    Bios work ok. Now problem with USB3 AND ram slot not work. Is hardwae problem, I think the PCB was flooded on the side with the usb3 sockets etc. The keyboard clicks strangely from that side.
    Thank you volinakis.

    I need a working bios after repairing the motherboard, I replaced the shorted capacitor CS8 on the +5VALW_CC_VOUT line, everything seems to be fine now, but after starting the current stabilizes at ~0.25 A and there is no voltage on the processor. A bit strange. Please provide a good bios, I am adding a screenshot from my board.

    "Resolve system can not resume when battery under 6%" this is what it says on the manufacturer's website with the oldest BIOS version. The laptop only works on the power supply.On the +- pins of the battery when charging 0.8V. Meybe i need good batery to boot new bios.

    the laptop stays on, I tried another screen but it's the same, when starting the screen goes to a black background, I thought it was the backlight but I don't see absolutely anything with light, I I have tried many screens, it does not display externally either, perhaps it will be necessary to reprogram the SIO?​


    I saw that on post 6 there was the EC bios too, but on the motherboard I did not find another eeprom chip even smaller, so the program must be done directly on the SIO? Unfortunately I don't know how to do direct reprogramming on the SIO, if you have a tutorial to do it I'm interested, thank you

    Can you clean my original bios please

    Acer Nitro 50-640E Corrupted BIOS Dump
    by James194zt
    Hi,

    My daughter has accidentally managed to kill her Acer gaming desktop it has a blank screen after updating and when you press the power button the fans spin, light comes on and it makes 1 long and 1 short beep and no attempt to boot.

    All basic troubleshooting has been done we replaced CPU, GPU and RAM from a working machine and no joy, I also noticed a post on here with the same issue and it was the BIOS. I am pretty sure also because it was doing a BIOS update that stopped it working, she knocked the keyboard out by accident during the update and the screen just went...

    Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
    by Ahari
    Hi all,

    This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

    I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

    I...

    I need a BIOS dump for the Samsung S49CG934SU monitor
    by Habble7
    The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

    Suspected Cause:
    I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

    Troubleshooting Attempts:
