Values displayed are usually calculated from values coming from the gauge chip in the laptop battery.You might want to try the same with a free different OS, no need to install anything on the harddisk. If it's the same its laptop battery causing these value jumps.
thank you for the answer! I just installed XP - same Problem. Now i will try Linux Live CD and i'll see what happens. By the way - do you know a battery calibration tool for Vostro Laptops`?
For battery calibration - known as a qualified discharge - have a look at the how laptop battery capacity is being calculated. It's an automatic feature of most laptop batteries nowadays - the conditions triggers the function also known as capacity learning.
Windows 7 has a standard function that triggers capacity learning - which is an intrusive test btw. Meaning the measurement affects the actual capacity for a bit.
i just tried Linux Live OS, but unfortunatly the problem still exists. So 3 different OS show me suddenly the same Charge Level (92%) when i unplug the AC Adapter (Load: 100%). I read the Link you posted above, but i didn't understand everything written there. Maybe the reading of the battery has to be kind of trained by the appropiate circuits? Or should i contact Dell Service again? What do you think? If it is not a serious technical problem, then i don't mind... It doesn't bother me if the battery meter shows incorrect values, but if the battery charging level REAL loses 8% (not only incorrect reading by Win7) when i unplug AC, then it's a little bit disappointing in my opinion...
