This is my daughters computer and awhile back the battery stopped charging. She told me that when she would start it a message would come up asking her to press enter to continue. She got in the habit of hitting enter so one time she hit enter before she was asked and the screen went black but the computer stayed on. After awhile she unplugged the power supply to stop the hard drive from running. Since then the computer has not turned on at all. Can I save her computer or has it seen it's last?
