I remember when i first got my Y510p i was running into this issue anytime the wifi card was being used (connected to a network) it would not allow the laptop to sleep. I was trying a few things and ended up giving up and making sure i closed the lid as that was the only way it stayed sleeping. Then out of the blue i had walked away for a period of time and noticed when i came back the computer had gone to sleep and was acting normal. I ended up buying an SSD for the computer and swapped it out installed a fresh windows 8 install and now notice the issue has returned and since i don't know what caused it to fix it before i don't know now. I have the Intel n 7260 that came with the laptop and had did the whitelist mod to be able to install the same card you have (should be getting it next week) but now face the same problem with the computer not sleeping again. As i know since it was happening when i first got the computer it has nothing to do with the mod nor the card itself (as i think, tested another card i have in house from another laptop) and problem was still there. Once i do get the new wifi card i will start troubleshooting it again and checking what is up and will go through all the stuff i know if i do find something i will update here.

If you was to bother to go through some pages not even all you would find your answer just on the last page you find it. let alone on another thread under this category. 1. You need to find out what BIOS version you have 2. If anything higher than 3.XX then you would need to look into downgrading to 2.07 3. Yes, downgrading to 2.07 is fine and everything will still work.

Yes it's downgradable as mine came with 3.07 and just downgraded to 2.07 and modded it. As i have the GT755M SLI everything works fine after the downgrade and mod. Yes, it's encrypted according to Svl7.

It means runs the command under a admined CMD.... search CMD then right click and run as admin. Then CD (go to) to the folder with the backup.bat file is once in that dic, just type out the backup.bat file name (easy way is to just type the first letter and hit tab it will auto finish it for you). Once you hit enter it will start running some stuff and then spit a bios named file (this is your bios backup save it as if you ever want to revert back to stock you would need that) Leave the CMD open as you will need to use it again for the last step. Then open the mod tool from what ever version your bios is and just drag that bios file into the program after it's opened it will then create another file inside where the rest of the files are v1xxmod or something like that. Once it's done creating the file go back to the CMd window and Flash the modified file with the command below in the CMD window fptw64 -f v1xxMod.bin -bios Note in my case mine was v2xxmod.bin but of course just make sure the name matches the file name when typing it out in the CMD window let it do its thing wait and as posted ignore the region stuff once done reboot. Keeping either F2 or DEL once you turn on the laptop should put you into the bios screen and from there you will be able to see the Bios version.

Then how about you just buy it and check and if it doesn't work return it. Done. and you are making it sound like you are doing open heart surgery you can do more harm swapping out the card itself than doing this bios mod. If you really depend on laptop that much then you should not be doing anything period not even swapping the card since you are that scared if the laptop messes up and you are going to end up losing your job. Seriously like Svl7 said you are in the wrong thread if that's the case What do you need confirming?

Then live with the fact that you are VERY limited to crappy hardware and wont be able to use much superior hardware. Also you can revert back to stock in case of needing to send in for service. I've had my y510p for 1 month and cannot live knowing that I am locked with specific hardware. The steps on installing the modded bios are crazy easy and took me at most 5 mins to do. But hey your laptop not mine. What is the point of owning something you have no freedom with.

I would check from the bios itself and make sure what version it says when it first boots the bios. Also make sure you are creating a proper bios backup with the tool from step 1. It was simple short and sweet when i did it not sure what step you are getting caught up on leading to it report incorrect bios.

Just want to say THANK YOU very much downgraded to 2.07 from 3.05 and unlocked bios with tools on first page. Everything is working perfect, just now waiting for my AC WiFi card to arrive later on this week.

File a lawsuit? You are not forced to buy their products and once you do you are agreeing to their TOS somewhere along the lines. So a lawsuit will get you no where but wasted money.

Has anyone with 755m SLI downgraded to 2.07 and everything working? If I do downgrade and flash the modded bios will I need to do anything else as I see some ppl messing with ultrabay stuff.

Keep hitting F2 after powering on will take you to bios.

This is so ridiculous for many reasons more than one. Locking the bios?..really?...and not only that but lets bundle it with a crappy ass wifi card. Has there been any insight on getting the whitelist removed on 3.05? i really dont want to mess with anything else i do know about the whole downgrading to 2.07 but afraid it will just break something else. I currently run the SLI 755m/16gb/1tb5400rpm+24msata/intel 7260n. This wireless card is just crap period and god knows how much help lenovo tech support is. If downgrading is the only way to get the whitelist removed then i would like to see what the change list is from 2.07-->3.05. Thanks to anyone who gives help.

Was anything found on be able to remove the whitelist on 3.05?
