Re: Lenovo ThinkPad Edge E531 BIOS
How do you program these Dump files into the Bios? Does the bios chip need to be removed? Or can these files be flashed within windows with flasher software?
Thanks.Comment

Re: Lenovo ThinkPad Edge E531 BIOS
Why would you want to flash a dump if your laptop boots to Windows.
But answering your question - no, usually it doesn't have to be removed but you still need an SPI programmer attached to the bios chip. Newer laptops can't be programmed with dump files within an operating system.Last edited by RethoricalCheese; 12-31-2019, 01:00 AM.Comment

Re: Lenovo ThinkPad Edge E531 BIOS
Because I have a E531 that someone put a stupid supervisor password on the bios. So now can only make minor changes to the bios settings. I found a flash that would clear out the supervisor password. But sounds like I will need to have a programmer attached which I don't have.

I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele... -
Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.
I have a few questions:- If I would buy this laptop and have

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 -
Hi i have a Lenovo Edge E531 with a CPU 2.2GHz (Intel core i7-3632QM) with firmware HEET35WW (1.16) upgraded with Win 10 OS.
Have a issue that my boot menu vanished in bios.
When trying to boot system, screen is just black.
If trying to press F12 at startup the screen is black and all one can see is a blue marker blinking up in the left corner of the screen.
I have tried loading setup default in BIOS, this did not help.
I have tried removing, battery and bios battery and connected both batterys back and then booting system again. but this did not resolve... -
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....
