Windows 7 64 - bit system, connect the power supply when it opens at right click menu on the desktop, fast, but pulled out after the power on your desktop click to open the menu in the process of a busy cursor will have a long time, about a second or so, doubt is the set of power options, but I don't know why are set to high performance,

If does not affect the use, the difference of 1, 2 seconds has nothing to do,
To find out the problem, just have a look at each set power options, such as the processor frequency, etc

CodePudding user response:

Some laptops have a dedicated power supply driver, suggest to check the power supply driving module is not installed or update the driver,

CodePudding user response:

You are feeling much brighter screen, the power is connected have similarities, isn't it?

CodePudding user response:

Laptop plug and plug performance must be distinct. In order to ensure the laptop battery life, so will reduce the performance, reduce power consumption, at the same time, the screen will darken. Set the best performance can reduce the gap, look at the options at the same time can click on the following power supply more. Set to higher performance

You said these I know, no connect power in power options all the options (brightness, CPU performance, etc.) set all became the highest performance, pull the screen dimmed

Reinstall the power driver?

Practice, I also found some laptop even when the battery is set to "high performance", in the circumstance that does not meet the utility still feeling you have difference and the utility, suggest the landlord to do a test, there used to be a statement, but not confirmed that is even set into the use of high-performance batteries, CPU and graphics will be forced frequency reduction, the original poster to verify that the CPU can be used to Z tools such as real-time test isn't that true, looking forward to your feedback,
