I've just received my W870 Back from "repairs". the fkers have sent me back a system that now has; Flashing Caps/NumLocks, and shuts down after about 15 seconds. I've tried removing the battery and booting up, same thing happens, shuts down after boot up. Any suggestions? I would send it back but they say, "after the new year" ARGH!! Just constant problems with this machine whether cosmetic and now this. ARGH help?
