Re: lenovo Flex 5 bios need
Hi,
(edited after rightful comment from Vesko365)
i have a bricked laptop. I know it is the bios. I flashed a version that was posted in the beginning of this thread and the machine started up again.
I have made a backup beforehand and added this as an attachment.
If possible could someone provide me a bios with the my DMI information copied to a new BIOS.
If needed i can provide the cap file.
I would also be happy with the correct offsets so i can try it myself.
machine information :
idea pad flex 5 14are05
model name 81x2
serial r90xzmv3Last edited by odieben; 04-29-2023, 06:04 AM.Comment

Re: lenovo Flex 5 bios need
Hi Everyone,
I have the Flex 5 -14ARE05, Esc and Caps Lock lights are on, black screen, fans kick in when required and the laptop charges.. From what I have read on here these seem to be the same symptoms that others on here are getting therefore re flashing their bios to cure the problem.
I have tried flashing my bios and a number of bios's from this thread only to end up with exactly the same symptoms, nothing changes no matter which bios I flash. I am using the CH431A V1.7 which allows me to select 1.8v without an adapter. This I have also confirmed with a multimeter. My bios chip is a MX25U12873F and my logic board is a LC55-14A.
Can anybody help me with this issue?
Many thanksComment

Re: lenovo Flex 5 bios need
if it doesn't work, either you wrote the bios with errors or the laptop has another problem.. use the HxD program to transfer the DMI information from one bios to another.. enter both bios into the program and then (copy-paste) from one bios to the other.. the interval ( DMI) which must be copied, you can find it at item #51..If you have found our forum useful please consider supporting us.

my laptop is lenovo flex 5 14ITL05
recently my power supply for this laptop developed a fault.
which caused a short in my usb c port -- verified with a new charger.
rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32... -
Summary of BIOS Whitelist Removal Problem
Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
Initial Findings:- My current BIOS version is N1KET58W (1.45).
- I have a CH341A programmer and have successfully created two full backups of my BIOS.
- I have the ability to use command-line tools on a Linux machine.
- I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI

Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
