Tech support for CPU problems
CPU model is a 5600H on a Lenovo IdeaPad gaming 15ACH-6. Over the last couple of months I've experienced random drops to 0.4 GHz, despite not overheating. Previously it would slow to 0.4 GHz at 80°C—the maximum temperature Lenovo set. At 60°C it would drop again, but after replacing it I thought that would resolve it; now it still drops unpredictably between 60-65°C. The GPU isn't overheating either, so the heat sink appears functional. Condition: Slowed | Condition: Working
Since the Christmas day 2021 laptop arrived, it often slows down to 400 MHz when overheating. Also, the original post didn’t mention that my machine stays around 45-48°C while idle—does that sound typical for a laptop? I understand it’s not ideal, but even without active use it can get warm.
Your laptop runs smoothly with a Core i7-10750H under normal conditions, but when battery is used, fans stop turning once it hits around 40°C. Even in silent mode, it stays cool at about 45°C. On low power, it drops to roughly 35°C while Spotify plays. Your current power plan might be set to a balanced or medium setting—consider switching to maximum performance for better efficiency.
I've got it set up with turbo disabled, though it's just building up altitude and giving a bit more frames per second. I keep my laptop connected since I don't need to move it much. Sometimes it keeps going over 65 without losing speed, which is puzzling.
I wouldn't configure the minimum processor state to 100%. I usually keep it at 0% since it lets the CPU sit idle, but your issue appears to be it staying stuck at idle speed. Could you download HWInfo and check the sensors section? There should be a part explaining what causes the CPU to throttle. This applies to both Intel and AMD processors—on your laptop it works, and on AMD systems it should too. You might also want to open BIOS and inspect power or thermal settings.
Attached photo shows the thermal throttle area. It’s unclear what details are useful here. I’ve used my BIOS several times and it’s now heavily restricted—I can’t adjust thermal or power settings. I understand this CPU has a 45W TDP, but I haven’t seen it exceed 20W during recordings since the problem began. Is that typical? Could Lenovo be limiting the TDP?
