HP DV8-1200 Series 90b Error Mod Removal

[robzmtech]

Hi guys,

Ive pulled this laptop apart 3 times now,

brand new fan, brand new heatsink replaced, top quality thermal compound.

Im baffled the error still comes up the usual 90b fan error press enter to continue.

Laptop runs cool very cool, fan does spin throughout RPM range (high/low) 

Its not a cooling problem as the laptop is not overheating at all.

Anyone that can help me! I do not want to buy a new motherboard which is expensive when their is nothing wrong with the cooling system I use the laptop 247 no issues no heat.

I need a mod or someone to help me get rid of the HP error on bios boot press enter to continue 90b fan error.

Ive tried updating / downgrading bios from current version down to last 3 older versions to no avail.

Ive also tried the modded F.25 bios on this site which unlocks advanced bios features still did not fix the issue.

thanks in advance.

Robbie.
