My computer is about 1 years old. Its has an HP EliteBook 2540p and an Intel i5. My problem is that my computer suddenly and randomly switches off on its own. There is no blue screen, no error messages, the pc just goes off as though somebody pulled the plug. The motherboard power indicator LED remains ON. It might happen anytime from within 5-10 mins of starting up, to maybe an hour or two later. Sometimes it works perfectly fine and never turns off. And once it shuts itself off, i can't power it back on. If i pull the plug and try again later or shake up the chassis a but and retry, it might boot up again and run for some random period of time before the same story repeats. sometimes i remove the beettery and restart then it going to starts.
Please help me to my issue.
