Lenovo Y50-70 Bios Reset

Recommended Posts

Hello Guys,

 

If anyone is having BIOS config issues like if you changed an option then saved and the laptop won't start, i'll give you some steps to follow to reset the BIOS on a Lenovo Y50-70.

***FYI: I haven't tried this on any other Lenovo laptop so feel free to try it.***

 

WARNING: *****For this steps i recommend a 2nd person to tell you when the laptop power cycles on and off for a few seconds on a couple of the steps below.*****

 

-Step 1: Open up the laptop and unplug the AC Charger, CMOS Battery, Laptop Battery and RAM Modules.

 

-Step 2: With everything UNPLUGGED, press and HOLD the Power button for 30 seconds.

 

-Step 3: Connect the AC Charger to the laptop and turn it on, at this point the laptop should turn on and turn off every 3~5 seconds, leave it like that so you can know the interval of time that you have.

 

-Step 4: While it's OFF, quickly connect the CMOS Battery, wait for it to turn on and off again.

 

-Step 5: While it's OFF again, quickly connect 1 RAM Module, wait for it to turn on and it should give you the "Lenovo" BIOS logo at this point. *You can wait until it reaches Windows to turn it off or just press the power button.

 

-Step 5: IF you're good, you can proceed to leave it OFF and connect the other RAM Module and the Laptop Battery.

 

-Step 6: Close your laptop undertray and power on and make sure to setup your BIOS once again because this will load bios defaults.

1. Completely disable laptop with long press and hold the Power button.

2. Press and hold F2 button, and start laptop (to go in bios setup menu).

3. Press F9 button, then Enter button. Then press F10 button, then Enter button.

I had the same problem here with Lenovo G500 and I must say that Klems method saved my life and it worked ! The difference is that with G500 You have to press FN + F2 and so on with rest Fs. This method restores default BIOS setup.

Thank You Klem !

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?

      Hi!

      I would love to have my BIOS modded to disable the wireless whitelist.
      I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.

      Laptop: Lenovo ThinkPad S440 (TYPE 20BB-S00400)
      BIOS version: 73ET71WW (1.71)
      Original WiFi/BT card: Intel Wireless-N 7260 (7260HMW BN) (vendor: 0x8086, device: 0x08B2, subdevice: 0x4262)
      Target WiFi/BT card: Broadcom BCM94352HMB (I haven't received it yet, waiting for delivery)

      Manufacturer BIOS download: bootable ISO, updater for Windows
      My BIOS dump (using CH341A SPI Programmer under Linux): http://www.mediafire.com/file/mn0gfr9ext7yqrn/S440_73ET71WW.bin/file
       
      Thanks!

      In this thread you can post your requests for Lenovo Y50-70, Lenovo Y70-70, Lenovo Z50-70, Lenovo Z70-70, Lenovo G50-70, Lenovo G70-70.
      If someone want upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread. Also, if you have a problem with fan pulsating/clicking on any modified bios then you can post your request in this thread.
       
      The flashing procedure include two steps:
      1.  Flash main system bios.
      2.  Flash EC firmware.

      Hi folks,
        Greetings from Brazil!  Not sure I'm posting in the right place, but I have a question:  how do I find out the brand and model of my BIOS chip without having to open my laptop?  I can't find this information anywhere.  Been searching for days... I have a Lenovo Ideapad 300-15ISK 80RS (motherboard Paris 5A8).  Thanks a lot for your time and help! I really appreciate it!   Best regards,   JC.
