Lenovo Desktop: Why is my CPU fan, fast and furious mode?

Mon, 06 Apr 2026 15:57:15 -0700

After doing the usual maintenance routine, brush, and pressure aired the whole thing. Connected it and the cpu fan turns on max speed. I get an image, but when almost done booting up, it freezes. I checked it and found the THER_HD cable had come off where it connects to a transistor 2N3804924. I soldered it back. Cleaned and oiled cpu fan. Took out Ram and cleaned it as well. Plugged it back in. And still doing the same thing. Im all out of ideas.

Lenovo ThinkCentre: Post beep code is 3 long, 1 short, no solutions found.

Mon, 02 Mar 2026 04:19:10 -0700

I got a Lenovo ThinkCentre m920q at a Goodwill for $4. After getting a power adapter for it, and disassembling it for curiousity, the power button light and the red thinkcentre light glowed and fan spun. It then beeps 3 times long, then 1 time short. Thinking the problem may be ram, went to microcenter and got a new sodimm ddr4 8gb. Produces same result. The video is with the new stick of ram. Typing anything on a keyboard when it’s on (f1, f2, delete, enter, etc.) does nothing. Any thoughts?

Lenovo Legion Desktop: Pc not booting up normally

Thu, 29 Jan 2026 08:27:56 -0700

One night i went to sleep and than when i woke up my pc wouldn’t turn on normally. The fan rgb lights would turn on and fans including gpu fans would spin but that’s it. My mouse lights or keyboard lights wouldn’t turn on and my monitor would detect something which it says “No Singal” everytime i turn it on and than just automatically turns back off. Recent thing that happened is when i disconnect my gpu my mouse lights would turn on but not my keyboard lights, and every time i put it back it would just not work at all.

lenovo C560: Why doesn't my LG 🛜 headset work n my brand new Lenovo idea center PC

Wed, 28 Jan 2026 03:38:26 -0700

I work from home doing inbound and outbound sales. I can hear and talk to my supervisor and other reps. But when I get a call I can't hear the customer. I can hear the tone when the call connects. The system shows that my microphone is working just fine. It's only when a call connects that my audio isn't working right and I can't hear the customer. when the call is over my supervisor gets connected to me on zoom and I can hear her. One day worked perfectly fine. And the next day this happens.
