Hello,
I have an issue with this laptop. The original BIOS was already overwritten and was not saved before, so I don't have a dump or know which BIOS has to be flashed on this Device. In the HP image for this model, there are four different Versions:
[ATTACH=JSON]{"data-align":"none","data-size":"full","title":"grafik.png","data-attachmentid":3622469}[/ATTACH]​
With two of those (08600, don't know without testing which is the second) the Laptop turns on, but no Display (also not on HDMI) and also no capslock...

So should your BIOS work with mine, or not? My atteched BIOS is my (faulty) dump.

Should this BIOS work also on other Serial Number? [USER="391642"]hoaca388[/USER] Or not?
I flashed it, now i get 3 short + 1 long beep. With original BIOS it didn't beep at all.

Model Number AK9
S/N P8VXVCP (or PBVXVCP, can't tell if it's B or 8)hoaca388Should this BIOS work also on...
