windows 7 computer turns on after hibernate

Currently your many answers are only try this and do that. The value and behavior of those numbers says so much about what the power controller sees and is doing. To say more starts by measuring some key voltages on six wires. Possible that Windows was confused by some new design or some defect and loaded wrong software into the abstraction layer. Then install unique software in a hardware abstraction layer to customize Windows for that unque type of hardware. Windows must determine which hardware exists. Remember, most computer hardware is different. Inputs include and are not limited to front panel switch, power supply status, BIOS contoled settings, some AC line anomalies, 5VSB, temperature, fan operation, and those wakeup features.Ĭurious is a problem that only occurred with the Windows 7 to Windows 8 upgrade. This power controller takes all those inputs and many others to determine if a system can power on, when the CPU can execute, and when power is removed. So outside of a new motherboard, is there a fix? Besides this rebooting, I haven't encountered any other issues.Ĭlick to expand.All those recommendations are inputs to one device that determines when power goes on or off. Because even now, unplugged, it still seems to reboot. It all seemed to be functional and worked as intended, the monitors were the last thing to replace and that just seemed to trigger it but maybe its something else. Everything swapped out except motherboard and CPU.

I pretty much completely rebuilt my computer over the holiday season. When I go to shutdown it will turn off but then it starts making noises as if trying to power back on, sometimes its seems to succeed and it boots up, sometimes it seems to fail and everything powers off. I have done it at least 8 times and it seems to still power back on but not EVERY time. I continually tested it by powering it on then shutting it down, repeat. I unplugged both the USB cables from the computer. Sorry, I had to go to work so I wasn't able to respond on this.
