lenovo Flex 5 bios need

[peste]

Hello, i need bios rebuild or dmi and widnows key trasfered. Turns on, black screen, no post. Tried dump with no dmi (from #3 post) computer turns on, works perfectly.

BOARD LC55-14A 19793-3

now you have everything you need at post #3...transfer DMI AND KEYWIN yourself...
the bios from post # is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

I ordered new BIOS chips. I'll try and report back once I receive it.

Thanks.

Thanks, qayyum786. I made a rookie mistake in my haste to flash the BIOS. I forgot the battery was still when I was placing heat tapes on resistors and capacitors around the BIOS chip to prepare for desoldering the BIOS chip. I ended up shorting the BIOS chip (it burned). I replaced it with the same part number from a donor board and flashed your bin file but now there's no power. The laptop doesn't turn on anymore. I tried with battery only, power adapter only, and battery with power adapter with the same results, no power. I guess I might have damaged other components besides the BIOS chip

This is the end of this repair for me.

Thanks, everyone for all the help.

Cheers!

Thanks, Hoaca388 and Shiyab for the files.

I tried Hoaca388's file and it worked. I have display.
However, I lost DMI info (S/N, Model #, UUID and Windows Key) as shown in the picture.
I tried using the Lenovo Uone tool to write the DMI info but I get an error "Locate protocol with LenovoEeprom, status [e]"
"Eeprom fail when reading or writing data."

Is there a way to fix the DMI tool error? I'd like to try that first if possible since I'd prefer not to desolder the BIOS chip again.

shiyab does your file retain the DMI information so I should go ahead and try that if I'm unable to write the DMI info with the tool?

Thanks, again for the help.

Cheers!

Hi everyone, it`s me again this time with a question: is there a method to upgrade/flash the BIOS of the Lenovo Ideapad Flex 5-14ITL05 Laptop - Type 82HS using a bootable pendrive?
I`ve search the Internet but I haven´t found a way to do it in Lenovo laptops. Thanks.

hello you found a solution I have the same problem as you on the same computer and the same motherboard thank you.

[SMDFlea]

Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules. Not as a picture, part of the file name and so on.
