                  Chip MX25L12873F

                  Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.

                  2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.

                  The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...

                  Lenovo LOQ mdl 151RH8 bios Q: Can't get usb boot to list
                  by Max029
                  I've searched and read Beginners guidelines and other sticky threads. This is just a simple bios question. If I may, I'm having trouble finding any help, including from lenovo tech support & forum, for how to get usb boot to list in boot options. I'm trying to run memtest86 so nothing as highfaluting as re-install, flash a bios, etc.

                  I've made usb boot enabled and secure boot is disabled. I can find no other option in bios ver LZCN34WW (the original bios). Would anyone here be familiar with LOQ or Legion bios versions & know what is going on?


                  TY,

                  Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                  by Wahaz
                  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....

                  Lenovo P1 g1 Type 20MD-002PUS "BIOS Help Needed"
                  by cyber16
                  Please I need help.

                  Quick rundown long story shorter, but still long winded.
                  I received this Lenovo P1 GEN 1 about a year ago from a business.

                  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.

                  Then late last fall my father-in-law suffered...

                  Lenovo ThinkPad L15 Gen 1 i7 (20U4) Bios and EC dump needed
                  by Joluvillas
                  Hi all! I was reading on tutorials how to flash a bios to remove password from a bios, and I ended up reading the EC chip instead of the main bios chip, it only gave me a .bin file of 1,024kb, I learned later that that is the EC chip not the main bios chip (I should have read the tutorials here instead before attempting anything, my bad), I went to flash the original backup, the 1,024kb size file into the same chip and laptop is not powering up anymore. I may have screwed the chip or even the motherboard (Hopefully not), I am trying to see if there is a fix before I discard it. I had a couple...
