Danke!
Bis auf die Akkuanzeige funktioniert der Rest problemlos.
Muss ich eben mit diesem kleinen Manko leben.
 

Es gibt auch keine Vista-Treiber für deinen Laptop.
Sonst hätte ich vorgeschlagen, diesen zu versuchen.
Aber wenn es nur die fehlende Akku-Anzeige ist: damit kann man leben, man kennt ja die ungefähre Laufzeit...  

Ich denke auch, das ist zu verschmerzen.
Mich wundert bei dem alten Teil sowieso, dass alles andere geht. Aber für meine Zwecke reicht das Ding noch.
Vielen Dank nochmal für die schnelle Auskunft!!!
