A Little Black thing fell out of my Lenovo G51's charging port. I was able to manuver it back in with the plug, but a few hours later, it bacame loose again. Repeat for a day or so. Eventually, the little black thingy fell out while I wasn't paying attention. My charger port worked for an hour or so after that, but soon screwed up. Now, my Laptop won't charge, is at 0%, AND won't give me the "Low Battery" Light flash when i press power. I did the press 10 times in 10 seconds and hold for 30 thing, and my PC still won't respond. My best geuss is that the little black thing was the adapter to lock the prongs in place, and that without it the prongs got bent. Oh, by the why, my charger is hideously screwed up.
