then the battery will need to be replaced (links to replacement sources) www.BatteriesOvernight.com/HP-Batteries,----- OR --- www.new-laptop-battery.com/Compaq/?Compaq-Armada-E500-battery.htm. You will still have to run the configuration utility when you receive your new battery.
Link to Armada e500 manuals:http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01124216/c01124216.pdf
How to run config utility: Standby and hibernation must be disabled for the battery to discharge completely and shut off. To use the Battery Calibration utility, first identify whether the battery requires calibration by launching the Power Management applet as described above. On the Battery Calibration tab, all installed batteries will be displayed in the primary list box. Next to each battery name will be an indication of whether calibration is required for that battery. If calibration is necessary, the phrase “Needs Calibration” will be displayed. Select the battery to be calibrated, and click the Start Calibration button. During calibration, the utility will display an icon on the Windows System Tray to indicate that calibration is in progress. Each phase of calibration (charging or discharging) will also be displayed. Calibration is complete when the icon is no longer displayed in the System Tray. Battery calibration requires several hours for completion. If you choose to continue using the computer during the calibration process, it must be connected to AC power. The calibration process must be allowed to finish without interruption. Performing any of the following actions will prematurely terminate calibration:  Clicking the Stop Calibrating button in the Compaq Power tab.  Unplugging AC power from the computer.  Unplugging the calibrating battery. (This action may result in data loss if a second battery is not installed.)  Undocking the computer.  Pressing the power or standby button.  Powering down or suspending the machine by using the Windows menu. IMPORTANT: If the calibration process is interrupted, it cannot be resumed. You must restart the computer and start the process again.
CALIBRATING WITHOUT THE UTILITY To calibrate a battery on computers without the battery calibration utility, complete the following steps: 1. Remove the second battery, if present, so that only the battery needing calibration remains in the computer. 2. Dock the computer or connect the computer to AC power. 3. Turn on the computer. 4. Check the current battery capacity level by positioning the cursor over the battery icon in the system tray. 5. Allow the battery to charge to 100%. You may use the computer, but the recharging process will require more time. 6. Set the system to “drain” mode on the battery conservation settings by pressing Fn+F7, or select Start > Settings > Control Panel > Power (or Compaq Power in Windows NT). 7. Undock the computer or disconnect the computer from AC power. 8. Restart the computer in MS-DOS mode by clicking Start > Shut Down > Restart the Computer in MS-DOS Mode > OK. 9. Allow the computer to discharge until it shuts off. 10. Dock the computer or reconnect AC power. 11. Allow the computer to charge again to 100% as in Step 5.
