Hi,

Yes, another post regarding a laptop shutting down after 30 minutes.

My daughter's laptop started shutting down after 30 minutes even in BIOS which made me realize that it was not a Windows problem.
This all started because I replaced the keyboard that had many broken keys - it was cheaper to buy a new one and I thought it would be faster to replace the all keyboard than the keys one by one.
After re-assembling the laptop I noticed that Windows was reporting an unknown USB device, that popped up constantly. A visit to device manager showed no errors, so I went ahead and disable USB notifications in settings.

However it started shutting down after a while. Long story short, I tested to see if even in BIOS this would happen but this time I timed it (30 minutes) and started googling for it.

A few hours later I managed to find the IME in device manager, but it was hidden and had to uninstall some of the USB devices because device manager kept refreshing. I removed IME thinking that Windows would pick it up again on reboot, but it never happened - I noted that it had version 11.0.0.1166 installed.

In Toshiba website there was an update to version 11.8.55.3510 but I was unable to install it because it says that it is not supported. I noticed also that my BIOS was outdated, so I went ahead and updated from version 1.1 to 1.9, but still IME never showed up again, nor it allowed me to install IME/AMT drivers.

More googling and here I am. After reading a few posts I think that I need to run MEInfo and fpt, so, if someone can take a look at it and advise on how to proceed.





Thank you very much for your time.

Cheers,

João

Hi plutomaniac,

Thank you very much for your answer.
I have been searching a little more and found this post at (sorry cannot post links) https:// www win-raid.com/t2133f16-Solved-How-to-unlock-Toshiba-P-A-Z-BIOS-options.html that made me think is possible for me to follow the https:// www win-raid.com/t3553f39-Guide-Unlock-Intel-Flash-Descriptor-Read-Write-Access-Permissions-for-SPI-Servicing.html as you suggested and I probably can use E6 option.

So I downloaded and extracted BIOS v1.9 from https:// support.dynabook.com/support/viewContentDetail?contentId=4006571, followed all the steps and got this:

0x3AC36 			One Of: Me FW Image Re-Flash, VarStoreInfo (VarOffset/VarName): 0x3BB, VarStore: 0x1, QuestionId: 0xD8, Size: 1, Min: 0x0, Max 0x0, Step: 0x0 {05 A6 E2 06 E3 06 D8 00 01 00 BB 03 10 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
0x3AC5C 				One Of Option: Disabled, Value (8 bit): 0x0 (default) {09 0E 04 00 30 00 00 00 00 00 00 00 00 00}
0x3AC6A 				One Of Option: Enabled, Value (8 bit): 0x1 {09 0E 03 00 00 00 01 00 00 00 00 00 00 00}
 

As for E6 steps I now need to run

setup_var 0x3BB 0x01
 

or

setup_var 0x3BB 0x1
 

?


Now, can you please explain, when you say at Note 1 of E6 Guide,

Zitat

---

not recommended unless you can recover from NVRAM corruption

---

and

Zitat

---

The BIOS may refuse to boot if an unsanctioned NVRAM modification is detected, thus leaving the user with a soft-brick.

---

what are steps to recover from it, so that I can look before messing with this.

Also, if I decide to go ahead with this, which guide should I follow next?

Thank you again for your time.

Hi,

Thank you for the files. I have been investigating this a little further and I am ordering a programmer just in case. If one of the methods fails, maybe I can with the other.
I'll report back as soon as I try the procedure.
