90b issue on startup on HP Spectre laptop - fan revs to maximum then cuts out

[Raihaan_]

Not sure if anyone has experienced anything similar, but on powering up the fans go to full power (or close) and shuts off completely within a second. Then the 90b error is displayed. I have continued to use my laptop since it happened yesterday and everything seems normal once I let it resume booting.

Since then I've installed the BIOS update to F.41 but still no luck. I've tried a hard reset but I'm not sure I'm doing it right (it keeps rebooting after 15 seconds... is that right?)

I've booked it in for repair, but if there's a fix I can do at home that'd be helpful. Any advice would be great!
