Computer Would Not Wake Up or Restart
Posted on 2014-03-05
HP Pavilion P7-1154 desktop with Windows 7, with latest updates.
The system operated normally early this morning, but later my wife could not get it to wake up, nor would it restart. It was showing power (highlight light and fans running). I tried a hard shutdown (holding power button down) and it shut down. When I pressed the power button again, the light came on and the fans ran, but there was no hard drive activity and no signal to the monitor - could not access the BIOS. After several attempts, I decided to look inside. Before I opened the case I thought I'd try pulling the power plug and hit the "on" switch to drain all power, and try to restart. Lo and behold it started up normally. It took a while to come up to a steady state, but eventually all was well.
Just wondering if this is some sign of a problem that needs to be addressed before a hard failure occurs. Should I try any diagnostics?
