Bios Medion Erazor NH55EPY-M / Clevo NH55EPY

[Danny323]

Hello,

I'm trying to repair a laptop for my neighbors
They said to me sometimes it takes very long to bootup (showing POST).
This was from the first day they got it about 3~4 years ago.
Last years it was getting worse and the problem occurs frequently.

But when is booted it was running fine and fast.
Until yesterday it will not boot anymore.

• 1 fan spins and the cpu/gpu getting warm after some time the second fan will kick in.
• with the key FN+1 (fan test) both fans spin full power.
• No boot
• no display (also not on external hdmi)
• no beeps without memory
• power led is on (front)
• power button led on after pressing it.
• when disconnecting all devices except memory and power button also no response.
• I completely disassembled it and cannot find any visible damage to the board.
• From the service manual I found SYS_PWROK = OK and APU_PWROK = OK

So my last hope is a corrupted bios.

I have a TL866II plus with SPI driver for ISCP but is does not support W74M12JWSIQ.
Like another user here I managed to read something but as "W25Q128FW(1.8V)@SOIC8"

I would really appreciate a working bios dump for this device to compare and flash.

Thank you, This one is working and the notebook is back to live.
i edited the file and added the DMI block from the backup.

now it wont boot because of the w11 bitlocker encryted station.
is there a way to recover the key from the dump?

Thank you everyone,

Saved another one from the scrap pile.

Laptop is working again. I used the bitlocker recovery key from the outlook account backup.
