HP 15-bs109np keeps corrupting bios

[Vspeed]

Hi,

Have this laptop that wouldn't show any signs of life, sometimes had a bit of fan spin, others, just a very dim CAPS LED blink.
Cleaned dumped ME bios region, the laptop power on fine again. After turning it off, it shows the same behavior.

What is causing this?

Uploaded original dumped bin, original ME cleaned bin and untouched bin files from HP website.

Thank you.

Have an update. Just flashed the cleared ME bin again, and the laptop doesn't boot. Just the power LED lights up. No HDD activity.

Can I just flash any of those bin files? shouldn't some serial numbers be copied over from the original bin over to those?

Check the chipset support with ME Analyzer. There`s no need to post them. HP bundle multiple updates for different machines in the same update.

084D4 is Gemini Lake

0832D is Braswell/Cherry Trail

0832E is Apollo Lake

08445 is WPT-LP Wildcat Point

The 15-bs109np has a i5-8250U CPU , Skylake/Kaby Lake . 08328

Flash the bios at post #2 ,its a virgin bios with clean configured ME FW . If it doesn`t work then its a hardware problem.

Yeah, flashed #2, the laptop powers on, there is fan spin, then it powers itself off after around 10s, not powering on itself again.
When pressing power afterwards, there is a shorter fan spin and the CAPS LED seems to flash randomly.
Which hardware issue can it be? It powered fine once after cleaning ME, now it's not doing it again.

Problem solved.
Upon close inspection to the side of the board facing the keyboard, found a slight corrosion or water damage in Q21 located close to the usb ports.
