lenovo idea pad z410 keeps throttling

My laptop was working fine while i was playing (league of legends to be exact) when suddenly my fps went down greatly then i found out the problem was my laptop was running on 800MHz (using realtemp) and won't go up. I could not find the problem much less the solution. When i couldn't find anything i tried the one key recovery to revert to factory settings, but still the problem persisted. I found on the net that most people with this problem used throttle stop so i did too. It was working fine but then my charger broke (my battery is dead too, broke around a week or two before my charger). I thought that my charger was causing the throttling because my laptop worked great again after buying a new charger. But that lasted only for a day. It is now throttling again at 800MHz. I am afraid that something will break again but i can't seem to find the problem. temperature is consistently around 40-60 degrees C. I hope someone knows or previously had this problem that found a solution. or at least knows exactly what the problem is. Thanks in advance

Re: lenovo idea pad z410 keeps throttling

Addition to Krakken, Your CPU / GPU might be overheating and it's throttling down - this would cause your CPU / GPU to operate in a low frequency, thus giving you low FPS. Try to monitor your CPU by using CoreTemp and your GPU by using GPU Shark or Afterburner.

 

If you get high temperatures, you can try to decrease the heat by:

 

  1. Using a good quality cooling pad that runs on high RPM or a better cooling in your room.
  2. Replacing the stock Thermal Interface Material with a good quality TIM like Noctua NT-H1Tuniq TX-4, or Artic Silver 5.

Update us how it goes.

Re: lenovo idea pad z410 keeps throttling

What charger were you using? You say you bought one. (not under warranty for it??)

 

The charge need to be the high powered model. 6-7 amp rating I am not sure if its 135 watt or how its rated. A smaller one will not provide enough power to run in Performance mode plugged in an may not even charge the battery.

T520 Model 4239 Intel(R) Core(TM) i7-2860QMbr>; Nvidia NVS 4200M Win 10 64bit
Z70-80 I7 - 5500U 16GB GB - 1TB HD Win 10 64bit FHD 17.3", G840 w/2GB
