Thanks mcplsl123 (and jackso_jacker). That link is where I got the BIOS from initially and I couldn't get it to verify, however I do have some good news

Last night, whilst checking this thread for updates, I decided to have another go at flashing the BIOS. This time it went through [I]and[/I] I got a verification I plugged the laptop in and the power button lit up an the fan started spinning and after a bit of fiddling with the internals (swapped ram between slots etc.), I got it to boot! I then spent the next 5 or 6 hours...

OK, I have just stripped the motherboard out and taken a photo of each side. Hopefully the OneDrive [URL="https://1drv.ms/u/s!Amw2pVQ8dZBj0ANPQeHi3cxZj0Nz?e=8szOLG"]link[/URL] will work as I think the files are too large to post directly.

Thanks....

At work I have been volunteered to look after the laptops we use as diagnostic platforms for various motor vehicles, one of which is an HP Probook 455 G1.
Whilst updating the software, the HP update centre thingy said there was also a BIOS update required. I set this going but when I next looked, the screen was black and the white power light next to the power in jack was flashing (steady flash every half a second or so). I left it for a bit to see if it was just still updating but it never recovered.

Re: New Members - please post your introductions here

Hi, I finally decided to join Badcaps after trawling the net looking for a solution to a problem I have with an HP laptop, the forum seemed like a reliable, trustworthy source of knowledge and resources . I have a small understanding of computers and gadgets but I like to learn, and that knowledge is slowly growing thanks to sites like this. With the small amount of free time I have (work, wife, children etc.) I like to 'tinker' with broken things to see if I can get them working again (probably why I became a car mechanic)....
