Laptop running slow on battery

My Laptop is acting weird now..

Whenever laptop is on Power supply plugged in, it runs normally, but whenever I disconnect the power supply or when there is sudden power cut, it becomes damn slow .

Please note that my laptop battery is 70% worn

Below is the screenshot of system spec along with the CPU and HDD temp. (screenshot taken after 10 minutes when the laptop was turned on)

Hello,

I prop my old Dell Latitude D820 up with a few comic backing boards to increase airflow underneath and she stays pretty cool. It will get warm (fan begins to run a lot) when I'm playing a flash game mostly, perhaps if I have many applications open, but for the most part not too much trouble As Brink said, try to get some airflow as keeping the vents plugged up won't allow for air transfer.

Also make sure you keep the keyboard and other components clean. Your fan can get clogged, but I use compressed air to give everything a good spray, but I do not take mine apart to get to the actual fan itself, as I haven't had many overheating problems (except in the summer then it's already blistering hot)

Hello Bindoksala,

Your temperatures are pretty high. I would recommend to increase air flow and blow out the dust to help cool the temps some.

If your laptop gets to hot, your CPU's and motherboard's performance could get idled down by your BIOS to help prevent a meltdown, or the laptop could even get powered off.

Since your laptop is only doing this while on battery, you might check your advanced power plan settings to see what you have set while "On battery", and adjust as needed. Specifically, check your "Processor power management" settings for this.

Power Plan Settings - Change

Hope this helps, :)

Hi Brink,

Below the laptop I have three cooling fan, yes I may need to blow the dust out.

My laptop behave this way when the power cord is plugged out, but when I again plugged in then also it is slow, then after some 5-10 it starts working nornmal.

For your information "Maximum processor state on battery is 80%"
