I have a friend who has been experiencing a periodic shutdown of his Toshiba laptop which started when he was doing video editing. Now, the laptop powers down everytime after about 5 or 10 minutes of use. He has checked the battery of the laptop and it is fully charged. The laptop itself is about 3 years old and he is also running Windows XP on it.
Any suggestions for correcting the problem will be appreciated. I look forward to hearing from everyone regarding this question.
