Re: Lenovo flex-15iml MODEL NAME:81XH NEED BIOS DUMP
Try and make another backup,its more reliable to desolder the chip if you have the tools.If you havn`t and you are using a clip make sure it doesn`t wobble about and it makes good contact. Make 2 backups and compare them with a hex editors "File Compare" function, and lookat the files to make sure there`s some code there other than all FF`s.Comment

Re: Lenovo flex-15iml MODEL NAME:81XH NEED BIOS DUMP
Yo got me yes I am using a ch341a with a clip. I am able to get it to read but the chip is not listed with the application I'll try pulling it again.Comment

Re: Lenovo flex-15iml MODEL NAME:81XH NEED BIOS DUMP
FYI I had to rar the bin file which is 64 kb. since the site would not let me upload a .bin file directly. I can see that there is hex data. My fear is that the ch program is not detecting the proper chip and is pulling less data than it should.Comment

Hello all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
Hi, I hope this is the right place to post this. This is my first post on this forum.
A friend helped me get a prototype Lenovo motherboard from China, it's got a hole drilled in it but I'm working on trying to revive it to some degree. I dumped the bios in hopes that it might be useful to someone, since this board is configured with the 3rd NVMe SSD slot and maybe it is useful as a reference for modding another bios to support this function. For example the M90q Gen 2 / P350's unpopulated 3rd NVMe slot footprint maybe.
This bios dump is straight from the chip, nothing has been... -
Lenovo X1 Carbon 7th Gen Type 20R1
SN: PF1Y5BBJ
Board: GX490 NM-C661 Rev: 1.0
I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.
The problem with the laptop is that... -
So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -
Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM
