Hello everyone,

I have two HP 840 G5 laptops. One of them is missing the BIOS chip. The second one was fully functional — it powered on and worked properly.

I desoldered the BIOS chip from the working laptop, dumped its contents (I'm attaching the original BIOS dump from the second laptop), and flashed a new chip for the first laptop using that same dump. After this, neither of the laptops powers on anymore.

Now, both laptops have the same issue:

• When turned on, the Caps Lock LED blinks 5 times,
• The CPU fan spins at maximum speed,
• After a forced shutdown (holding the power button for 10 seconds), the laptop turns off but then automatically turns back on after a few seconds,
• This cycle repeats endlessly.

What could be the cause? I flashed the same BIOS dump I extracted from the working laptop, made no changes — but after soldering it back, it no longer boots.

Could you please send the correct BIOS dumps for both of these models?

• Laptop 1: M/B SPS: L15518-601, CT: PGWHT00WBBZ8QZ, SN 5CG9093W7B, Prod ID 2FA66AV
• Laptop 2: M/B SPS: L15518-601, CT: PGWHT00WBCDLHI, SN 5CG81516RB, Prod ID 2FA66AV
