I recently purchased a used Dell OptiPlex 3050 micro with an i5-7500T, 16GB RAM, and a 256GB SSD. Right away I realized the system wasn’t working well. It ran extremely slowly even for simple tasks like opening a new browser or adjusting settings. Task Manager showed the CPU stuck at 0.79 GHz. After checking online, I understood the problem: I performed a standard PC reset via recovery settings and applied all Windows Update patches. My power plan was set to balanced, and the processor was at full speed (100%). Both Intel Speedstep and TurboBoost were enabled in the BIOS. Despite these adjustments, the CPU remained stuck at 0.79 GHz and didn’t change with workload. I found ThrottleStop useful for similar cases, so I downloaded it. Since I’m not comfortable with advanced configurations, I tried disabling the Turbo option in ThrottleStop. That resolved the issue—processor speed rose to around 1.6 GHz with Firefox and light apps, then up to about 3 GHz under load. I’m considering leaving it like this, but I noticed ThrottleStop was recommended to fix this exact problem. If I need a solution without using the tool, I’d appreciate some guidance.

Explore the BIOS settings and take a look. This typically happens in Dells when the CPU multiplier is misconfigured. If you're not sure, simply reset it back to factory settings—it should resolve the issue according to my experience with Dells. Your previous owner likely tried adjusting it to run a non-K CPU, which isn't supported.

On my machine, you press F2 to enter the BIOS and F9 to restore defaults. If uncertain, consult your system manual on the Dells support site or search using the service tag.

Return to BIOS defaults. No overheating detected, so likely a software issue or faulty hardware. Verify all fans are connected properly, and consider reapplying thermal paste if needed.

I restored the BIOS configuration and received a curious notification during startup. I examined the power supply it uses—it's a third-party model. It delivers 65W, matching the specifications in the manual, yet I suspect it's not a Dell-branded adapter.

It seems you require the appropriate Dell adapter.

It seems the issue probably stems from restricting CPU power, which the previous owner may have silenced in the BIOS. Find a genuine OEM unit or consider returning it.

Several Dell laptops must operate at the lowest performance level when a Dell OEM power adapter isn't recognized. To avoid this issue, you'll need to keep using ThrottleStop for optimal results. Share screenshots from the ThrottleStop FIVR and TPL interfaces if you require assistance achieving peak performance on your T series CPU.

I acquired a Dell power adapter, the BIOS warning disappeared, and the throttling problem resolved.
