Re: Remove_SMM... UEFI.
Hello the team !
i have a Lenovo Thinkpad T460 of a friend with startup password locked. No boot in windows.
( MB Lenovo NM-A581 REV 3.0 )
Error messages :
0271 : Check Date and Time settings
---> i have tried to remove CMOS Battery
0183 : Bad CRC of Security Settings in EFI variable.
---> EEPROM seems to be corrupted
Press F1 to enter Setup.
---> and then ask for startup password ( supervisor password is also configured)
no access anymore to the UEFI Bios.
It is possible to recover with dump EEPROM and then patch it ?
( it's an Winbond 25Q128FV )
Thanks for your advices.
Dave

by DynaxSCHi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.
For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... .

by CronaxFDHey guys,
Bought myself Surface Pro 4 tablet today on a local craigslist-type website.
I've seen that UEFI was password protected and of course the seller forgot the password, but decided to buy it anyway.
Really needed such a tablet to use with RomRaider to do some logging/tuning on my car.
It has secure boot turned off and boots from USB, so I've formatted SSD and have done clean win10 install.
Works fine, but wanted to ask, are there any real security risks associated with UEFI settings on Surface (remote access etc.)?
From what I've... -
by S70rm7r00p3rHi guys.
I am very new to this business and i have some questions. Maybe someone can help me further.
I have a 2015 Intel NUC NUC6i3SYH and for some internet and office the computer works perfectly. Lately it has been bugging me a bit on and off. Then I saw there is a UEFI update from Intel and I thought if I put it on, the problems might be gone, but unfortunately the update didn't go through. The screen stayed black and after waiting for a while nothing happened, I had to pull the plug at some point. Of course, the NUC then failed to boot!
