WINDOWS XP BATTERY METER

WINDOWS BATTERY METER

• You will have noticed the Windows Battery Meter is very inaccurate. The reason is the
• Battery in the Eeepc is a DUMB Battery and doesn't supply accurate information.
•  
• I have written my Own battery Meter and it is quite accurate.
•  
• Download My Battery Meter

• The Battery information supplied by the ACPI in the Eeepc is total crap. No wonder Asus can't get a decent battery meter. 
• The main problem is the Battery is NOT a Smart Battery. That is why its so difficult to get an accurate battery meter.
•  
• I have done mine the same way as ASUS. It must be calculated from the Battery Voltage as that is all the ACPI supplies.
• Since its a Dumb Battery their is no other correct information available. The way I have done it to get quite an accurate status
• was to Profile each battery I had using the same conditions. I profiled them using %100 CPU usage and normal screen brightness 
• with WiFi on.
•  
• The program has built in Profiles for these batteries.
• ---------------------------------------------------
• ASUS 7.4v 4400 mAH
• ASUS 7.4v 5200 mAH
• ASUS 7.2v 5800 mAH
• Mugen 7.4v 7800 mAH
• Mono Mobile 7.4v 10400 mAH
•  
• Their is also an option to create a CUSTOM Profile. The Program has instructions on creating a custom battery profile.
•  
• When you run the program the first time you need to Select the Profile for the Battery you are using.
•  
• Their is no Auto Install program. Just Unzip the file into a folder called BatStats. Create a Desktop Shortcut and also Create a 
• Shortcut in the STARTUP group if you want it to run when Windows Boots.
•  
• You also need to DISSABLE the Windows Battery Power Alarms. This program has its own alarms you can set. You can set Alarm 
• between 20-60 Minutes Remaining and Shutdown windows between 5-15 Minutes remaining.
•  
• The program sits in the Status area, If you mouse over it the Percent and Time remaining will be displayed. Double Click to open or 
• Right click for menu.
•  
• The Percent left is accurate to 1 Percent. Minutes left is accurate to 1 Min.
•  
• The Battery Voltage is sampled every 6 seconds and the Percent and Time Remaining are updated every 30 Seconds.
•  
• You will notice the Mono Mobile does not meet it's specifications. All other batteries tested met their Specs. The Mono Mobile only
• manages about 8900 mAh
•  
• Please give my program a try and see what you think. It is about as accurate as is possible when using a Dumb Battery.
