Laptop System Fan Failure

I had a HP laptop that was giving a system fan failure message on boot. The service code from HP was 90B, but related codes on HP’s website show it might also be a 900, 909, 90A, and 90F code. The CPU fan would spin up and down constantly and the CPU speed was capped at a very low speed. This made the laptop very slow.

I fixed this by disconnecting the fan and hard drive, turning on the notebook computer, then turning it off, and re-connecting the fan and hard drive. After doing that, everything worked just fine. This simple fix might work for other laptop computers.

There are some others things I recommend doing while you are doing all this.

Windows 11

I have just bought a new laptop just so I can experiment with Windows 11. I eventually settled on the Lenovo Legion 5 Pro Generation 6. I chose this one only because of the screen. It has a 16″ screen (instead of the standard 15.6″ screen on laptops) that is Dolby Vision certified. I thought about some with an OLED screen, but you have to be careful with image burn-in for those screens. This laptop was on sale and I had a coupon. With tax, I paid $256 less than the MSRP (which doesn’t include tax). And even better, it shipped from Durham so I got it the next day! (I always thought it was funny that Lenovo, a Chinese company, still builds computers in North Carolina but HP and Dell, American companies, build most of their computers in China.)

These are my experiences with Windows 11. I am going to save you some time and sum up my experiences so far with this statement: overall, Windows 11 is even worse than Windows 10.
