    Need BIOS for HP Pavilion 15-n058sr recovery - Caps Lock blinking twice

    Hello everyone,

    I'm dealing with a classic BIOS corruption issue on an HP Pavilion 15-n058sr and hoping someone here might have the original BIOS file or point me in the right direction.

    Symptoms:
    • Laptop powers on but no display at all (completely black screen)
    • Caps Lock blinks twice with a pause, then repeats continuously
    • F12 LED stays on permanently
    • No POST, no boot sequence, nothing on screen

    Based on HP diagnostic codes, the 2-blink Caps Lock pattern indicates BIOS corruption/failure.

    What I've tried:
    • Hardware reset (battery removal, power drain for 30 seconds)
    • Crisis recovery attempts: Win+B+Power and Fn+Esc combinations during boot
    • Searched extensively online but couldn't find the specific BIOS file

    Laptop details:
    • Model: HP Pavilion 15-n058sr
    • Product ID: E7G13EA#ACB
    • Originally came with Windows 8

    I understand the risks of flashing incorrect BIOS versions and want to make sure I get the exact match for this model. If anyone has this specific BIOS file or knows a reliable source, I'd greatly appreciate the help.

    Also open to any other recovery suggestions if I've missed something obvious.

    Thanks in advance for any assistance!

      Dear SMDFlea,
      I'm repairing this laptop for another person and want to be respectful of their privacy. Could you please help me with just the Product ID (E7G13EA#ACB) and model (HP Pavilion 15-n058sr)?
      If the serial number is absolutely required for BIOS identification, I will ask the owner's permission first.

        HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
        by Bloodhoundje
        Hi everyone,

        I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

        I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

        After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

        I have desoldered the bios chip (GigaDevice...

        🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
        by macabook
        Hello everyone,

        I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
        🧩 Initial Issue
        • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
        • External display (HDMI) shows
        ...

        ASUS Zenbook Pro Duo UX8402ZA BIOS
        by pirati
        Hello everyone,

        I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

        When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

        I decided to try flashing a new BIOS, but since I didn’t want to desolder...

        Dell T7820 stuck in Bios Recovery Mode
        by The_Memory_Guy
        HI,

        I have a Dell T7820 stuck in Bios recovery mode. I never get Dell Boot screen or anything visible on screen. The system just gives me 3 white lights and 3 orange lights indicating Bios recovery mode.

        What I have tried to get to recover the Bios, there seems to be some conflicting advice about recovering the system.

        All of them say to download the latest bios from the dell website which is a .exe file. I have done that

        Dear Forum Readers!

        I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
        I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
        The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
