HP Laptop System Fan 90b Error 

You are a pro. Only video I found that got to the root of the problem. Too bad the flux/solder and availability of MB spares may be out of reach for DIYers.

Brilliant, i would never have thought to look for a missing component. a really good fix.

Wow! Those fans are loud!! Thank you for the fix!

I have the same issue & don’t want to spend hundreds for a simple fix. It’s the same laptop.

a really good fix. thank you

I have same board, same problem, but i have the resistor over there and is good, replaced both fans still no joy. What else could be? Or what area to check? There's no schematic available for it...😢

Can you share part number you replaced ?

is it the ssme for a hp model 14?

I got this error. Restarted and it gave me a BIOS update and it seems fixed.

Very nice good to have dooner board

i fixed the fan by disassembling and put some lubricant. now error is gone. the fan at first is pretty tight ( the fan wont turn when i blow with my mouth). when i put some lubricant the fan is now smooth

im having this problem right now with my HP Omen (15-en0023dx) and i think the left fan just stop working for some reason and i maybe needs to replace it.....

The same error happens to me only 1 or 2 times a day, I called the warranty and I did the uefi tests and they all come out fine and they tell me that if it comes out again to speak and I have already spoken 3 times and they always tell me the same thing

i have same problem both fans not spinning while both fans are fine and no rpm showing and i got that message Fan 90b Error do you have any idea why?

Sometimes I get this error sometimes it goes away. Does it have anything with the BIOS? If so how can find out? (Fans are perfectly fine)

ｐｒｏｍｏｓｍ 😥
