Question

Laptop Slows Down While Charging, Please Help

Jan 27, 2015 4:40AM PST

Hello everyone,
Recently I have found out an issue with my Dell laptop, been going on and on trying to find out what is going on and I only found the thing that causes the problem but I cannot fix it on my own. I have an i7 Intel processor 1.80 GHz, with turbo boost. The thing is when I have my laptop plugged in, the CPU seems to be not functioning the way it is supposed to. For example, I downloaded the Intel Turbo Boost Monitor and when my laptop is unplugged and only works with its own battery life, the meter shows up to 3.0 GHz, and immediately when I plug it in it drops in 1.80 GHz. This affects the performance of my laptop on everything I do, from opening a browser to playing a game. Here is a list of the things I have tried to far:

- Updating my graphics card
- Updating BIOS
- Using a laptop cooler
- Change my battery power settings to high performance

None of the above managed to assist me with my issue. If you have any thoughts on how to fix this, how to let my CPU work on its full potential even when my laptop is plugged it would be much appreciated.

Many thanks
