Well i know that the Uniwill has the same problem 223II0 same model~ all you have to do is change in ur Bios the disable battery saving mode and it'll stop blinking. Just set up battery saving mode on XP and not directly in ur BIOS
for all those who don't know about this brand just go to the notebook general section and search for Uniwill 223II0 or even Uniwill you will know alot about it very quickly and a growing reputable brand~
