I was in Windows XP with the Google Chrome browser on my display unexpectedly gone black and the system stopped responding. A wireless mouse connected to a USB port on the back will go out. I tried, unsuccessfully, to make the computer respond, but gave up and forced the closure. When I tried to turn the computer back in thirty seconds later, the hard drive and CD-ROM indicator on, but the screen remained the CD-ROM black. The light was flashing rhythmically. After one or two seconds, the battery light turned orange. After being for about ten seconds, the hard disk and CD-ROM lights suddenly closed, and after a second battery driver off too. At no time did any of the three lights in the upper left corner of the laptop instead.
