Laptop lagging when plugged in.

[Bashar_Ahmaro]

I have a Dell inspiron 5558 i5-4210U it lags while playing games (i.e BF4) when it's plugged in but runs smoothly when on battery.. Can anyone help me please, I tried changing the advanced power settings and updated the BIOS but nothing happened... Thank you.

Hi,

Please do try these troubleshooting steps that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If the same problem will persist, do a clean install of the graphics card driver.
- Go to Device Manager and uninstall the Nvidia graphics driver.
- Next is to open Programs and Features then uninstall anything related to Nvidia.
- Once completely uninstalled, download and install the latest driver.
- Here's the link: nvidia.com/Download/index.aspx
- Reboot the laptop once the latest driver has been installed.
- After the reboot, do test it again and see if the same problem will persist or not.
- Do also change the power management settings in Nvidia.
