Why is my CPU stuck at 0.2 GHz clock speed on Acer Aspire A514-54G?

sandzzzzz

I have an acer aspire 5 i7 11th gen, 20gb laptop. It's brand new and the laptop is lagging too much as it is stuck at 0.2 GHz even without any task. Takes a whole bunch of time while booting up and everything is very slow. I surfed through the internet and found that bd prochot feature is limiting the performance even without any heating issues. So, I installed Throttlestop software and uncheck the bd prochot box. It completely solves the issue but is temporary as I have to manually start the app to unfreeze the clockspeed. I even tried to launch throttlestop at startup but the booting time is huge. I also tried to change the settings in the UEFI settings but I couldnot find any options related to this. Can anyone please suggest me the permanent way to fix this issue?

Welcome @sandzzzzz,

Please tell us the model (full name) of your Aspire laptop.

The BD PROCHOT signal can be triggered for a number of reasons:

• Faulty battery;
• Charger circuit;
• EC controller;
• Faulty DC-in Jack and/or Charger source;
• USB / USB-C PD ports with excessive power consumption;
• GPU and/or VRAM chips overheating;
• Voltage regulator circuit (VRM) overheating;
• RAM modules overheating;
• PCH overheating;
• Overclock (firmware UEFI or VBIOS mod)
• Faulty read sensor(s) (e.g. temperature control, FAN rotation, lid opening and closing, G-SENSE).

According to the creator of the ThrottleStop tool, this last item is one of the most difficult to diagnose! You'll need a schematic of the motherboard to identify and locate the exact location of these sensors.

If your laptop is new and still under warranty, please contact Technical Support / Authorized Reseller to request a replacement / repair (RMA).
