Hiya, thanks for the response - the onlyother two chips I can see that look BIOS related are two Winbond W25Q80EWSIG 1mb chips - I've removed the one nearest the CPU/GPU and dumped an image - is that the one you mean?...

Hi,

I have a laptop here which is powering on, fan spin etc but nothing on screen or from HDMI out - power light stays on until turned off manually so appears to be somewhat functional so suspecting a BIOS issue.

I've tried flashing the 3 different versions of the BIOS from the HP websiute, but all give varying results (beep codes) and still no POST. Unsure as to whether this might mean a deeper issue, but hoping that someone can take a look at the BIOS dump I took and see if anything is obviously wrong?

Model is 15-DH1005NA Serial CND0430QWL Product ID...
