How to fix Error 90b on startup

Hewlett-packard / Omen 15-5010nr

Specs: Windows 10, 4710hq ddr3 Micron
Please post a solution to have the system ignore the bios error! I fixed the fan myself! I own an HP Omen 15, it puts my processor and gpu into low power. It makes my laptop unusable for gaming.

Is this a laptop?

When you fixed the fan did you clean all of the cooling vents and areas where dust accumulates?

Try powering down the computer and remove all power sources such as battery and power connector.

Once all of the power sources have been removed press and hold the power button for 20 seconds then release.

This will flush any charge that the capacitors are holding.

Reassemble the computer by attaching the power sources and power on.

Does the error message still display?

Did you use a vacuum cleaner on the laptop?

Tried that twice already, the fan didnt have dust, the mobo connectors pin was bent. Still running just as slow. Thanks anyways.

I wasn't suggesting you use a vacuum cleaner on it. That can zap the electronics with static discharge.

Explain the bent pin on the MB.

"I fixed the fan myself!"

What pin could you have bent that would effect performance? Please explain what you did.

The fan header on the mobo has 4 pins, I must've bent the 1st pin on the left. I ran a wire from the inside of the fan connector (on fan) into the space where the bent pin was. The fan turend on when I booted my pc, yet still showed the error message. I really need a solution, I normally do light gaming (CSGO, Fallout 4) and can not use the 860m in it. The fan error lowers my core clock on cpu to 800mhz and gpu to 34mhz. Why would they do that?

A 4 pin header allows you to view fan speeds adjust fan settings in the BIOS. You can set to conserve power and control noise or possibly have the fan run faster or not at all.

If the clock speed is being slowed the CPU is doing that to prevent overheating.

Post the EXACT message you are seeing.

You still haven't explained HOW that pin got bent. Now it appears you actually broke the pin off. Why were you inside your laptop anyway?

90b pretty standard error. The temps are very low idle ~30 gpu and cpu. I overclock my gpu and was changing thermal paste (to Kryonaut) and bent the pin on the mobo. Still of no help. I believe the bios doesn't detect the fan working, and thinks the system is overheating so underclocks both. I need a way around that.

"I ran a wire from the inside of the fan connector (on fan) into the space where the bent pin was." Getting a straight answer from you is difficult to say the least.

Did you or did you not use a vacuum cleaner on the laptop?

Is the pin bent or gone?

Why were you messing around in there?

What else did you do?

Have you tried reading the system temperatures while under load with a third party utility like HWMonitor?

Do you hear any alarms indicating overheating?

Fck I didn't use a vacuum cleaner. "Bent" pin meaning its still there. As explained above, I was changing thermal paste. Nothing else. Use Msi afterburner to record temps 27-35C. Nothing indicates overheating.

"I ran a wire from the inside of the fan connector (on fan) into the space where the bent pin was". That statement suggests the pin is no longer there.

If the pin is still there, you can use a 5MM mechanical pencil to straighten it out. Remove lead from the pencil and slide the end over the pin. Work it straight. If a 5MM is too small then use a larger one.

You still haven't posted the EXACT error message you are seeing.

The pin is bent against the inside of the header, also that is the only error I get (90b). It is a black screen that says something along the lines of a system fan isnt working, contact hp support, system will shutdown in 15s, press enter to continue. Thats all of the error.
