Performance drop 10 minutes after system start & CPU Clocks stuck low
Hello friends ,
I have a Lenovo Ideapad z510 laptop i5, 6Go Ram, Windows 7 Pro 64x about 5 years old.
Last week , i started having a problem with the battery, the laptop is plugged-in , it says charging but the battery percentage won't go up , stuck at 0%, i tried couple of things like disabling and uninstalling the ACPI Microsoft and the Microsoft adaptor and enabling them again, i tried discharging the pc , but that didn't fix the problem, i guess the battery just died , if you guys have a solution for that , i would appreciate it.
Now i only mentioned the battery problem to give as much informations to help you understand what is going on with my pc.
My major problem now is , that after coming out of sleep mode, the pc become slow and it's like the processor isn't performing as it used to be, for example , can't watch youtube/twitch in 1080p or higher, it doesn't buffer but it lags (stutter) . It only get fixed if i restart the pc. But now the problem is even worse, if i start the pc it works perfectly fine , but after like 10 minutes the lags and stutters beggins, i didn't put it to sleep mode, it just starts becoming slow and when i want to watch high quality videos online,it stutters. I was playing a video game and was having like 130 fps which is normal to me, but then all of sudden it became 20 fps .
After booting ,the computer works perfectly fine, i can watch high quality with no problems , the processor seems to be working fine, i can hear the fan blowing fast because it's hight quailty stream, but when it starts stuttering and the pc in gerneral become slower, the fan speed is so much lower , like the processor is not making an effort .
It's not an over heating problem, because when it works fine, the temperature is around 70Celsius/158Fahrenheit which is how it noramly is when i didn't have problems, but when the problem accure the temperature drops to 53C/127F .
Using HWmonitor, the cpu clocks is at 2996 MHz when everything is fine but when it starts stuttering the cpu clocks drops to 799 MHz.
As i said ,it feels like the processor isn't running at full capacity .
I tried restarting the pc over and over, i run cmd , sfc /scannow and no errors were found, i ran chkdsk commands but the problem wasn't fixed , i reseted the bios to default settings , but still nothing, i updated video drivers , still nothing.
I hope i explained it well enough, sorry if it's not so clear, please feel free to ask me any questions you have.
