"Why won't my Samsung Galaxy Tab 2 charge?"に関する回答I had the same problem with the red x and tried everything I could find in the forums.. All efforts failed. The tablet drained so low that it would not power on at all. Battery icon flashed one bar only. I left it off but plugged into the charger for a coupla days. Meanwhile, on another computer, i ordered a new power cord/charger for $8 that came in 3 days. It slowly recovered to 17%, enough to power on. Plugged that sucker in and Voila! the red X was gone and the lightning bolt indicating proper charging was restored. This tells me that the frail little cord was damaged and inadequate to do the job sufficiently, but not totally shot. It has been working like new since then.
