Hi, so I have an x455l asus and I recently lost my power cable so I tried a power cable that was a little bit under the voltage rating and it did not charge. After finding my power cable I plugged it in to see that it will not stay on anymore. The charging light will turn on but it will not stay on long enough to get through bios. I have tryed taking the battery out and seeing of it can run off of ac power and that will not work. I'm affraed that I have busted the system with the low voltage cable. Any suggestions?
