"Why won't my Samsung Galaxy Tab 2 charge?"に関する回答All, I tried all of the suggestions on this thread...halfway connecting, wiggling the connector, pressing buttons, etc. I used contact cleaner to clean the USB side and the Samsung side. I used a toothpick to clean the contacts. Nothing. just a single blue stripe on the battery icon and then a reset. I just brought it to the local Best Buy and the Samsung reps plugged it into her power supply and voila! It worked. I was never happier to see multiple blue stripes before. A trip to the local MicroCenter and I have a new cord ($6.99) and a working Tab 2.
