WINDOWS BATTERY METER
You will have noticed the Windows Battery Meter is very inaccurate.

Message from develoer :
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.

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.

IMPORTANT INSTRUCTION :
You May Also Need msstdfmt.dll if it`s not on your PC already.
Extract it to the /windows/system32 folder
