Lenovo ThinkPad T490s Bios Flash
Hi all,
I recreantly acquired a Lenovo T490s from a house clearance and I have no way of getting the bios password. The laptop seems to work fine apart from the password lock. I've bought myself an EZP 2019+ high speed programmer to try to flash the bios.
Just before I attempt this could anyone please confirm that the item circled is the correct bios and is it ok to flash the bios while the chip is still attached to the board.

by zeniusHello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...-

by RMDUiFTGood 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

by WahazHello,
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....-

by baaligogaGood day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...-

by HammyCheesyHello all,
I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."
When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).
Type: 30BB
Model Number: S03600
S/N: MJ07N68C
Things I have tried:
1. Reseated all components, pulled everything except for 2 RAM modules (1 per CPU)
2. Attempted to boot with just a single CPU...-
