Does anyone know if the N5270 will run on A/C with a bad battery?\n\nI've been having odd problems . . .\nThe screen goes black, and the entire machine stops responding. The only\nsolution is to force the machine to power down and reboot.\n\nI've already re-done my entire machine . . . so it's not a virus or a driver\nissue. It seems to be definitely hard-ware related.\n\nI am wondering if:\n1. I have a bad battery\nor\n2. There is something inside involving power conversion that is amiss.\n\nI do know that the machine craps out if running on just the A/C with no\nbattery after about 5 minutes.\nWith the battery in, if the A/C adapter is plugged in, it will crap out\nafter about an hour.\nWith the battery "full" and no A/C adapter plugged in . . . the machine will\nrun until it says to switch to A/C, but then goes another 20 minutes and\nthen I'm warned to switch to A/C again, it goes another 5 to 10 minutes then\ntotally dies (no power).\nUsually, after the first "warning" I plug the adapter in.\n\nAny ideas?
