Computer not powering down after shutdown OS
Posted on 2014-10-08
I repaired some days ago a sony vaio with hard disk broken, I changed the hard disk and installed a new windows 7 and I noticed that when I select shut down, Window 7 is going through the process of shutting down but the pc just doesn't cut the power off to the motherboard, fans, they are still going and power light is still on. I can only complete the shutdown by holding down the power button for a few seconds. I phoned to Sony and they told me that 1.- The disk was not homologated for Sony and 2.- The system wasn't the original W7 home supplied with the laptop. So they could not help to me. (Really I understood why sony has ended the sale of laptop).
I tried with W7 W8 and linux and in all the systems the issue was the same....So I thought something in the power supply was damaged.
This morning I was preparing a new computer an Asus all-in-one with w7, I have installed all the system and updates. As it was a bit slow, I made a backup with acorns, changed the disk for a SSD disk and restore the system to the new disk.
And my surprise is that when Window did shut down (my screen gone blank, mouse and keyboard are inactive) but when I try to shut down the computer, power led is still on, the pc did not seem to be powered off unless I hold down the power button for a few second. The some issue than the Sony Vaio.
In both cases I changed the disk but in the Sony I used a mechanical disk and in the Asus a SSD disk.
Somebody can help me?
