Armada E500 notebook Power button not responding.

\015 Armada E500 notebook power button and sleep button not working. It won't start on battery but starts immediately on AC power if the battery is unplugged and AC plugged in. Suspect hardware problem as the symptom was getting worse over the last year. Is there any circuit available for the power control board?The BIOS and main batteries both test OK and charge OK.\015

Answers :

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.\012

\012How to run config utility: \012Standby 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\012launching the Power Management applet as described above. On the Battery Calibration tab, all\012installed batteries will be displayed in the primary list box. Next to each battery name will be an\012indication of whether calibration is required for that battery. If calibration is necessary, the phrase\012“Needs Calibration” will be displayed. Select the battery to be calibrated, and click the Start\012Calibration button. During calibration, the utility will display an icon on the Windows System Tray to indicate that\012calibration is in progress. Each phase of calibration (charging or discharging) will also be\012displayed. Calibration is complete when the icon is no longer displayed in the System Tray.\012Battery calibration requires several hours for completion. If you choose to continue using the\012computer during the calibration process, it must be connected to AC power.\012The calibration process must be allowed to finish without interruption. Performing any of the\012following actions will prematurely terminate calibration:\012\001 Clicking the Stop Calibrating button in the Compaq Power tab.\012\001 Unplugging AC power from the computer.\012\001 Unplugging the calibrating battery. (This action may result in data loss if a second battery is\012not installed.)\012\001 Undocking the computer.\012\001 Pressing the power or standby button.\012\001 Powering down or suspending the machine by using the Windows menu.\012IMPORTANT: If the calibration process is interrupted, it cannot be resumed. You must\012restart the computer and start the process again.\012
\012\012CALIBRATING WITHOUT THE UTILITY\012To calibrate a battery on computers without the battery calibration utility, complete the following\012steps:\0121. Remove the second battery, if present, so that only the battery needing calibration remains in\012the computer.\0122. Dock the computer or connect the computer to AC power.\0123. Turn on the computer.\0124. Check the current battery capacity level by positioning the cursor over the battery icon in the\012system tray.\0125. Allow the battery to charge to 100%. You may use the computer, but the recharging process\012will require more time.\0126. Set the system to “drain” mode on the battery conservation settings by pressing Fn+F7, or\012select Start > Settings > Control Panel > Power (or Compaq Power in Windows NT).\0127. Undock the computer or disconnect the computer from AC power.\0128. Restart the computer in MS-DOS mode by clicking Start > Shut Down > Restart the\012Computer in MS-DOS Mode > OK.\0129. Allow the computer to discharge until it shuts off.\01210. Dock the computer or reconnect AC power.\01211. Allow the computer to charge again to 100% as in Step 5.\012
