Dell Vostro Reboots instead of Shutdowns

Interesting enough, it never seems to amaze me how much nothing changes. Over the years I have run into enough hair pulling experiences with laptops that can fill at least a small volume. Anyway, in this situation I was on a goal to reinstall Windows 7 Professional on three Dell Vostro laptops. As we know if have been doing this for a while, the OEMs often put an OEM partition on their products. These partitions usually can be removed if you reinstall the OS without using their recovery procedure. I have done this many times.

In this case I installed the OS on all three laptops. When I did the first one, I left the OEM partition because at first I did not think to wipe it. After the OS was installed I went back and deleted it with Diskpart. All was OK but for a small un-formatted partition at the beginning of the drive.

When I did the second two, I thought delete it while installing and you will not have to do it later. Well, I don't know why it happened, and I don't know if it is why it happened, but after I was done I noticed that these two never shutdown no matter what: Shutdown button, power switch, or command. They just restarted automatically.

My solution was more of a gut feeling from dealing with these goofy problems. What I did was download the BIOS utility and re-flashed the BIOS. Now the BIOS was the same rev; but it worked.

Why did I think of re-flashing? It came from so many times, sometimes in the dead of night with failing servers and PCs where magically a BIOS or Firmware update fixed the strangest problems and resurrected dead machines. Might not always work, but it has more often than not.

Hey, just wanted to say thanks for your post. Our support team was baffled about the exact same issue on a Vostro 1450 and re-flashing the BIOS with the exact same version fixed the problem! The shutdown-turned-restart issue seemed to have started after a serious of Windows Updates... so I'm not sure how it happened but windows updates seem to have put the system in an undesirable state.
