Hey svl7, sorry to bother you. I'm really interested in bios unlocking, as I have a similar Lenvo model (G570), and the bios limits are very annoying (Basically, I can only change the date). Do you think I can unlock it's bios? Is it hard to do by myself?

My bios is: InsideH2O Version 03.60.4240CN33WW(V2.19)

It has the lastest update. My OS is Win 7 SP1 64bits

Heres a link to the bios update if you want to check it out:

Thanks for the help!

i created backup (Create a backup of your own BIOS by using this tool.

The archive contains the files of the program and a .bat file that will create a backup of your BIOS. You need to call the .bat file from an admin command prompt.)

now i want to go back v2.07-> v3.05 (from backup) but EC version still keeps 2.07

borrowed picture from 1st page.

v3.05 -> 2.07

Hi

I used this on my computer with 3.05 BIOS

First you should go to this post and download the tool to backup your bios as they are now. Before doing any mod installation. After you have made a backup file save that file some were that you can remember it because your Windows key is in it.

Then download the downgrade file from this post and downgrade to 2.07 BIOS.

Then make another backup of the new 2.07 BIOS and then use the BIOS fixer from the first post again to install the mod to it.

Then you flash the new bios you just made, as they say in the first post.

Don´t forget to follow the instructions on these posts. This worked great for me and had no problems.

Many thanks to svl7 for making this possible!

I have question how can i go back to my original bios(backed up it first) ??

Hi everybody! Is there a way to mode Ultrabay gpu G750 bios for a better cooling I mean to set up maximal cooler rpm like it spins when dust removal is on. Because now its running at 50 or 70%. Thanks!

For anyone looking for a whitelist fix who may have come across the claim that the list applies only to the WLAN slot and not a secondary mini PCI, as I did on a couple pages, let me verify this for you:

Connecting a wifi card to the second mini PCI slot in the Y500 does not work. The card is simply not recognized at all. You will require the modified BIOS which removes the whitelist requirement.

There was something about fan in unlocked bios but i havent examined it yet.

So, now running unlocked 1.09 bios and sli-gpus unlocked too. Got my temps down quite easy:

1. From Intel Xtreme Tuning utility, undervoltage CPU -100mv, and frequencys set 4 cores 2,9ghz, 3 cores 3,0, 2 3,1ghz and 1 3,0ghz

2. For both the gpus, nvidiainspector is the answer. :) lower the max. temp from 96'c to 80'c. And with overclock you can compensate that temp (and clock) lowering thing. So i got gpu boost 150mhz and memory 200mhz. Gpu stays below 80'c because of undervoltage.

Sorry my bad english....

You are at the right place. The Y510p (and Y410P) have "locked" bios so it doesn't allow such a change. You new to "flash" a new unlocked bios for this. So read this thread from the beginning, you will find ALL necessary information on how to flash an unlocked bios so you can alter your wifi card.

Just received my Y410P and going through the posts. Looking through my (stock 3.05) BIOS, there is a option "Allow Rollback". I assume this needs to be enabled before attempting any mods, or does it not matter?

Hi if You can do something with a fan speed please let me know! I tried NVidia inspector and its helps to keep temperature above 83C but in games I noticed that there is a little fps drops sometimes... It's kind of shit that Lenovo is making a productivity witch you can't use! I had several gaming laptops before and the temps where nice and no heating of a palmrest but in y510p the side where ultrabay is so hot that I can hold my hand there longer then minute)))

This looks great! thanks for taking the time to make this. I've been trying to replace my wifi card and this looks like it will solve my issue.

I haven't tired it my self on my lenovo y510p. But i guess it´s you just flash your "original" bios that you backed up before installing the 2.07 Bios. Shouldn't be any problem i guess.

For those who don't like the restrictions put on their system by Lenovo, here's a BIOS mod that will get you back at least some of the freedom you should have over your own hardware.

Features:

- VBIOS tweaked for more performance and better tuning possibilities

Could you please let us know exactly what was changed in the VBIOS?

sorry if this is asked and answered but it won't let me do a search for the word, but does this bios mod let you change fan speeds?

and one more question - would you all say that the intel 7260 linked here Amazon.com: Intel Network 7260.HMWG WiFi Wireless-AC 7260 H/T Dual Band 2x2 AC+Bluetooth HMC: Computers & Accessories is still the best wireless card for this laptop? i'm unable to find if there is an update or one will be coming out soon. i don't have super high wireless needs, but i'm going to try to setup a synology home network soon and it might be nice to be able to transfer to it quickly

That's the wireless card that im currently researching. Seems that others have linked the same card from newegg. Just purchased a new router and would like to take advantage of the ac capabilities.

Hey, not sure if this is the right thread for this but i was wondering if anyone here knows whether the igpu in the lenovo y510p is disabled at a hardware level, in the bios, or some other way when running two gt750m's in SLI. The reason i wonder is because i was hoping to install a windows vm in linux and do a pci passthrough on both 750m's to the vm while running linux on the igpu. Can anyone tell me if this is at all possible?

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!

      In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
