I'm assuming you started with bios v3.05, and since you had to downgrade to v2.07 to apply the mod, you lost the lenovo updates from v3.05. I know lots of people are reporting this issue and (1) I don't think it has anything to do with the 7260ac card, and (2) I don't think a solution has been found yet.I bet if v3.05 were able to be modded, this issue would not occur.

arazvan2002 Posted November 28, 2014 Share Posted November 28, 2014 Why did you stopped at 2.07 since a modded 3.05 version is availble?Look what is written in the Bios modding topic:Instructions for flashing the modified BIOS v3.05:You need a USB stick prepared to run DOS, here is a guide you can follow in case you don't know how to do this:Spoiler>>> Before continuing make sure the AC adapter is connected to your laptop and your battery has at least 20% charge remaining. <<<(0) - NOTE: This step is Only necessary if your system isn't already using BIOS v3.05Update to the official v3.05 BIOS provided by Lenovo.(1) - Create a backup of your own BIOS (now v3.05) by using this tool.Extract the files and run the included .bat file from an admin command prompt..(2) - Download the files for the v3.05 mod, put the files of folder [1] to the root of your prepared USB DOS stick.Let the BiosFixer prepare your BIOS for flashing by drag and dropping your backup file on it. Put the created "v305mod.bin" file to the root of your USB DOS drive as well..(3) - Now you need to downgrade the firmware back to v2.07 in order to flash the mod..(4) - Boot from your USB DOS drive, when you see the command prompt type BIOS and hit enter. Wait until the BIOS is flashed (you can safely ignore warnings about non-existing regions)..(5) - Once the BIOS flash completed with no errors, type EC and hit enter. Wait until the EC is flashed. Then reboot. .(6) - Go to the BIOS setup menu, load the default settings, apply and reboot.Done. In case you're using an ultra bay GPU follow the instructions in post #2 and flash the vbios..NOTE: It's crucial that you flash both, BIOS and EC. Having different EC and BIOS versions can in certain situations lead to issues.IMPORTANT: If you want to go back to stock v3.05 you can do that easily by simply using the official update from Lenovo. That's it, nothing additional required in this case. Quote Link to comment Share on other sites More sharing options...
DarkLord1020 Posted December 4, 2014 Share Posted December 4, 2014 I had this same issue with Lenovo Power Management Software after updating to 8.1, even with the latest Bios update. I ended up just removing the entire suite Quote Link to comment Share on other sites More sharing options...
