Toshiba Satelite L455 reboots on shutdown signal

[mohavepc]

Hello friends:
I know it has been a while since I posted but we have been very busy moving our shop.

I have a Toshiba L455-S5009 with Phoenix bios v1.30, 8Gb Memory and a 500gb Hdd. With Windows 7 home premium.

My issue is that when the machine is given the shutdown signal from the menu or the button press it powers down the boots back up. The system logs show it getting a sleep signal. This is a 3rd clean install of Windows 7 however this happens in 8.1 and 10 as well. The bios was upgraded from 1.0 to the 1.30 because of this issue before I received the laptop for repair. I have looked in the bios and can find nothing to cause this. wake on lan ect. are disabled. I have disabled reboot on error in the advanced system menu to see if it was a blue screen. I have gone to Toshiba for answers but they tell me what I am describing is impossible and yet here we are. I even sent them a video but they don't want to deal with an old yet mostly functioning laptop. This unit came with Win7 installed and it was upgraded to 8 by the customer and was fine until he tried to upgrade to 10 at which point the machine reverted half way through the process and became unstable. after completely wiping the hard drive with dban the issue persists. There is one caveat however. Linux mint 15 works flawlessly and shuts down without issue. I am stumped. anyone have an idea?

I was going to suggest a linux live test, but you beat me to it. That would seem to rule out a MB problem. Have you tried a direct shutdown /s command line? Have you tried the menu or button in Safe Mode?

I have indeed tried the menu and button in safe mode and safe mode with command prompt after running explorer. I will try running the shutdown /s command tonight when I get home. I have it there for the weekend.

It is an interesting problem. If the entire disk was DBANned post-W10, then what I'm going to suggest makes no sense, but otherwise it makes a lot of sense. The only thing I can think of is that the Win10 install/reversion messed up the W7 BCD, or superseded it with the new W10 system partition . The BCD contains GUID pointers to the shutdown, restart, sleep and hibernate functions, and it's possible the shutdown function got hosed by W10. You could rebuild the BCD using the bootrec commands in WRE.

I did a clean install of 10 using the tutorial here. Same results however, I also downgraded it to Windows 7 and the issue didn't occur until the latest updates. I believe this is an issue with the bios but I cannot put in an older bios because even with using the dos disk to update it the system diplays an error that the version installed is newer than the one intended. Even if I try to rebuild the bios with it's current version it just says not needed. I think I have had it for now :shock:
