Is it Okay to use laptop while charging? Does it have any bad effect on battery or laptop?
答案1
As long as the power supply can provide enough power for simultaneous normal operation and charging, there should be no issues.
答案2
Well usually it is suggested to keep the power of laptop unplugged when using battery, otherwise it affects the life of the battery. Direct power AC should only be provided to the laptop when the battery charge is approx 25-35% that is recommended. I've also seen people take out their batteries and use their laptops directly with AC power if there is no portability or power problems.
So it is not advised to keep the power plugged in all times, it destroys the battery and lifespan is affected inshort!

Keeping a battery in all times smooths the power delivered to the computer, this can have a positive effect on the internal components.
Over the life of a laptop, you are likely to run in to other major faults before the battery gives up.
