Battery preparationBefore you begin you must fully charge the battery. Do this by leaving the battery charging from its own AC adaptor.
Note: If the battery has already had a full charge - discharge - charge cycle in the last month, then you do not need to do this again.
Check the following:
Check the computer is indicating that it is receiving a charge (normally a flashing LED).Ensure that the AC adaptor you are using is the correct one. Each AC adaptor is normally labelled with the same serial number as the computer it came with.Ensure the mains supply is from a known good supply (e.g. use a power socket that is known to be working and is on all the time). In particular, do not use a mains supply in a 'charging trolley' or NoteBus as this may be the cause of the issue.Do not apply any pressure to the power plug, such as resting the computer on the low voltage DC power plug or allowing the AC adaptor to hang from this plug. This can cause poor contact and can damage the power socket inside the computer.
Testing procedure using BatCal (if BatteryMon test cannot be run)If using an RM Window Box system, log on as Manager. If using a Community Connect system you will need to log on as someone who has sufficient rights to use Control Panel and run applications.
Download the RM BatCal utility from the Download section below)to the Microsoft? Windows? desktop. This will help you test the battery. Follow the steps below to continue:

Remove the battery from each computer and label it with the serial number of the computer. This is to ensure your warranty is valid, in case you need to return the computer for a warranty repair or battery replacement. For a valid warranty claim, the battery serial number must match RM factory records.Connect the AC adaptor so that the computer is working from the mains supply.Remove any PC cards (PCMCIA cards), USB devices and other peripherals.Disable the internal wireless card, if fitted (usually by means of a switch on the notebook). Wireless operation can reduce battery discharge times by up to 20%. (RM quoted battery life does not include wireless use).Disable any screensaver (so that you can always watch the screen).Run the BatCal program.Click on the Set Slow Discharge button - ensure that Slow Discharge is displayed in bold just below the View Result button.Click on the Begin Calibration button. The Control Panel - Power Options Properties dialog box will be displayed.Follow the instructions displayed in the BatCal window, e.g. turn all battery power settings to Never and set the power scheme to Portable/Laptop. If you have very poor battery life, you can also de-activate the Alarms settings, so that the computer does not shut down when it reaches a critical level.
This is because an uncalibrated battery can lie about its capacity and cause the notebook to hibernate when it is not actually empty.Click on OK to close down the Control Panel applet.Click on the BatCal pop-up dialog box that prompted you to set up the Control Panel settings.Click on Yes, when asked if you are ready to start the run.Remove the AC adaptor plug as prompted by the BatCal utility (normally the screen will dim). If your computer has been manually set to a high brightness level when running on battery you should set this to a medium level. High screen brightness will draw more power (e.g. five percent more) than a medium level of brightness.BatCal should now begin to log the battery charge.Leave the computer alone - do not close the lid.
