Re: lenovo g505
well, board code doesn't really matter in this case, unless you do bios mods, what matters is the product name (lenovo G505) and model name (e.g. 1066).
Anyway, here it is (if ala_borbe and meritosari BIOS doesn't work for you).sigpicComment

Re: lenovo g505
Hi
I realise this thread is a little old, but I've recently been helping someone with a Lenovo G505 which had a 'no display issue' on the laptop screen but was fine on an external monitor.
However I discovered a way to get correct boot so that laptop screen display is visible (including Lenovo splash screen, and incidentally, the webcam to be recognised correctly in device manager) was to press power on button and immediately close the laptop lid and reopen it, i.e. open the laptop screen just enough to press the power button, then close and open virtually straightaway.
Does anyone know if any of the bios files available from this thread fix this problem or are they for some other 'no display issue'?
ThanksComment

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the commandit should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.Code:
"innoextract 7wcn38ww.exe"
The trouble I'm having is that I'm not getting the newly... -
For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

I'm working on a Lenovo LOQ 15APH8, Serial# MP2L9MAV. I want to flash a new BIOS onto it, but I'm also trying to learn this process for my own enrichment and professional development.
I was watching some tutorials, copying the serial info blocks from the old bios to a new bios. Before that though, they use innoextract on the Lenovo .exe. I downloaded Innoextract v1.9 but it tells me my .exe is not a supported inno setup installer(see screenshot). So if I unpack this using 7zip, I do get a .ROM file, but according to my tutorials, I'm looking for a .FD file.
How can...
