it happened randomly if i just plugin HDMI Display & keyboard & wireless mouse. if it's following some certain event, i must notice it since this issue existed half one year.

the original power adapter lost, so today i found another adapter of 19V 4.22A output which using on a Fujitus's notebook. after plugin this new adapter, i plugin RJ45 & HDMI display & keyboad & wireless mouse, and then play lossless music with foobar, XP halt again after several seconds. if i just play internet radio with another software with max ratio of 128kpbs, XP halt less frequently than playing lossless music file with foobar.

my new testing is, just plugin HDMI display & keyboard & mouse, and use this dock normally and see what's happening. after one or two day i'll report my testing again.

THX!

Sorry for such long time to feedback.

After plugin enough power, there is no freezing at beginning 2 days, but after then, it froze 1 or 2 times one day, but better than before changing power. So I send it back to seller and no more using.

Thanks to all you reply me!
