What's the brand and model of my laptop BIOS chip? (without having to open the case).

Recommended Posts

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.

      Hi,
       
      I need help in fixing my Thinkpad.

      I just got a T440p yesterday. It was working perfectly until the following:

      I reinstalled Windows and then I installed Vantage.

      I installed all the latest drivers.
      I also choose to install the bios update. The bios update ran in Windows and it asked me to restart. After restarting, the screen was blank. I tried powering it off and on and I saw the Thinkpad logo but after that the screen was blank.

      I tried powering on and off again and there's no Thinkpad logo now and the screen is just blank with the green power on. No sound, no nothing.


      Here's what I tried:
      Pressing the power button 10 times and then holding it for 30 seconds. Unplugged and battery is detachted Detached the CMOS battery and the reattached it Removed the ram, harddisk and optical disk drive. Attached the battery and inserted the charger. I turned it on and there was a couple of beeps Tried pressing FN+R and created a bootable USB I'd like to ask: How do I fix this? What do I need to do?
      Can I reflash the bios in some other way? Do I need to buy a new motherboard? Will this solve the issue? It's my first thinkpad and I'm really excited but I was bummed out that this happened. Can you please help me?

      Thanks in advance!

      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 !!!

      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!
