HP PC fix by removing/replacing cables???

I recently purchased an HP e9280t Desktop PC. A problem occurred today that the fix has me puzzled and am hopeful someone in this forum can clarify as to why it worked. I could not reboot, Windows logo would appear then go to a blank screen. It would reboot in safe mode with no problems. I removed all software I had added to the startup menu and rebooted but it still wouldn't work. In recovery mode I selected the basic diagnostic tool and everything checked out. I finally called HP tech support. They had me disconnect all cables to my pc, depress the power button for 20 seconds to dispell any power remaining in the pc. Without doing anything else, they had me reconnect everything and do a reboot. It worked. I asked the tech rep how that would fix the problem and his answer was possibly static electricity caused the problem and what I did released the static electricity allowing the system to recover.

I am not technical and would sure appreciate any comments you have have as to what may have been the problem and if this problem will resurface, in your opinion. His explanation didn't make sense to me but then I am not technical and his english was a litte problematic.

I will appreciate any comments/suggestions you may have.

Thank you...............Ralph

I think, that resets it/something too.

He probably meant stored electricity...not static electricity.....

The stored energy was preventing the re-set.

An example would be removing the CMOS battery on a desktop machine to re-set the BIOS back to defaults...if there is enough stored energy in the machine i'm told the re-set won't take place...

Thank you. Talking to those overseas tech reps is challenging, not their fault but it is difficult. I appreciate your input..............Ralph

I've had to do that to reset the overload protection circuit for my motherboards USB bus. Even with your PC turned off there is still power supplied by the auxiliary +5V supply in the power supply. It supplies the power to turn the PC on and may even power your USB ports and PS2 ports. It does on mine and I can turn my PC on by hitting the space bar on my keyboard or clicking a mouse button. You have to turn off the AC feeding the power supply to turn off the aux 5v supply. Pushing the power button just drains any voltage stored in capacitors in the power supply. It will drain off buy itself in a couple of minutes, pushing the power button just turns that into a couple of seconds.

Thanks for your response. I really appreciate it. I have found another problem that is related and will start a new post later today. It is very puzzling and frustrating since it is a new PC.

Thanks again................Ralph
