How to copy DMI serial number and other details from stock dump to new bios with hex editor? Windows doesnt allow to login. Says not possible since security settings are changed.
And bios from lenovo website is larger.

Hi, I'm troubleshooting an IdeaPad - voltage rails seemed to be fine (I could not find schematics, they are only after a paywall) so my next guess is the BIOS.
Mine is in a Winbond chip - W74M12JWSIQ. My MiniPro cannot read it and even if I tried some substitution (my guess was W25Q128BV) but still no luck. (I desoldered it of course)

If anyone has a workaround for this I would be glad.

Thank you

if the programer has a support of that chip that should work but if not you should look for a programmer that support that chip

I have managed to get it running via minipro, but as a "W25Q128FW(1.8V)@SOIC8" IC.

What should I do now? What info should I post here so that you guys could help me, or what do I have to do myself?

Read the thread before making a new request.
Or at least posts 36 and 90 for example.
Everything you need to prepare yourself a new bios is already posted here.

[jovani1989]

I was with the laptop to a repair shop, and they checked the motherboard and they said that everything seems to be fine no shorts, no problems, they tried to flash another bios but same problem! Is anything that i could try or shoud i trow the laptop to bin!?

Hi, sorry for my bad English, but I have a Lenovo IdealPad Flex514ALC05 with a black dial, I think I have the voltages, the white power LED flashes only once, the keyboard turns on, the fan can be heard turning. I tried to download the bios with the default Xgpro T56 programmer, but I don't think anything is corrupt. Now I kindly ask if anyone can help me find the bios for this machine.

You MUST:

• Post under a related thread if it exists

Upload your bios backup even if it's corrupt.

Good evening guys, having a corrupt bios file I had to download several new bios files, but when I go to load them on the XGECU T56 programmer all the folders are empty where is the error because what am I doing wrong. Please can you help me understand, I thank you very much..

[Vesko356]

You're off topic here. If you have difficulties using the programmer make a request in a Equipment Usage, Soldering, Techniques, and Reviews section.
I'll suggest to read the user manual first.
