HP Pavilion 15-eh0xxx DAG7HAMB8E0 Bios request

[HaiPa]

Hello guys,

Can anyone help me with a bios fix, my laptop is powering on and sometimes I do get a message on the screen that the bios is corrupted and needs updating. I have tried updating the bios downloading the newest version from Hp website and create a stick using the tool with no success.

Laptop in question is:
HP Pavilion 15-eh0511sa
S/N 5CD0522KNV
board : DAG7HAMB8E0 Rev.E
Ryzen 5 4500u

Many thanks

Edit: I did try to write the bios extracted from the HP : 087C5 and 087C6 but with this 2 I did not get at least to post to the error message, only tool I have to write and read bios is CH341a usb reader, not at the pro level to remove the chip from the board.

You didn't transfer the DMI or the Windows key, besides it will boot in MPM mode!
Once you've started helping, do it right

[HaiPa]

still no luck, now only getting the fan to spin, the cpu gets hot and no back light on the screen to flash, at least with the last one was getting the message to pop on the screen. will trial more things tomorrow after work but thanks for your help man.

[Vesko356]

You must erase the SPI chip before flashing, always use verification. After programming the chip, read it again and compare the content to be sure you've programmed the chip properly. For best results with CH341a use NeoProgrammer V2.2.0.10 software.

Hi Vesko356 ,

Thanks for the Hp bios

"Laptop in question is:
HP Pavilion 15-eh0511sa
S/N 5CD0522KNV
board : DAG7HAMB8E0 Rev.E
Ryzen 5 4500u"

Hi have follower your steps, and at the first attempt to turn on, I get the system bios image is being cleared

I have checked as you suggested both what i have write and the image you posted and they are the same, however after I turn the laptop on, I get that message then restart, and black screen with fan on.

You thing there is different issue with the board?

as even when I have tried other images, its asking me to write a usb with recovery image, but no luck with that one either as is not seeing the usb. end restarts all over again.

Thanks again
