Re: Hp 15 la-c921p

so, i've solved the problem.
you should use standard hp's application for BIOS upgrade, and choose there an option - save BIOS (for advanced users). then, need a blank flash drive with fat32. copy all files with names *.bin and *.s12 to the flash drive, root. then put flashdrive in usb of broken HP laptop.
put away adapter and battery. press on the keyboard windows+B, hold, plug in the charger, and then, keep pressing all these buttons, press Power. after it turns on - release buttons.
bios will upgrade.

Hi there! I have same problem. maybe it is videochip? but its comes with cpu together...
or if its a bios, we should find a working sample with new version and grab it from the chip, right? have you found one?
