    HP 9480m BIOS Read Problem

    I have been using a ch341a programmer with a SOP-8 clip to read and program the BIOS chips on HP Elitebook 9470m laptops. It works.

    But I have two BIOS locked 9480m's that I haven't been able to read up to this point and I'm running out of options.

    The chip has "25Q128A 13EC0" on it which I interpret as a Micron 1.8v SPI. I hope that's correct.

    I ordered a 1.8v adapter for my CH341A and no matter what I get "no chip detected"... I've tried every orientation. I'm actually thinking the 1.8v adapter might be bad.

    Is there anything else I can try? Any suggestions?

    Usually when i get "no chip detected" error then driver should be reinstalled on ch341a.
    Also are you using NeoProgrammer?

      Problem with PANASONIC CF53 laptop after changing BIOS settings
      by AquaMan Ua
      Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

      M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.
      by hotcrossedbuns999
      My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
      1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
      2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
      3. I could only locate two chips that look like bios chips. Could someone verify this

      TONGFANG "GM7TG7P" Bios Password Problem?
      by traxformania
      Hello,

      I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

      But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

      I'm trying to reset my bios without success.

      I tried :

      -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

      Problem Flashing Macronix MX25L6445E BIOS Chip with CH341A and EZP2019+ on ASUS X455LD
      by pengamat_hebat
      Hello everyone,

      I'm trying to flash the BIOS chip Macronix MX25L6445E from my ASUS X455LD laptop using both a CH341A and an EZP2019+ programmer, but I keep encountering issues.

      Reading the chip works perfectly, and I can extract the BIOS dump without any problems.

      However, erasing and writing fail every time, regardless of the software I use. (Neo, asprog, ch341, etc)

      I also tried applying 3.3V to pin 3, but it still didn't work.

      I attempted to unprotect the chip, but when I read it back, the registers remained unchanged.
