Question:

Dell Vostro PC won't turn on if power cable left in overnight. Why is this, and how do I fix?

At the end of every work day I shut it down in the normal way (through the Start Menu) and then every morning I return to it and it won't turn on no matter how many times I press the on button or if I hold it down.The only way I can get the computer to turn back on is to remove the power cable for 10 minutes and then put it back in and hold the on button for about 10 seconds. This is a bit of a pain but also quite worrying as the computer is new.I wonder if my computer is broken or if this is an intentional feature. If so how do I turn it off?It might help to know that even when I have shut it down there is an LED on the back that stays on. In fact it stays on for 5 minutes even if I take the power cable out!I have a Dell Vostro 260S PC. It runs Windows 7 64-bit and the processor is an Intel i3Please help techies.

Answer:

It really sounds like a hardware problem, you shouldn't have to unplug from the power supply and plug it back in after ten minutes to get the pc to power on, swap out the power supply and the power cable that hooks to it , also make sure the power cable 24pin cable is in the motherboad good and tight and the option cable 4-8 pin is hook to the motherboard a connector above the cpu if the motherboard has one.
This sounds like a bad shutdown. Are you sure it's shutting down and not hibernating or sleeping? As it's new, you should call Dell, but you can try this. Close all your programs and shut it down by holding the power button in until it's off (Just 5-6 seconds.) See if it starts up after that. Edit:What happens if you try shutting down with the On/Off switch?
