    Can't use flashrom

    Hello,
    I'm new to the site and have a general question about a laptop I have.

    It is a HP Zbook 15u G2. I have attempted to get a backup of the bios with a bios clip attached to a CH341A. The board has 2 chips on it. One is a W25Q16.V which I can read and backup (only 2.1Mb in size). The is not readable because it is not supported by flashrom. It is a MX25L12873F and seeing as the other chip is only 2MBs I believe the bios is held on this chip.

    Is there anything I can do to remove the password lock on this laptop?

    Thanks

              Common SPI bios chip programming Questions and Answers
              ----------------------------------------------------------

              Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

              A: If you can`t read from it how do you expect to write to it ?.

              Q: Why is my bios chip unreadable ?.

              A: The programmer is faulty or has a worn or broken zif socket.

              The USB cable is frayed,connector pins worn or some other physical damage.

              Not enough amperage or voltage to power the programmer properly.

              APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
              by sam_sam_sam
              This started a few days ago and does this about every 8 hours

              After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

              The battery backup is about 3 or 4 years old

              Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

              by Chris_stand
              Hello,

              i hope to find help her in the forum. It is a littlebit tricky. I searched many Days about disabling IntelME that was may major task. So i have a Clevo PD50PNN motherboard.

              Backup worked but since the backup the Laptop is not booting anymore. I flashed the newest Version oft the BIOS with success, verfiy everything ok.
              But the...

              BIOS Backup / extract 16MB .bin - Lenovo ThinkBook 13s G3 ACN - 20YA0005GE
              by DiddiAb
              Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.

              I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost...
