    Lenovo T520 BIOS needed.

    Hello. I need a stock Lenovo T520 BIOS image as my modified BIOS will not produce a working coreboot image.

    The T520 and T520i share the BIOS image.

    I need the 8mb MAIN.

    Thanks!

    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

                  are you able to share the precompiled coreboot file?

                      ^ The T520 and T520i share a BIOS, however due to differing hardware addresses coreboot can't be compiled for both. I built coreboot for the T520i, if you have that, my coreboot build will work. Otherwise, it won't. If you still want it, i can upload it.

                                                                                  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....

                                                                                  I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                                                                                  This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                                                                                  I have opened the laptop and identified the main BIOS chip...

                                                                                  I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

                                                                                  Here the steps I have taken to fix the laptop:

                                                                                  It was pretty much dead hit the power button and the LED on the power light would come on as would the keyboard back light a couple times and just shut off or go into high speed fan mode without life other than the power button led.

                                                                                  At that time it was still under warranty, I spoke to Lenovo and I was going to send it in to have them repair it.
