Unable to Recover Bios HP 15-bs113dx Laptop

[Bumper412]

Hello, I am struggling to boot my laptop: HP 15-bs113dx, following a bios update.

The laptop shows a black screen when trying to boot. I suspected this was a bios issue so I tried to restore the bios trying every keybind I could find (wind.+b/v, esc, F10, F2, shift) but this did not open the bios. I then made a recovery USB using the model and SN of my laptop. Again I tried every keybind and hold of the power button to no avail.

Next, I tried with and without the battery attached. When the battery is attached the power light cycles between red and white. Without the battery, the light is just white.

I noticed these users have a similar issue: https://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/BIOS-Update-for-HP-15-bs-1xx-Failed-and-Brick...

Any advice?

Hi @Bumper412,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like your HP 15 laptop is experiencing a BIOS failure, which can be tricky to recover from. Here’s a structured approach to troubleshoot and recover the BIOS.

Perform a Power Reset

• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for 15 seconds to drain any residual power.
• Reconnect the power adapter without the battery and try turning the laptop on.

Use the BIOS Recovery Feature

HP laptops often have a built-in BIOS recovery system:

• Create a BIOS Recovery USB:
  1. Download the BIOS recovery software for your laptop from the HP support site.
  2. Use a working computer to create the recovery USB drive as you already did.
• Initiate Recovery:
  1. Insert the USB drive into the laptop.
  2. Hold the Windows key + B (or V) simultaneously, then press and hold the power button for 3-5 seconds before releasing.
  3. If successful, the screen should light up, and the BIOS recovery process should begin.

If this doesn’t work, retry the process while holding Esc, F10, or F2 instead of Windows+B.

Inspect the LED Indicators

The LED light patterns provide clues:

• White light: Indicates power is reaching the system but doesn’t confirm BIOS functionality.
• Red/White blinking: Can indicate a hardware failure or a corrupt BIOS.

Refer to the HP website or your manual for the specific blink codes. Typically, 2-3 blinks might signal a BIOS issue.

Clear CMOS (if applicable)

If your laptop has a removable CMOS battery (a small coin-cell battery on the motherboard):

• Disconnect the main battery and AC adapter.
• Locate and remove the CMOS battery for about 5 minutes.
• Reinsert the CMOS battery, reconnect power, and try booting.

Attempt USB BIOS Recovery Without Display

Sometimes, the screen might stay off, but the BIOS recovery could still proceed:

• Insert the recovery USB.
• Power on the laptop and wait for about 10 minutes. Look for activity on the USB (flashing light) or changes in the power LED.
• If the recovery completes, the laptop should reboot automatically.

Note:

• Use only the specific BIOS file for your laptop model and Serial Number.
• If you suspect a hardware issue, inspect the RAM and storage drive connections by reseating them

I hope this helps.

Take care and have a good day.
