I have an 8740w elitebook running Windows 7 Ultimate 32-bit OS that completely shuts off intermittently. Sometimes, it powers off and reboots on its own. Other times, I have to actually press the power button for it to come back on. Once it's back on, I can go hours without it happening again or it can happen in as little as 5 minutes. It seems to happen most frequently when I'm streaming video, but it has happened at other time
I have updated every piece of hardware on the device, including the video and BIOS, with the most recent available drivers available. Intermittent issues are the toughest ones to diagnose, but I really have no idea why this is happening.
Any suggestions are definitely appreciated.
