s510p ideapad bios problem

so when plugged into the adapter, my computer runs slow/lags,but on battery power, it runs much better.

 cpu i7 4500u 1.8mhz  up to 3.0 mhz when plugged in cpu = 0.7 mhz  but on battery cpu = from 1.8 to 2.9 mhz 

I've tried many things, and have read many other forums. I just want to find an actual solution. I've done many of the obvious "fixes," such as updated drivers, modifying power plan, and viewing task manager.

Re: s510p ideapad bios problem

Hi there, Benzita         -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

There could be background takes running, such as HDD indexing that don't run when the machine is on battery power. These background tasks could cause the computer to slow down when plugged in.

 

The system is designed to be run with the battery inserted. Removing the batter when on AC power can lead to slowdowns and system instability.

 

Update us how it goes.

Re: s510p ideapad bios problem

In the Windows Power settings, there should be a link that says "Advanced Power Settings." Make sure that everything in here looks as it should. In here you can change settings for processing power for the system when it is plugged and in when it is running on battery. The settings somehow could have changed so that the processor power slows down when it is plugged in. I know you've changed the power plan, but make sure you verify these settings as well.

 

Update us how it goes.

Re: s510p ideapad bios problem

Have you looked at your component temps, charging generates a lot of heat, it would be its overheating and slowing down to protect itself when charging. Get a system monitor program that monitors CPU temperatures.

 

Update us how it goes.

Re: s510p ideapad bios problem

Are you using the original charger? Does it slow down immediately when plugging in the charger, or after a few minutes?

 

Update us how it goes.

Re: s510p ideapad bios problem

It could be a faulty charging cable, or a faulty battery. If your charger is low output or worn out, it could mess with some graphics drivers and slow down your pc. If it is under warranty I would recommend contacting Lenovo service centres and applying the normal phone techniques to get it replaced promptly.
